lg lcd panel issues price
TV repair costs between $60 and $350 with most spending $207 on average for LCD, LED, plasma, and 4K TVs; costs are higher if repairing older DLP, projection, and HD TVs. TV problems like display issues, powering-on problems, or sound issues can be fixed. Pickup and delivery fees may apply.
For example, the price of a new Samsung 40-inch LED TV is about $400, yet the cost of a replacement display panel for this model is about $380. This price is only for the replacement part and does not cover diagnostic costs, labor costs, or travel or shipping fees.
Unless you are trying to fix a TV from the ’80s or earlier, cracked TV screen repair is not feasible; the entire display panel must be replaced instead. The cost of a replacement TV display panel is more than the cost of buying a new TV, and that’s before labor and other service costs.
TV manufacturers do keep replacement TV screen panels on hand to support products under warranty in case the screen malfunctions, due to manufacturer defect.
If you still want to replace a damaged or malfunctioning TV screen, your best option is to find a used replacement panel or a broken TV of the same model on which the screen is still functional. You might find one on eBay, and you can hire a technician to change out the panel.
The cost of a used replacement TV panel ranges from $50 to $350 or more, excluding shipping, depending on the brand and size. Note that the chances of finding exactly the part you need in excellent condition are slim, and the cost excludes the cost of installation by a repair shop.
Whether your TV is LCD, LED, plasma screen, or 4K (Ultra HD), the cost to fix common problems ranges from $60 to $350, depending on the repair type and the brand of TV being repaired.
If an older model LCD TV or projection TV powers on and has sound but no picture, this may be due to lamp burnout, which is both common and expected. In this case, replacing the bulb will fix the problem. An experienced technician should be able to replace the bulb quickly and easily.
Flat screen replacement glass is not available. The only option for flat-screen TV glass repair is to try optical glass glue, which costs $1.70 for a 5-ml. tube. This may be an option for TV glass repair if the crack is only a few inches or less. TV panels are built as one unit at the factory, with the glass adhered to the display panel.
LCD flat-panel repair is not considered cost-effective. If the glass is cracked or the display is physically damaged, it is cheaper to replace the entire TV than to repair or replace the display panel.
Estimating TV repairs costs by brand is not something TV repair shops offer, however, there are general prices by type. When looking for specific repair costs for your TV, you’ll find them in the common repairs price list above. Pricing applies to brands such as Samsung, LG, Sanyo, TCL, Insignia, HiSense, Sony, Toshiba, Pioneer, and Vizio.
The cost of flat-screen TV repair ranges from $42 to $359. You cannot fix a broken screen, but the price of a new flat-panel TV starts from around $249 for a 1080-mp (non-4K) LED TV from LG to as much as $14,999 for an 85-inch 8K LED TV from Samsung. A TV referred to as a “flat TV” or “flat-screen” TV might be any of the following:
LCD TV repair typically costs $60 to $85 for diagnostics testing, and $200 to $300 to perform repairs. LCD TVs use backlighting, which may fail. Newer LCD TVs use LED strips for backlighting. Older ones might use CCFL. If CCFL backlighting fails, a technician can replace it with LED backlighting.
An LED TV is just an LCD TV that uses LED backlighting, which all newer models do (older models use CCFL backlighting). The cost to replace one LED backlighting strip ranges from $100 to $122, including parts and labor.
Circuit breaker - Check the circuit breaker for the power outlet that the TV plugs into. You can check the breakers by opening the door to your breaker panel and looking for circuit breakers that are in the OFF position.
Lamp burnout -In a projection TV or older LCD TV, no picture may be caused by lamp burnout. In this case, a technician can replace the bulb quickly and easily.
Not included in these prices from Best Buy are 1080P screens, which range from $249 to $279 for 43-inch TVs from brands like Samsung, Sony, and LG. On the upper end, Sony and Samsung both have 95-inch 8K LED TVs for $69,999.
In most cases, a flat-screen TV can be fixed. The exception is a physically damaged display panel or screen. Most other issues including failing speakers, backlights, or power supply. Burned out fuses and damaged input ports can also be repaired.
You cannot replace a broken flat-screen display. New TVs costs anywhere from $249 for a 1080P (non 4K) LED TV from LG to as much as $14,999 for an 85” 8K LED TV from Samsung.
Today, flat screen TVs range from LED and LCD televisions that have been around for a few decades to upgraded models known as OLED and 4K TVs, which boast better picture quality. Plasma screen TVs were once a popular type of flat screen TV. However, they have fallen out of popularity. Most TVs sold today are also smart TVs, which means they can connect to the internet. Older flat screen models that need repair are sometimes not smart. The table below describes these common television types and how much each usually costs to repair.
Repairs for LCD TVs cost between $60 and $475. LCD televisions are one of the most popular options on the market, available in a wide range of sizes and styles. They use an LCD (liquid crystal display) with backlights to produce images. The backlights, screen, and other components may get damaged over time and need repairing. The most common problems for LCD TVs are bad power supplies and dead capacitors that may need repair or replacement.
LED TV repairs range from $60 to $475, depending on the scale of the problem. LED televisions are a specific type of LCD TV that use LED backlights to illuminate the liquid crystal display. These TVs usually produce more colorful and vibrant images and are more energy-efficient, but the LED backlights may need to be repaired or replaced over time. Another common problem is a broken inverter that requires repair or replacement.
4K TV repairs range from $100 to $350. A 4K television provides some of the clearest and most detailed images because of the very high resolution of its screen, providing more engaging viewing experiences. There are different types of 4K TVs, including some that use LED and others that use OLED. Basically, a television is considered 4K if it has ultra high definition. These models can be expensive to purchase and repair, but in many cases, repairs may not be possible on these units. So, their overall repair costs may be lower simply because some repairs may not be offered. Issues that are repairable include inverter, backlight, and power supply problems.
Plasma TV repairs average $100 to $485. These televisions are made up of pixels filled with gas that light up when an electrical current is applied. They are less popular today, and most companies have stopped making them. But they can still be found in many homes and are subject to problems like screen burn and distorted colors. While some repairs on these TVs are possible, such as when the power supply fails, many issues cannot be repaired due to the rarity of replacement parts. Screen burns and problems that require screen replacement render the television not-fixable.
You might not know exactly which part of your TV is broken or damaged at first. The symptoms of a broken television vary from vertical colored lines across the screen to audio issues, power problems, and even situations where the television starts normally but then turns itself off. For this reason, most repairs start with a diagnostic so that the problem can be found and a plan made for repair. For some repairs to be made, the part will need to be replaced, while in other cases, repair or replacement of that part may not be possible. The table below shows common problems and average repair costs for each.
Repairing horizontal lines on your TV costs between $150 and $475. It might be an issue with the motherboard, or it could be a problem with loose cables between the panel and the control board. Sometimes, the fix is as easy as resetting the television to factory defaults or updating the firmware. However, the problem may exist inside the TV, and to fix this issue, the repair person needs to open the television to diagnose the problem.
TV panel repairs average $200 to $2,000 because different types of televisions have materials that vary significantly in cost. An older LED TV might cost between $200 and $400 to fix, but a 4K TV may cost several thousand to repair. Additionally, some panels cannot be repaired. For this reason, many companies do not offer panel repair. So if your television gets a crack in the panel, you may be better off buying a new unit instead.
TV screen repairs cost between $300 and $1,000, but in many cases, repairing the screen is not possible. Since the screen is usually the most expensive part of the television and one of the most sensitive to impacts and other damage, an expert may advise you to simply buy a new television instead of having it repaired. It is worth getting a diagnosis if the screen issue is not too severe because issues like flashing pixels or distorted colors may be fixable. While cracks might not be repairable, sometimes scratches and smudges are fixable.
In some cases, your TV components may not be able to be repaired, or it might be more cost-effective to replace them with new ones. The repair price includes the cost of new parts, plus the labor required to fit them into place and remove the broken components. While some components can be replaced, they may be extremely expensive or cost-prohibitive to do so. This is mainly in the case of panels and screens because they often contain too many parts to replace on their own. The table below shows average costs for a variety of common replacements:
Fuse replacement in a TV costs between $60 and $150 and is one of the easier replacement jobs for a repairman. Glass and ceramic fuses on your TV’s power supply board may blow in certain situations and need replacing. To replace a fuse, the repairman opens the TV to access the power panel and swaps out the fuse. Bear in mind that the TV may have a more serious electrical problem if the fuse blows more than once.
TV bulb replacement costs average $100 to $200. Bulbs are usually found only in older models of LCD TVs or projection TVs. They are used to illuminate the display so that the picture can be seen. Bulbs are relatively easy to replace, but the material costs are a little higher with bulbs when compared to other components, leading to varied replacement prices from model to model. Replacing a bulb can fix a flickering television or a dark screen problem.
TV screen replacement costs at least $400 to $4,200 and may even cost more. The screen is the most expensive part of a TV. So usually, the cost of replacing it is higher than just buying a new unit because of the labor involved. In some cases, this is because the screen cannot be replaced without also replacing most of the other components, particularly for TVs like LED, LCD, or plasma. Most professional repair companies do not offer screen or panel replacement as a service. The only way to get a new screen is to have it fixed under warranty by the manufacturer.
TV panel replacement costs a minimum of $400 to $5,000 and often a lot more on some of the high-end 4K and Smart screen displays. Because the cost of a replacement panel is so high, it is usually more cost-effective to simply purchase a new television. Like the screen, this is due to the number of components involved. Therefore, most repair places will not offer panel replacement as a service.
There are many different brands and companies that make TVs. Some brands specialize in certain types, while others make a wider range of products. It is common for the brand to impact the cost of repair because there may be specific issues or costs related to that brand. While you may choose a specific brand based on the technology, cost, or resolution, keep in mind that brands may also have varying costs for repairs and the repairs types that may be available. Regardless of brand, most TV repairs fall between $60 and $400, although some repairs may be higher.
Fixing a Sony TV will cost you about $60 to $400. This popular brand has a reputation for simply becoming disabled with no power or sound. Unfortunately, the customer service at Sony isn’t always the best. Customers are often frustrated when it comes to warranty work. Sony TV problems that may require repair from a professional include motherboard issues that cause image flickering and HDMI port issues.
Some of the most common issues with this brand are banding at a repair cost of $100 to $200 or sound with a cost of $150 to $400. Color problems may be related to adjustment and can be fixed for a low cost of $75 to $100, HDMI connections are often fixed at the cost of $200 to $300, and streaming problems may be corrected with a software update. Software updates can be done by the owner, but a repairman will most likely charge a minimum fee of $75 to $100. Banding presents as sections of bands where it should be smooth. Sound and color can go out over time in the LG brand. HDMI and streaming can become difficult as technology emerges and changes.
Often, you must decide whether it is worth repairing your TV. In some situations, the cost of repairs is higher than the price of a new TV. For example, when screens are cracked or damaged, the cost of replacing a panel is usually much higher than simply buying a new TV. For major repairs, it is often cheaper to buy a new TV. However, for minor repairs, it is less expensive to call a repair person and get the TV fixed.
It is recommended to replace electronics whenever the cost of repairs equals or exceeds half the cost of a new purchase. It is also recommended that you replace your television if the new version is less than $200, or if your screen is smaller than 32”. For example, it costs around $150 for a new motherboard in an LG Model 24LF452B 24” TV, which takes around one hour to repair. As a result, you would pay between $190 and $210 to repair your old set, while it is possible to purchase a new one for less.
Remote control. A set that powers on and off at random is sometimes caused by issues with the remote. Try removing and replacing the batteries or using a different remote if possible.
Yes, flat-screen TVs can frequently be fixed, including issues with the screen, sound, lighting, cables, and interior components. However, there are some situations where flat-screen TVs cannot be fixed, such as when the screen is severely cracked.How do you fix a broken TV screen?
As you watch your favorite movies and shows, you will want to be able to see everything clearly, and you can do so on an LG TV panel. There are many different choices available on eBay, and there is a wide range of LG TV panel prices. Buying a used display panel is also an option.
There can be many factors that play a role in determining how much a new TV panel is worth. It makes sense that an LG 32-inch LED display panel price may significantly differ from a 64-inch UHD TV. To help you understand the market, here is information regarding features that influence the pricing of LG LED TV display panels:
Resolution: Resolution describes how crisp the image is and refers to how many lines are used to create the image. More lines mean a clearer picture. HDTVs start at resolutions of 1280 x 720, with the term "full HD" meaning the resolution is 1920 x 1080. 4K resolution is either 3840 x 2160 or 4096 x 2160, and 8K resolution is 7,680 x 4,320. An LG LED TV display panel price will likely be higher on the ultra-high-definition models.
Smart ability: Smart TVs are connected to the internet and can be used to stream content or connect with other devices. LG makes dozens of models of smart TVs at a variety of LG LED panel price points. Some models even come with a built-in Google Assistant or Alexa.
On the higher-end models of LG Super UHD TV panels on eBay, there are panels that use nano cell technology. In these panels, nanoparticles are used to enhance the quality of the color, and they also increase the viewing angle of the television. Viewing angles can be up to 60 degrees.
LG makes both OLED and LED televisions. LED stands for light-emitting diode, and it is commonly found in LG panels. OLED stands for organic light-emitting diode, and it is used in certain premium products. OLED pixels are emissive and produce their own light. The resulting contrast is high, and the viewing angle is relatively wide. LED technology is transmissive, and a backlight is used for illumination. LED TVs can be exceptionally bright, making it easy to watch a program in high-light conditions. Models of either type include:
The display makers were accused of fixing prices on LCD panels that they sold to Chinese TV makers from 2001 to 2006. From the total amount of fines, $27 million was paid to nine TV makers as a refund, officials told Yonhap News.
"From 2001 to 2006, six companies involved held a total of 53 rounds of "Crystal Conferences," claiming that they exchange information on the global LCD panel market," an official with the National Development and Reform Commission said, according to Yonhap News. "Those involved turned out to have negotiated prices or manipulated prices, hampering the legitimate rights and interests of other parties and consumers."
A Samsung spokesman declined to comment to Yonhap. But an LG spokesman told the news agency that "to prevent a recurrence of such problems, LG Display has been mending policies and executing them, and remains committed to operating with compliance and transparency."
The decision released on Jan. 4, 2013 in China by the Chinese National Development and Reform Commission concerns LCD panel price-fixing between 2001 and 2006. We do not expect this decision to impact our relationship with customers or panel sales. LG Display remains committed to operating with full transparency in providing the best quality products and services to its global customers.
In 2010, LG, AU Optronics, Chimei InnoLux, Chunghwa Picture Tubes, and HannStar Display were fined around $856 million by the European Commission, which
SEOUL, April 27 (Reuters) - LG Display Co Ltd (034220.KS) saw first-quarter profit plummet far below forecasts and warned of a further drop in panel prices as pandemic-driven demand for TVs, smartphones and laptops fades and competition heats up.
The South Korean Apple Inc (AAPL.O) supplier said it would shift its focus to higher-end products and gradually lower production of more commoditised LCD TV panels where it lacked a competitive advantage over cheaper Chinese rivals.
The LCD TV market shrank by more than 10% in the first quarter and Chinese competitors are pricing their products lower than LG Display"s expectations, Lee Tai-jong, head of the company"s large display marketing division, said on a call with analysts.
"Margins have been squeezed chiefly due to panel price declines and weaker demand, as consumers have already bought many screens during COVID-19 in the past two years," said Kim Yang-jae, an analyst at DAOL Investment & Securities.
The source was not authorised to speak to media and declined to be identified. LG Display declined to comment on client matters. BOE and Apple did not respond immediately to requests for comment.
In the first quarter, prices of 55-inch liquid crystal display (LCD) panels for TV sets fell 16% from the previous quarter while prices of LCD panels for notebooks and monitors dropped by around 7% to 11%, according to data from TrendForce"s WitsView.
SEOUL/TAIPEI/TOKYO -- With windfalls from COVID-19 fading, LG Display is grappling with a record loss as sinking demand, supply chain issues and advancements by Chinese rivals threaten its long-term position in the market.
LG Display said Wednesday that group revenue sank 6% on the year in July-September to 6.77 trillion won ($4.72 billion). Operating loss for the quarter totaled a record 759 billion won, in contrast to the profit of 529 billion won from a year earlier.
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.
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:
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.
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.
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.

Analysts said aggressive marketing by leaders Sonyand Samsung Electronicsin the key North American TV market threatened the market share of LG Display"s client brands, such as Philips, LG Electronicsand Vizio.
"LG Display"s clients will inevitably take a hit from Sony and Samsung"s aggressive price cuts," said Park Sang-Hyun, an analyst at CJ Investment & Securities.
LG Display reported on Thursday a record operating profit in the usually slow January-March quarter, helped by tight panel supplies and surging demand for flat-screen televisions ahead of the Olympics in Beijing in August.
However, chief financial officer James Jeong warned that Sony"s price-driven marketing could affect LCD screen prices and sales in the second quarter.
Meanwhile, shareholder and major client Philips Electronicssaid this week it would transfer its struggling North American TV business to Japan"s Funai Electric, triggering worries that LG Display could lose screen orders for the market.
The LCD TV market is seeing stronger-than-expected demand for small-size sets as consumers switch to sleeker TVs from bulky tubes at ever-faster rates, Kwon said.
South Korea-based LG Display is set to start mass production from its new "eighth-generation" production line early in 2009, when the market is expected to tilt toward an oversupply.
Kwon said the mass production could start one or two months earlier than the original schedule of March or April. "Lots of panels from the 8G line should go to China," Kwon said.
LG Display posted 881 billion won ($903 million) in first-quarter operating profit on a consolidated basis, against a 208 billion won loss a year earlier. Net profit came to 717 billion won against a 169 billion won loss a year earlier.
In the fourth quarter of 2007, Sony jumped four spots to become No. 1 in LCD TV shipments in North America with 12.8 percent market share. Samsung ranked second with 12.3 percent, followed by Vizio with 10.8 percent, according to DisplaySearch.
The history of flat-panel TVs has been written by two fundamentally different technological approaches to creating a TV image: transmissive displays versus emissive displays.
Transmissive displays operate by shining a backlight array through a liquid crystal element. You might know them by their more common names: LCD TVs or LED TVs. Crucially, the light- and color-producing parts of LCD/LED TVs are functionally and physically separate layers. I like to think of the liquid crystal and backlight as the meat and cheese on a sandwich, respectively.
This independent pixel operation (independent from a backlight array and independent from every other pixel) allows emissive displays to greatly maximize contrast and produce richer colors. For example, when an OLED TV needs to display true black in a scene, it just turns those pixels off, whereas an LCD TV needs to find a way to block or turn off the backlight in that area of the screen. This is, in a nutshell, why OLED TVs are special. The ability to produce a true black on such a fine level increases the TV’s contrast (or the difference between the darkest and brightest parts of the image). The high level of contrast in an OLED TV can help your favorite movies and shows look downright jaw-dropping, which makes it an especially good choice to pair with high dynamic range (HDR) content.
As a bonus, because there’s no backlight array, OLED TVs tend to have excellent viewing angles, especially compared to LCD/LED TVs. This means you can watch them pretty comfortably from way off to either side.
Price has been the biggest barrier keeping most folks from having an OLED TV in their living rooms. OLED TVs have consistently carried higher price tags than high-performance LCD TVs—especially at screen sizes larger than 65 inches, where you could expect to pay at least 20% more. And “budget OLED” has never even been a category.
It wasn’t too long ago that manufacturing difficulties and relative scarcity painted a picture of exclusivity for OLED TVs, which kept the price high. While Sony and Samsung were the first to introduce OLED TVs, they quickly exited the market, leaving LG as the only brand selling OLEDs in the US for a time—and in a rather limited array of sizes and configurations. The earliest models had a range of issues, including an odd behavior colloquially called “vignetting” (where the edges of the screen look much darker than the middle), a tendency for darker gray elements to look yellowish-green, and concerns about uneven lifespan expectations among different colors. Those kinks were hammered out years ago, and manufacturers like Sony and Vizio have since joined LG in the US market, though LG Display has been the only company manufacturing the actual OLED TV panels. Yet the prices are still high compared with that of most LCD TVs.
Price isn’t the only consideration, either. OLED TVs are comparably much dimmer than similarly priced LCD/LED TVs. This boils down to operational mechanics: Individually operating pixels, the root of an OLED TV’s strength, can also be a weakness. In emissive displays, turning all the pixels to maximum brightness at the same time can damage the TV. So like plasma TVs before them, OLED TVs use a process called auto-brightness limiting, or ABL. Essentially, as more of the screen becomes bright, the total brightness is automatically limited to ensure safe operation.
In other words, a 2021 OLED TV could only get roughly half as bright as a similarly priced 2021 LCD/LED TV, especially those that use mini-LED backlights. However, it’s important to understand that those brightness numbers are discussed in terms of what’s called “reference brightness,” which describes the general/average light output that you’d notice when watching an OLED TV and an LCD TV side by side. For instance, very bright content that lights up the whole screen, such as a daytime sporting event, will look brighter on a high-performance LCD TV than an OLED TV.
But when considering overall screen contrast—the measure of a TV’s average or peak brightness against its black level, or minimum luminance level—OLED TVs tend to have the best contrast around. Because ABL usually kicks in only when large portions of the screen are bright, an OLED TV’s perceptual contrast (how bright the TV will seem given its black level) is usually much better than that of LCD TVs, especially with HDR content where small, specular areas of the screen are very bright.
However, all that functionality is why it’s important to have control over your room’s ambient lighting if you plan to buy an OLED TV. For example, as much as I love OLED TVs, I don’t have one in my living room—I have a Samsung Neo QLED LCD, which is bright enough to combat the San Diego sunshine that often bathes my home. There’s no point having a beautiful TV if you can’t see it! If you can sufficiently darken your viewing room when you need to, however, there aren’t many TVs that will look better than an OLED.
One other concern that some people have with OLED TVs is the potential for “burn-in” damage, ghostly after-image of content that has been on the screen for an extended period of time. Usually this image retention is temporary, but sometimes it’s permanent. The party line for OLED burn-in is that it shouldn’t occur during “normal” use, and we agree, especially because most modern OLED TVs have pixel-shifting and cell-repair processes built in to ensure that damage doesn’t occur. You can also mitigate burn-in further by lowering your OLED TV’s brightness when it’s convenient. However, if you do watch content with a stationary image (like a news ticker or the heads-up display in a video game) for many hours every single day, you may want to consider getting an LCD TV instead. Ultimately, we think burn-in is only a notable concern for a minor subset of OLED owners.
This year, we’re seeing a few key developments in the OLED market that could help it become a better option for more people. For one, LG and Sony have continued to refine their panels to improve overall brightness, and both are adding more screen sizes to their lineups, including smaller 42- and 48-inch models—which is great for not only gamers but also anyone who just wants a more affordable OLED TV that fits in a modest-sized room. Also, companies like Vizio and Skyworth are selling more affordably priced OLED TVs in the US. (You can read more specifics about the 2022 OLED lines in our guide to the best OLED TV.)
But the OLED news generating the most buzz is that Samsung is returning to the OLED game after almost a decade on hiatus. (Samsung introduced one of the very first OLED TVs back in 2012 but abandoned them shortly thereafter.) The company has a single OLED TV line this year, the S95B Series, but there’s an important caveat: Samsung manufactures its own OLED panels, and S95B TVs have QD-OLED displays, a new variant of OLED. QD-OLED displays combine OLED panels with quantum dots—microscopic nanocrystals more commonly used to pump up the color saturation in the best LCD/LED TVs. Sony also announced a QD-OLED model this year.
Because QD-OLED is brand new, we don’t yet know what benefits or improvements it may offer over LG’s WRGB OLED panels (video) beyond what can be assumed based on the underlying technologies: It should look really good. (We plan to test these new TVs to find out, of course.) The other good news? Samsung has announced pricing for its QD-OLED TVs, and while they’re not the most affordable ones you can buy this year, they also won’t break the bank compared with some of the premium OLED TVs being sold.
On the other hand, it’s too soon to predict how Samsung’s return to the market will affect prices going forward. The relatively approachable price of Samsung’s new QD-OLED model could mean that buying an OLED TV in 2022 is a bit risky. If QD-OLED has better production yields than LG’s WRGB OLED, we could see an entire range of even more competitively priced models in 2023.
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.
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.
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.

Tim, sounds to me like the backlight inverter is going out. You want to definitely check on fuses or continuity of voltage supply lines going to the X Board/s, (your case check the X Board) as well as the LVDS cable. Replace blown fuses, connect broken lines, and resolder loose solders. Check on the capacitors on your boards, they may be either loose or popped. Look for any leakage on the boards (looks like a oily sticky substance) and check the top of the capacitors. they should be flat. Any bulging indicates a failed capacitor, The older LG"s have the backlight inverter power separate from the power supply, and in that case you will require a new LCD Panel. Very costly, if you can even find somebody who has them for sale. The newer LG"s have the inverter connected to the power board. In that case you could try to fix it by replacing the power board. It would be great if besides the model number you could find the Chassis number. It might be possible to get a service manual for you and give you some more specific details for your TV. Hope this gets you started in the right direction. Good Luck.
