If your TV isn’t working properly, there are still a few things to consider before you give up on it. Generally, you’ll have a few warning signs that things are not exactly right.

Of course, sometimes, the TV is beyond repair and you should replace it instead. If the screen is broken or the TV doesn’t turn on no matter what you do (or if the sound stopped working completely), it’s time to check out a new set.

The difference is that stuck pixels usually happen because of a problem with a transistor; they often have different colours and are usually just simply out of place. If it is a dead pixel, then the TV should be sent for repairs, as, unfortunately, the issue is a difficult one to fix.

If the colours on your screen appear distorted, then your TV might be malfunctioning. Traditionally, this issue tends to occur gradually, meaning that you might not notice any difference at first. This is due to the common factor that one colour tends to weaken at a time; therefore, no obvious changes happen overnight.

If your screen starts to display bars and lines, this tends to indicate that there is an issue with a connector. This can occur when something magnetic has been placed near the TV and, in turn could mess with the picture quite considerably, even potentially de-magnetising the screen.

The issue can be due to cables that have become loose inside the screen as well, which is an easy fix, although it may require a professional because the TV may have to be opened.

You may be able to do something about this by adjusting the levels of brightness and contrast on your TV and playing different types of content to see if the problem goes away. You can also enable your TV’s Pixel Shift feature; when this feature is turned on, images on the screen move a bit to vary the pixels used. Pixel Shift is often included in modern sets and might clean out the phantom image.

This issue could occur if the signal received is a digitised standard (480p), as there’s a discrepancy between the resolution and the display. It’s also worth noting that the digital signal your TV receives can be affected by weather conditions as well, so the image can appear fuzzy and glitchy.

However, the good news is that, when this happens to modern televisions, there is a high chance of it being fixed, so you can still enjoy your TV for a long time.

If the TV is on but the picture is faded on some areas of the screen, it’ll be difficult for you to actually enjoy the content. You may try to ignore the stain-like mark but there is no denying that this will impact your experience. Faded spots are not that rare and can be accompanied by other serious issues, like your image fading to black after you’ve turned the TV on.

Since TV is used practically everyday for hours at a stretch, it is bound to have some issues over time. Some of these issues can be taken care of at home, while some serious issues may need help from a professional.

If you notice vertical lines on your TV screen, this is a serious issue and should not be neglected. This problem usually occurs if there’s a loose cable wiring, loose or faulty board or a damaged screen.

This is a common problem in TVs and is a sign that your TV panel is failing. But before you call an expert to check the TV, you could try following these steps and check if they work:

Turn off the TV and unplug the AC power cord (main lead). Keep it unplugged for 15 minutes and then switch on the TV to check if the issue has been resolved.

If it continues to show lines, you may mostly have to get the panel replaced and replacing the panel can be a costly affair, depending on the TV and its model. LED panels range anywhere between Rs 8,000 to Rs 85,000, while LCD panels range between Rs 6,000 to Rs 25,000.

Try increasing the volume to the fullest on your remote to check the sound. Ensure the TV input is correct, the TV is not on mute mode or no headphones are connected to the TV audio out jack on the side or front of your TV.

Also, check if all the cables connected into the back of your TV are proper and not loose. If there is still no sound, you will need to call a professional to open the TV and check the circuit board.

When the TV has speakers that work perfectly fine but it has no picture, there is mostly an issue with the back-lighting system or the power supply board, which will need to be replaced. In the case of an LCD TV, it works with the help of a backlight that is used to illuminate the picture on the screen. When the backlight begins to have problems, the screen turns blank.

To fix this issue, the backlight will have to be replaced by a TV expert. Another possible reason is that the backlight on the LCD TV which has a power inverter has failed. When this happens, you may need to replace the inverter or the capacitor.

This is again a common issue that most people complain about. While switching on the TV using the remote, if you notice that the light blinks but the screen is blank, this is an electric connection-related issue.

You could try disconnecting the power cord from the unit and wait for 10-15 minutes before you plug it back in. If this is just a simple electric connection problem, this should fix the issue. If the screen still doesn’t turn on, you will need to call a TV expert to resolve the problem.

There could be several reasons for a flickering TV screen, which is mostly a common issue with LED TVs.One of the major reasons for this is loose or defective cables that result in screen flicker.

Be it a panel issue or a major technical issue with the TV, resolving these problems is a costly affair. It’s best not to ignore any of these signs and call an authorized TV expert before the problem worsens.

Buying a television is a long-term investment, so do not compromise. Buy one with a minimum of 4K resolution because new technology like OLED and HDR is pretty much only on 4K TVs.

Choosing a TV size plays an important role. If the screen size is too big for your room, you may notice the loss of clarity. To measure the distance between the sofa and the TV. If the viewing distance between the sofa and your TV is between 5 – 10 feet, a 40 – 42 inch TV should be perfect for your room. If the distance is less than 5 feet, a 32 inch should work best.

Don’t just ask for a smart TV. Most TVs available today are smart TVs with easy access to Netflix and other online apps. So do not be tricked into buying one just because its a smart TV.

The difference between a LED TV and a LCD TV is that they are both LCD TV’s except one has LED stripes and the other has CCFL Backlights- (Florescent Tubes). I used a Philips Magnavox Emerson LG TV when testing these repaird, but they should work on other TV brands that are similar. Before you do any Repair, check to see if you are still under warranty, or are covered by a recall of your TV!!

If your Plasma or LCD/LED or CCFL/LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it *may* need some new capacitors in the power supply board or a replacement board

-Upon three unsuccessful start up attempts the TV locks itself in protection mode and needs to be disconnected from AC for 30-40 seconds before power attempts can be restore-Display Locks after 10 minutes–

1) the front green LED of your TV comes and stays on for 20-30 seconds, then turns off for 1-2 seconds and then keeps cycling like that, but the display never comes;

2) the display comes on for a brief few seconds, then the TV shuts off; in some models the display may not even come on, but still the relay clicking on and off and the green power LED activation and shutdown can be easily observed.

A model number is needed to determine the unlock procedure, but most likely you will need a remote to unlock most TV’s. Below is a common lock procedure.

Choose On to disable all the buttons on the front of the TV. FPA Lock On will appear on the TV screen each time you press buttons on the front of the TV. You can still operate the TV with the remote control. You can still use the POWER button on the front of the TV, but only to turn off the TV (not on). Set FPA Lock to Off to cancel this feature so you can use the buttons on the front of the TV again.

3. Press and hold each of the remaining buttons on the TV, one at a time, for about five seconds, and then release. DO NOT use the buttons on the remote control - only use the buttons on the TV itself.

6. The TV should start automatically scanning for active channels from your input signal source. Make sure you have a good signal (antenna or cable or satellite).

If the TV still does not display anything, try the menu button on the TV and see if you can access the menu. If not, try using the remote control’s menu button.

If the TV is still locked and will not respond to any commands from the front panel control buttons or the remote control unit, it is apparently locked in a failure or diagnostic mode, and would probably have to be diagnosed and repaired by a reputable TV repair facility. Good luck.

If it is a thin vertical line that appears on certain video resolution/image then it is normal and is indicated in the users manual under troubleshooting. If the line is almost half the screen, it could be a problem with the cable connection between the LCD panel and logic board, or the LCD panel itself. Try reseating the cable first if it’ll solve the problem. I’ve done similar issue in the past. Reseating the cable worked for a couple of months till eventually the LCD panel is the problem. Replacing the LCD panel is quite costly and impractical.

If the lines are there all the time or intermittent but in the same location it is an indication of a bad panel. The panel driver can also be the cause of this symptom.

If the lines/bars are across the OSD Menu, and all the video signal inputs also same result, that means the TV LCD Panel is defective Most of the time this symptom is caused by a bad LCD Panel 95%. You can try refitting LVDS Cable or replacing Main Board capacitors or replacing Main Board—5%

Bad news unfortunately, their are two possible causes for what you have described, one would be a fault with the picture drive pcb ( Power Control Board ), and the other is physical damage to the LCD cell matrix, (screen).

There’s videos on how to fix this. It has to do with putting foam, in between panel frame and screen, which applies pressure to solder joints, which then completes the circuit- Contact my10cents, for better explanation.

Big Black Bar on bottom of TV Screen– If the bar that appears in the bottom is showing the energy saving logo, HDMI, Dolby surround and pc mode capabilities look into your remote.

Is the OSD menu affected as well? If yes then possibility could be the LCD Panel or the t-con board. Since you have replaced the t-con board then possibility is the LCD panel. There could be also a possibility of mainboard where upgrading the firmware could restore the picture. If the OSD menu is not affected then the LCD panel is good.

If the lines are across the OSD menu then chances is very high the LCD panel is the cause of the problem otherwise it can be due to bad T-con board or even Mainboard. Have you tested on the OSD menu to see if the lines are really across the menu?

White Lines– There are several possibilities that can cause white lines on an lcd screen. One would be high temperature on the logic board. Logic board drives the LCD panel and when it overheats can cause this display problem. One solution would be to clean the vent holes around the TV. One possibility that I have experienced myself servicing is a bloated capacitor on the power supply board. The worst possibility is a defective LCD panel, which is costly to repair, and sometime more practical to buy a new TV set.

Do you get blue screen when using x-box or DVD, VCR? Have you tried to reset cable box if you have one? Reset TV. Check all cable connections? Try these first.

Do you use the Set top box for cable channels? If yes then try connecting through HDMI and see if you can see the TV. Also do you get blue screen when using x-box or DVD, VCR?

What made you decide to change the mainboard? I ask because if the MENU does not appear, then this indicates a problem elsewhere within the TV. Also, did you check for any swollen, or bulged capacitors on the power supply board?

There are several problems that could cause this problem. It could be the connection from the T-Con board to the panel, try wiggling these cables around and see if the picture comes up even for a second. The Mainboard or it’s cables are not the issue in my opinion. The isdsue is either going to be a bad capacitor, faulty output from the power supply to the T-Con board, a bad connection from T-Con to panel, or the T Con or the panel itself are faulty.

Basic things you can do is to check the connections. If you have a cable box, check the video connections. And while doing that, unplug the TV and the cable box from the AC outlet for it to reset. These are the most likely cause of a blue screen

Most of the new TVs display a blue screen when theres no signal for it to lock on. Try unplugging it for about 5-10 minutes and see if that clears up the problem. Why? Because they have microprocessors in em (computer chips) and just as like with any other operating system, they can hang up or crash. This isnt an uncommon problem with todays TV sets. Unplugging it for awhile resets the microprocessor (in other words, it causes it to re-boot when you plug it in again).-

It could be the connection from the T-Con board to the panel, try wiggling these cables around and see if the picture comes up even for a second. The Mainboard or it’s cables are not the issue in my opinion. This is due to either a bad capacitor, faulty output from the power supply to the T-Con board, a bad connection from T-Con to panel, or the T Con or the panel itself are fault. Also, it’s possible the A/V receiver’s Video On feature was turned off by an electrical surge or something else.Turn the Video feature back to On and suddenly that bad blue screen was gone.

Repair/Solution: Change the cable box to a fixed resolution. OR have the customer install the latest TV firmware which can be located at your TV Brand Customer Support

Your power board needs serious help–If you want to repair you have to replace Switching Mosfets, disc capacitors and of course the main fuse, Rectifier Diodes and most of the time the transformer–Costly–Easier to replace Power Board–There is a chance the strike come through the cable line, so it’s possible the Main Board needs repair–That’s a small chance though, but I thought I’d let you know–Replacing power board should repair your TV. During a lightning storm, electrical power surges is induced to the transmission line eventually end to our household appliances. Our TV sets, computers are the most susceptible. For the TV set, the basic cure is to leave the TV unplug from the AC outlet for it to discharge and reset

5. wait another 30 seconds and some type of picture should appear—If that does not work–Unplug TV for 10 minutes and then hold power button on TV for 60 seconds–Plug in and turn on.

Unplug TV– On TV, hold the power button down while pushing and holding each button for a few seconds. After going through all buttons, (on TV) then plug TV back in and it should power up–

When the TV, has no Picture or Sound. Led turns from red to (Blue or Green). It means the Main Board has sent out the start up signal to the PSU (Power Supply) Board.

Now we need to know if PSU Board has all the correct output voltages. This means checking the secondary side output voltages of Power Board. Probable causes are the Power Supply, the T-Con board, Main Board or the LCD panel itself has failed.

No Picture/Sound The person who looked at my TV, stated that the high voltage power supply needs to be replaced. He explained that I have a low voltage supply which is why the power button is lit once pressed, and a high voltage supply which needs to be replaced.

You will have to go into the TV and check for capacitors or burn marks or cracked solder around the pins–Main board could be IC’s, or regulators–Panel–Disconnect panel and see if your TV stay’s on—

The flashing green light indicates a fault on the power board inside your TV. This will be due to a faulty component like a capacitor or voltage regulator. Faulty electrolytic capacitors on the power board are the most common cause of this problem. These capacitors will often leak and stop working as the TV set gets older,but could also be caused by the Main Board or the inverter board. (LCD TV ONLY) So we will have to take a look inside and maybe do some circuit testing and a visual of your boards-

In a dark room take a flashlight and at an angle shine it on the screen and see if you can see any movement. If you can see movement or see your menu then its backlight failure. If totally black screen with sound then its T-Con board. So if you see movement on a led screen, then it’s your LEDs inside the panel. If on a LCD TV you see movement and lamps are not turning on, replace inverter. If with a LCD TV your lamps turn on, with no picture replace T-Con Board.

Plasma is the most durable in terms of panel failure. LED/LCD is terrible for panel failure. (But every model gets bad apples. Samsung LED/LCD panels die frequently. LG panels are a lot more reliable.) Overall I’d say plasma is more reliable, and even if it fails, in most cases plasma is repairable, LED/LCD is expensive to repair and often difficult to troubleshoot.

A blurry image on a high-definition LCD TV is typically the result of a mismatch between the TVs resolution capabilities and the resolution of the signal that is coming from connected devices, such as a DVD player or satellite TV receiver. Typically, blurry pictures result when a peripheral device connects to the TV through non HD cables and jacks.

First, I would like to mention that both an LED TV and a LCD TV are actually LCD TVs except that first one has LED stripes and the latter one has CCFL Backlights- (Florescent Tubes).

This Blog is just Symptoms and Repair of different Models in Alphabetical order. These are real case history Symptoms and Repairs. For more information about different symptoms, sound, picture display, etc. and general repair tips, please visit my other blogs.

329 Cases, for Dynex, Emerson, Funia, Hisense, Hitachi, 1 ILO, Insignia, JVC, LG, Magnavox, Panasonic, Philips, Polaroid, RCA, Sansui, 1 Scepter, Samsung, Sanyo, Sharp, Sony, 1 Supersonic, Sylvania, TCL, Toshiba, 1 Trutech, 2 Viewsonic, 2 Viore, Vizio, Westinghouse, TV’s

Symptom-The red “power” indicator turns on normally but when I try to switch the TV on I hear a click, the red power indicator turns blue as usual but the screen remains dark and no sound

Repair–Stuck “Tact Switch” on TV volume down– You can either press volume down switch 20 times with TV off–(Oxidization), or replace Button Key Board or if you can, disconnect Button Key Board from Main Board–

Repair- Suspect a stuck VOLUME down(-) button. A normal button will give you that tactile feel, compare it with the other buttons. If it feels similar to the other buttons then it could be the switch behind that button. The switch used in most front panel buttons are called ‘tact’ switch, obviously named because of that tactile feedback

Symptom-The TV would fire up with a request to Auto Scan Channels. If I selected this it would perform a scan and revert to the same screen. I could not get remote controller to work reliably, nor keypad functions on the set to function properly. Repair-unplugged the control button / control pad keypad from the main control board. TV works with remote

This means that the Audio Processing Circuit on the Mainboard of your TV has failed. The mainboard is the board that houses all of the Audio Video jacks on the back of the TV and is accessible/replaceable by removing the of the set. You would need to replace this board to fix the problem, and it is a fairly common failure in this TV.

Repair–Suspect T-Con Board–Sometimes, just resitting, unplugging and re-plugging the flexible ribbon wire from the T-Con board to the LCD panel, will fix it-If not replace T-Con Board-

Symptom-I turn on my LC320EMX 32 tv. and the screen with “digital television” on it appears, but then it shuts off after 3 seconds and goes directly to standby mode

The 10 flash error code is because the power is disrupted do to a short to ground in one of the LEDs. I was able to get the TV to work by soldering a jumper wire across the burned out LED, but I believe the increased wattage on the rest of the LEDs causes them to burn out prematurely.

Symptom- My Hisense TV will not turn on. Model number LTDN42v68us. When it turns on the red light is on indicating it is off. When I try to turn on it flashes between the blue light and the red light 3-4 times. Then stays blue. Blue will not go away. If I hit power button again it stays blue.

Repair–I used the buttons on the side of the TV rather than on the remote. Volume - and Menu whilst switching on at the wall, then power on and release all 3 buttons. Took about 20 seconds and then back to normal. You may have to do this more than once–

Unplug TV for 10 seconds at least. Then, press and hold down the “MENU and VOLUME DOWN (-)” buttons, at the same time for about 10 seconds. Then after 10 seconds of holding the 2 buttons down, continue to hold the 2 buttons and press and let go of the power button. In other words after 10 seconds of holding down the volume down (-) and menu buttons, add the third button (power) and immediately let go of all 3 buttons, at the same time–

Repair–Replaced T-Con Board–No change. Found shorted VA1-(Variable Resistor) Since it is on the Control Board, which is Micro Soldered to the Panel and cannot be replaced, it`s considered as panel failure-

Repair–The internal LED’s have burned out, causing the entire led strips not to operate. Either the led strips would have to be replaced if available or the bad LED’s would have to be bypassed.

Activate the TV’s menu — let’s see if that flickers too. We want to see if the menu flickers, because it might be only the TV’s picture that flickers. If the menu flickers, then we know we’re dealing with the panel or the TCON. If only the picture flickers and the menu is steady, then we know we’re dealing with the Main board.

Sony LCD TVHas dim picture–1 of the CCFL(cold cathode fluorescent lamp/light) could have burnt or the circuit(inverter) that powers it might have failed. A technician will usually swap the connectors between the suspected dead lamp with the other good ones. The backlight consist of more than 2 CCFLs. When swapped and the dark area is at the same location then you have a bad lamp, otherwise suspect the inverter.

The most common reason is that your TV is on the wrong input. You can typically change the input by pushing a button on your TV remote labelled “input”, “source”, or “TV/Video.” Keep pushing the button to cycle through the inputs until you have your picture back.

There’s nothing more annoying than when you see someone’s mouth moving, but what you are hearing is not in sync. You see someone’s mouth say “hello,” but then you hear “hello” after the mouth stops moving. It’s like watching a foreign film with a voice-over. You will want to go into the audio settings of your TV or cable box and adjust the “audio delay.” This should get you back in sync.

If you’re hearing an echo, you probably have a separate sound system, like a soundbar or surround sound system and you have the volume playing both through your external sound system AND your TV speakers. If you have a separate sound system, you DO NOT want to also have sound playing through your TV speakers, as it will always result in an echo, plus you paid for that separate sound system because it sounds so much better than your TV speakers. You will want to disable, mute, or turn the volume all the way down for your TV speakers and only use your external sound system. This should eliminate the echo.

If your TV picture is breaking up, cutting in and out, or pixelating (looks like everything is a bunch of squares), then you probably are experiencing a weak signal. Check all of the connections from the wall to your cable box and from the cable box to your TV to ensure that all connections are tight. If you’re still experiencing issues, you’ll need to contact your cable or satellite provider.

If your screen has lines, bring up the TV menu. If the lines run through the menu, or if the screen is cracked, your panel needs to be replaced. This is not a cost effective repair. If you have an extended warranty and there are lines in the panel, the warranty company will likely replace your TV. If the screen is physically cracked, this would not be covered by a warranty and you will unfortunately need to replace your television.

After a long, hard day, you finally sit down to catch up on your favorite show. But when you hit the power button on your remote control, your TV screen stays black! You try pressing the remote’s power button again and again from every angle, but still, your TV has no picture. If this sounds familiar, you’ve likely fallen victim to one or more TV screen issues.

What causes a TV screen to go black? Software issues, loose connections, or backlight problems are usually behind black TV screens. Learn about each of these causes and get tips for troubleshooting them so you can get back to relaxing with your favorite TV shows, movies, and video games.

If your TV screen is black and there’s no sound, you’ll want to check for an LED light or a small indicator light that tells you the TV has power. If there is no power to the TV while it is plugged in, there may be an issue with the outlet or fuse box in your home. However, if the TV is on but the screen is black, the problem could lie with your TV’s software.

Unplug the TV from the wall, and, if possible, remove the power cord from the back of the TV to perform a soft reset. Wait 30 seconds, and plug the TV back into a working outlet to test it again. If you’re still having screen issues, you might want to bring in an expert — they’ll know how to fix your TV’s black screen.

If your TV screen goes black but the sound still works, the first thing to check is the input source to ensure it is turned on and operating correctly. This includes external devices like cable boxes, video game consoles, laptops, and streaming devices. Once you’re sure the input source is working properly and you have the right input settings, check the cable connections. In many instances where the TV screen is black but the audio works, poor cable connections could be the issue.

Whether you’re working with an HDMI cable, RCA (usually yellow, white, and red cables) set up, or another type of connection, you need to ensure the cables are seated properly and firmly into their connection ports. With a good connection, the cable shouldn’t feel loose or easily disconnect when pulled on or moved around. If all your cables have a snug fit but the problem persists, try connecting the device to another TV. If your TV screen is still blacked out, you may need new cables.

Some TV displays, such as LCD screens, use a backlight to illuminate the picture. If the backlight burns out or stops working, it will result in a blank TV screen.

To check your TV’s backlight, make sure your TV is on. Then, turn off the lights in the room and shine a flashlight on the screen. If you can see a picture with the flashlight, then your TV’s backlight is likely burnt out.

While you might be eager to learn how to fix a black-screen TV, a broken backlight does not come with an easy solution. The backlight will need to be replaced, and it’s best to get help from a professional with this task.

Did your electricity bill jump from one month to the next? Or has it been slowly creeping up? Check with your utility provider and confirm that they haven’t raised their prices. Otherwise, an old TV or other major appliance could be to blame.

Here’s how to test out the theory if you suspect the TV is racking up your energy usage. Unplug the TV for a few weeks this month and watch how it impacts next month’s bill. Use your other electronics, like your sound system or computer, as usual to avoid influencing the result! This method can be used to test out the electricity cost of almost any appliance in your home.

Do you find yourself relying on your laptop for streaming? Does your current screen make your new game console’s graphics look like a bundle of pixels? If so, you’re missing out on the wonders of HD smart TVs!

Smart TVs are WiFi-enabled, allowing you to stream your favorite content without needing a laptop. HD and UHD smart TVs allow you to watch that content in vivid, lifelike resolution!

If your current TV screen isn’t letting you enjoy your entertainment options to their full potential, it’s a good time for a change. After all, what’s the point in paying for HD channels and top-of-the-line gaming systems if you can’t take advantage of them?

Does your favorite soap opera look more like your teenager’s tie-dyed leggings? If there are red, blue, or greenish stripes interrupting your viewing experience, there’s probably something wrong with your TV’s hardware.

Lines across a TV screen are usually to blame on loose or frayed cables within the screen, which is why knocking the side or back of the TV can be a temporary fix. (You’re knocking the cables back into place.)

Repairing this problem leaves you with two potentially expensive options: a) calling a professional repair person, or b) ordering the parts and opening the TV panel at the risk of damaging it permanently and voiding the warranty.

The TV is on, but the picture doesn’t look right. One side of the screen is faded. You try to look past the blemish and focus on the movie in front of you, but it only takes a few minutes for you to identify the real villain in this story: the faded quarter of your TV screen!

Sadly, faded spots on TV screens are not uncommon. What’s more, they may be accompanied or followed by more significant problems such as your screen fading to black just minutes (or seconds) after turning on the TV.

Fading TV screens point to a compromised backlight system. To troubleshoot this issue, some models enable you to “Picture Test” your TV. A “Picture Test” walks you through an on-screen questionnaire to help you determine if the issue is the source (the input, channel, or signal) or the TV hardware.

If your TV’s backlight display is faulty and you don’t have a repair and replace benefit or manufacturer’s warranty, you may have to shell out some cash on professional repairs. Or, you can upgrade anytime with bite-sized payments on rent-to-own TVs from Rent-A-Center.

First, you check your remote’s batteries. Then, you walk up to the TV stand and give the TV’s power-on button a long, hard, angry press! The power light blinks and finally, nothing happens!

It seems like your TV takes longer to come to life with every day that passes. On top of that, the screen makes clicking noises as if it’s straining to turn on. Most of the time, an unresponsive TV screen is caused by a faulty capacitor or power system—which is difficult to troubleshoot and expensive to repair.

If your TV takes forever to start, it may be announcing its impending death, which means you’re better off investing in a replacement than wasting money on a short-term fix.

Poor TV sound quality is a common complaint among TV owners. For some, the issue presents itself as distorted dialogue that’s hard to understand and is accompanied by staticky background noise. For others, poor sound quality means no sound is coming from the TV at all, or that its volume capacity dropped significantly.

Before you ditch your TV, check your audio settings and cable connections. Try plugging in a different set of speakers to test out the sound, too. If all of those check out, it’s time to either replace the TV or supplement it with an epic sound system.

Burn-in, also known as a ghost image, is a faint outline that evidences permanent damage to your TV. This damage usually occurs when the same image is displayed for extended periods. For example, if you always tune into the same news channel—the shape of their logo could become burnt into a corner of your screen.

Burn-in is not fixable, and many manufacturers exclude it from their warranties. To prevent it, you should flip through the channels regularly, avoid leaving your TV on for too long, and enable auto shut-off in your settings.

No DIY or professional fix can purge a ghost image once it sets in. If there’s a haunting shadow on your screen, the best choice is to cast it out of your home and replace that TV with a new, ghost-free one from Rent-A-Center.

It was an accident. The game got really exciting, and the remote just happened to hit the TV. Things just got out of hand, and somehow, your TV screen cracked. Whoops!

A crack on your TV is a problem for obvious reasons: it interrupts your viewing experience and represents damage to the hardware. However, there are less evident yet more concerning reasons to replace a cracked TV:

Most of the time, a cracked TV screen can’t be fixed. Moreover, the health risks of keeping a broken TV around far outweigh the benefits of being able to watch movies through a shattered screen.

If you’re asking yourself, “Should I get a new TV?” The answer is likely, yes. If your current TV lacks the features you need, or you’re experiencing TV issues that are too expensive to repair—it’s time to kiss your old TV goodbye!

Note that if the plasma screen is broken or crashed, it’s not repairable anymore. If this is the case, the TV needs a screen replacement, which may cost you more then the plasma TV itself. (A new screen price is around 2 -3k).

This issue is not repairable and you will need a new screen (PDP panel). That’s why for all those restaurants, bars, and public places, it’s better if you use an LCD type TV, not a plasma.

For example, a Panasonic plasma TV was in a King County bar for 6 months on a sports channel and it developed a burn-in sport channel image. The estimated cost for this type of problem would be $2,500.00. Be smart and save your money!

It is essential to verify if the problem is inherent with the monitor, video card (GPU) or video settings on your computer. A straightforward way to identify this is to connect the computer to a known-good external monitor or TV and ensure that the display cable (S-video, VGA, DVI, HDMI, DisplayPort, USB-C, or Thunderbolt 3) is firmly connected to the video port on the computer and the monitor.

Performance issues may occur if there is any type of damage that is caused to the display cables or the LCD screen.
