tft lcd color monitor not coming on made in china

one is a hardware fault, the other is a software problem. Although only these two big aspects but involved in the details of the aspect is very much, the following details about the display color abnormal possible reasons and solutions.

Monitor color is not normal, we recommend the first use of the elimination method, as far as possible to eliminate some simple problems. There are many reasons leading to the abnormal display of the display color, such as checking whether the display data line is normal, the display color control panelis not set well, poor contact, or rust of the display wire may lead to such problems.

For this kind of fault a lot of people say that the video card has a hardware fault, some people say that the picture tube was scrapped, and some people say that the driver of the video card was damaged, these views are wrong.

A kinescope-tube failure can cause this problem, but it is not irreparable – minor electric shocks, serious rewound filament power supply windings, and sometimes the visual discharge power supply resistance of a particular electron gun is miswelded or broken or the resistance value is increased.

For the first kind of fault phenomenon, some models only have a certain slight leakage of electricity between the poles, which usually need no maintenance. They only have aninstant color deviation when starting up, which can be normal in a few seconds.

For the contact pole (sometimes only leakage) fault you can only hand it over to professional maintenance personnel for maintenance, its characteristics are usually caused by the protective shutdown. For irregular deviation color fault usually as long as the relevant electron gun visual power supply resistance and peripheral components repair welding can be done.

For the power supply resistance is broken damage caused by the fault phenomenon and contact pole for full screen back sweep wire and very bright color, but it will not lead to a protective shutdown, the solution is very simple – change the same resistance value of the new resistance! Of course, if the resistance value is increased, you also have to do new processing. In the wet season, we also need to take into account the picture tube seat tube oxidation for this reason, although the resulting color deviation fault is not much, but may encounter it.

In addition, there is easier to let people detour the cause of failure – screen dust caused by too much screen white when red! This kind of fault often happens in the monitor that color temperature slants warm (a lot of monitors can set color temperature by oneself), say so, encounter white (and similar color) slants red when the fault you had better be cleaned the first screen later undertake other checks, if the fault disappears, mean you won’t because of this and “unlucky” detour. Of course, too low brightness values on some models can also cause this “fault” phenomenon.

If all of the above methods are ineffective and the display is well over five years old, we can consider the color deviation of the display caused by the aging of the electron gun to be abnormal.

Some half professionals see the two faults as a tube in life, some of the maintenance personnel to see will say adjust the contrast and the focusing extremely potentiometer and accelerate the potentiometer on the ignition coil will be good, others say it’s caused by a hardware failure or graphics driver damage of graphics, these point of failure judgment is wrong.

The aging of the kinescope and the decline, in contrast, will not cause such failure phenomenon, as for the adjustment of the collector and the acceleration of the electrode potentiometer is not correct, this is palliative, and it is difficult to adjust to a satisfactory degree, the most troublesome is that the fault will soon return, even accelerate the aging of the kinescope.

Usually use more than 2 years of the color display will appear this kind of fault, the real cause of the fault is mostly caused by the picture tube seat moisture oxidation, as long as the replacement of the original new tube seat can be troubleshoot. But some say it would be gilding the gilt by using a small piece of sandpaper to polish the protruding end of the tube to remove the oxide. In the picture tube that the author has replaced the tube seat, some of them do have some oxides on the tube foot, but these oxides are missing from the original tube seat to the tube foot, which can be removed with a brush. Up to now, the author did not see the tube was oxidized, but due to excessive force and make the tube leakage and damage the picture tube is encountered a few cases, so we do not use sandpaper to burnish, so as not to appear “death” damage!

If the replacement of the tube seat is not effective will replace the FBT, but in this work, the author suggests you had better find professional personnel! In addition, some types of visual amplifier parts of the circuit are more special, sometimes after the fault will also cause the image blur. But at this time usually the brightness and line, field amplitude are also abnormal, for this kind of fault point the author recommends that you deliver professional personnel to deal with! If the color display is not a brand-name product and the use of a very long time, then the author suggests that you find a professional electrical maintenance department to replace the work of the tube seat, so as to avoid the occurrence of pipe neck leakage and other accidents after the responsibility!

1) the image is clear at the beginning of starting up, but the color of the display is abnormal as the use time is prolonged and the display becomes increasingly blurred;

2) the image occasionally becomes blurry in use, but it can return to normal soon. However, it becomes more serious and frequent after several days or months of use.

Some people think that this kind of fault is the problem of the line circuit of the monitor — it may be the poor thermal stability of the line tube, the reverse diode, reverse capacitor, and other components or the result of virtual welding. This is completely wrong because none of these components can affect the clarity of the image.

The real failure point of the type 1 fault phenomenon is usually due to the aging of the focusing knob of the FBT. You can try to replace an FBT first. Of course, if the monitor has been in use for more than six years, then we need to take into account the possibility of tube aging. In addition, it may be the tube seat of the picture tube and the large area of the negative copper foil leakage phenomenon caused by the displacer (after analysis like design problems), so sometimes into a maintenance dilemma after the replacement of a genuine tube seat try.

The type 2 fault phenomenon, is usually caused by the poor quality of the picture tube holder. You can solve the problem by replacing it with a new one.

A lot of people think this is the mains voltage of the mains electricity is the insufficient or unstable cause, some “master” can say even because of the lamps and lanterns that contains electronic ballast or electromechanical kind electric appliance brings color to show the interference of power source, somebody says the hardware fault that the video card produced is caused by. In fact, these views are wrong, because the display voltage requirements are not very strict – most of the current color display can be in the 100V ~ 240V power supply voltage under normal operation. As for other electrical appliances that will cause interference is even more impossible, after all, color display use is not mutual inductance stabilized voltage power supply, and other electrical appliances even if the interference will not be screen flicker!

The real fault causes of the first two kinds of faults are usually caused by the virtual welding of some components in the line circuit or the reduction of the +300V filter capacitance at the power supply. The latter possibility is not very high – only in a few models and its more serious loss of volume will cause the human eye to distinguish the flicker. In addition, the circuit of the visual amplifier power supply part of some models is special, and sometimes a component of this part may also cause this fault. Of course, if you set your monitor’s resolution and refresh rate too high or too low, you can set the resolution and refresh rate to the middle value.

There is also a video card or monitor driver there are bugs, so you should first update the driver to try. If the above treatment is not effective, you can focus on checking whether the accelerator voltage and high voltage generated by the FBT are normal, because sometimes these two abnormal voltages can also cause such a phenomenon.

The poor contact of the video card usually causes the failure of starting up and there is an alarm sound or the system is unstable resulting in a crash and other failures. The reason for the poor contact of the graphics card is that the gold finger of the graphics card is oxidized, dust, the quality of the graphics card is poor or the baffle of the case has a problem. For the golden finger oxidation caused by poor contact, can use an eraser to wipe the golden finger to solve; For dust caused by poor contact, general removal of dust can be solved; For the hardware quality caused by poor contact, usually through the replacement method to detect, generally replace the video card to solve; For the case baffle problem caused by poor contact, usually the video card can not be fully inserted into the video card slot, can be replaced by the case to eliminate.

Compatibility failure will usually cause the computer can not to start up and alarm sound, the system is not stable crash or screen abnormal miscellaneous phenomenon. Display card compatibility fault generally occurs in the computer just installed or upgrade, more in the motherboard and display card is not compatible or motherboard slot and display card gold finger can not completely contact. The video card compatibility fault usually USES the replacement method to detect, generally USES the replacement video card to troubleshoot the fault.

The failure of the components of the graphics card will usually cause the failure of the computer can not startup, the system is not stable crash, flower screen, and other fault phenomena. The damage of graphics components generally includes the damage of graphics chip, BIOS, memory, capacitance, or field-effect tube. For the damage and failure of graphics card components, it is generally necessary to carefully measure the signals in the graphics card circuit to judge the damaged components. After finding the damaged components, replace them.

Due to the graphics chip will produce a lot of heat when working, so need to have a better cooling condition, if the cooling fan damage will lead to graphics card overheating can not work normally. The overheat fault of the graphics card usually causes the system unstable crash, flower screen, and other fault phenomena. Video card overheating as long as the replacement of the cooling fan.

The failure of the graphics driver usually causes the system unstable crash, flower screen, text image graphics card is not complete, and other fault phenomena. The video driver’s fault mainly includes the loss of the video driver, the video driver is incompatible with the system, the video driver is damaged, and the video driver cannot be installed. For the video card, driver failure generally first enter the “device manager” to see whether there is a video card driver, if not, re-install. If so, but the graphics driver has a “!”, the video card driver is not installed, the driver version is not correct, the driver and the system are not compatible. Generally, remove the video card driver reinstall, if installed after there are “!”, you can download the new version of the driver installation. If you cannot install a graphics driver, there is usually a problem with the driver or with the registry.

CMOS setup failure is caused by the error of displaying related options in CMOS. Common CMOS setup failures mainly include: integrated graphics card motherboard, CMOS graphics card shielding options setting error; For example, the “AGP Driving Control” option is incorrectly set (usually “AUTO”), “AGP Aperture Size” option is incorrectly set, and “FAST Write Supported” option is incorrectly set.CMOS error is generally modified by loading the default BIOS value.

If the fault is serious, the maintenance requires that you must have certain hands-on ability and professional knowledge, so the author suggests that if you still have not been repaired after eliminating the simple cause of the fault, please deliver it to the electrical maintenance department for treatment. Sometimes some magnetic objects (such as some low power box or ADSL cat power supply, etc.) placed near the display will cause a certain Angle flicker on the screen, so when this phenomenon to try to clear the display around the objects to see, usually the problem can be solved.

Troubleshooting CRTs versus LCDs begins with similar steps, but diverges due to the differing natures of the two display types. The first troubleshooting steps are similar for either display type: power down the system and display and then power them back up; make sure the power cable is connected and that the outlet has power; verify that the signal cable is connected firmly to both video adapter and display and that there are no bent pins; verify that the video adapter is configured properly for the display; try the problem display on a known-good system, or try a known-good display on the problem system; and so on. Once you"ve tried the "obvious" troubleshooting steps, if the problem persists, the next step you take depends on the type of display. The following sections cover basic troubleshooting for CRTs and LCDs.

CRTs seldom fail outright without obvious signs, such as a loud snap or a strong odor of burning electrical components. Most CRT problems are really problems with the power, video adapter, cable, or hardware/software settings. To eliminate the CRT as a possible cause, connect the suspect CRT to a known-good system, or connect a known-good display to the suspect system. It is worth noting, that older CRTs eventually wear out, and starts dimming. Common signs of a weak CRT are a dim picture, dysfunctional brightness and/or color controls, image smearing at high brightness, and in color CRTs, a tint towards a single color (Red Green Blue)

If the CRT is the problem, it is often not worth repairing. If the CRT is out of warranty, parts and labor may cost more than buying a new CRT, which also gives you better specs and a warranty. About the only CRTs we"d even consider repairing out-of-warranty are high-end 21" or larger models, and even there the economics are dubious.

Even if the CRT is in warranty, the shipping costs may exceed the value of the CRT. For example, shipping a CRT both ways can easily cost $75 or more. If that CRT is a year-old 17" model, you"re probably better off spending $100 to $200 for a new 17" or 19" CRT than paying $75 in shipping to have the old one repaired. CRTs have many components, all of which age together. Fixing one is no guarantee that another won"t fail shortly. In fact, that happens more often than not in our experience.

Never disassemble a CRT. At best, you may destroy the CRT. At worst, it may destroy you. Like televisions, CRTs use extremely high voltages internally, and have large capacitors that store that energy for days or even weeks after the CRT is unplugged. Robert once literally burned a screwdriver in half when working inside a color television that had been unplugged for several days. Also, the large, fragile tube may implode, scattering glass fragments like a hand grenade. People who repair CRTs and televisions for a living treat them with great respect, and so should you. If you must repair a CRT, take it to someone who knows what they are doing. You have been warned.

Check the obvious things first. Verify that the CRT is plugged in (and that the receptacle has power), the video cable is connected to the video card, the computer and CRT are turned on, and the brightness and contrast settings are set to the middle of their range. If none of these steps solves the problem, your CRT, video card, or video cable may be bad. Check the suspect CRT on a known-good system or a known-good CRT on the problem system.

CRTs contain multiple filaments, which can be broken, or gas may have leaked into the vacuum inside the CRT. CRTs damaged this way are unrepairable without specialist equipment. With the display open. check if all three filaments are glowing bright orange. Excessive redness or purple arcing signifies gas has leaked in. There may also be an internal short inside the CRT, which is also unfixable without specialist equipment.

If you have ACPI or APM power management enabled, it may be causing the problem. Some systems simply refuse to wake up once power management puts them to sleep. We have seen such systems survive a hardware reset without restoring power to the CRT. To verify this problem, turn off power to the system and CRT and then turn them back on. If the CRT then displays an image, check the power management settings in your BIOS and operating system and disable them if necessary.

The horizontal and/or vertical deflection system has failed. The CRT tube itself is fine, but the circuitry driving the tube has failed. Replace the display.

This is a hardware problem with one of the electron guns. Replace the CRT. This problem may also manifest as a strong color cast during normal operation that is not correctable using the normal color balance controls.

Catastrophic CRT failure is imminent. The noises are caused by high-voltage arcing, and the smell is caused by burning insulation. Unplug the CRT from the wall before it catches fire, literally.

There are two likely causes. First, you may be driving the CRT beyond its design limits. Some CRTs display a usable image at resolutions and/or refresh rates higher than they are designed to use, but under such abuse the expected life of the CRT is shortened dramatically, perhaps to minutes. To correct this problem, change video settings to values that are within the CRT"s design specifications. Second, the power receptacle may be supplying voltage lower than the CRT requires. To correct this problem, connect the CRT to a different circuit or to a UPS or power conditioner that supplies standard voltage regardless of input voltage.

This is usually a minor hardware problem. The most likely cause is that the signal cable is not connected tightly to the CRT and/or video card, causing some pins to make contact intermittently or not at all. Verify that no pins are loose, bent, or missing on the cable or the connectors on the CRT and video card, and then tighten the cable at both ends, If that doesn"t fix the problem, open the computer, remove the video card, and reseat it fully.

In elderly systems, another possible cause is that some hardware DVD decoder cards "steal" one color (usually magenta) and use it to map the DVD video signal onto the standard video signal. Remove the DVD decoder card. If your video adapter includes hardware DVD support, or if you are upgrading to such an adapter, you don"t need a DVD decoder card.

The most likely cause is that the CRT is receiving inadequate power. Connect it to a different circuit or to a backup power supply that provides correct voltage regardless of fluctuations in mains voltage.

The most likely cause is that the refresh rate is set too low. Change the refresh rate to at least 75 Hz. Flicker also results from interaction with fluorescent lights, which operate on 60 Hz AC and can heterodyne visually with the CRT. This can occur at 60 Hz (which is far too low a refresh rate anyway), but can also occur at 120 Hz. If you"re running at 120 Hz refresh and experience flicker, either use incandescent lighting or reset the refresh rate to something other than 120 Hz.

Most modern CRTs can display signals at many different scan frequencies, but this doesn"t mean that the CRT will necessarily automatically display different signals full-screen and properly aligned. Use the CRT controls to adjust the size and alignment of the image.

Depending on the CRT, video card, and video settings, this may be normal behavior, adjustable using the CRT controls. If the distortion is beyond the ability of the controls to correct, the problem may be with the video card, the CRT, or the driver. First try changing video settings. If the problem persists at several settings, move that CRT to a different system (or use a different video card) to determine whether the problem is caused by the CRT or video card. Repair or replace the faulty component.

This is usually caused by RF interference from another electrical or electronic device, particularly one that contains a motor. Make sure such devices are at least three feet from the CRT. Note that such interference can sometimes penetrate typical residential and office walls, so if the CRT is close to a wall, check the other side. Such image problems can also be caused by interference carried by the power line or by voltage variations in the AC power supply. To eliminate interference, plug the CRT into a surge protector. Better still, plug it into a UPS or power conditioner that supplies clean power at a constant voltage.

This problem may also be caused by using a video cable that is too long or of poor quality or by using a poor-quality KVM switch (keyboard/video/mouse switch). Manual KVM switches are particularly problematic.

The CRT may need to be degaussed. A CRT that sits in one position for months or years can be affected even by the earth"s very weak magnetic field, causing distortion and other display problems. Exposing a CRT to a strong magnetic field, such as unshielded speakers, can cause more extreme image problems. Many modern CRTs degauss themselves automatically each time you cycle the power, but some have a manual degauss button that you must remember to use. If your CRT has a manual degauss button, use it every month or two. The degaussing circuitry in some CRTs has limited power. We have seen CRTs that were accidentally exposed to strong magnetic fields, resulting in a badly distorted image. Built-in degaussing did little or nothing. In that case, you can sometimes fix the problem by using a separate degaussing coil, available at RadioShack and similar stores for a few dollars. We have, however, seen CRTs that were so badly "magnet burned" that even a standalone degaussing coil could not completely eliminate the problem. The moral is to keep magnets away from your CRT, including those in speakers that are not video-shielded.

An incorrect yoke may have been attached to the CRT. Unless you have a lot of spare time on your hands, this is usually not worth fixing. Replace the display.

If your LCD displays no image at all and you are certain that it is receiving power and video signal, first adjust the brightness and contrast settings to higher values. If that doesn"t work, turn off the system and LCD, disconnect the LCD signal cable from the computer, and turn on the LCD by itself. It should display some sort of initialization screen, if only perhaps a "No video signal" message. If nothing lights up and no message is displayed, contact technical support for your LCD manufacturer. If your LCD supports multiple inputs, you may need to press a button to cycle through the inputs and set it to the correct one.

Unlike CRTs, where increasing the refresh rate always reduces flicker, LCDs have an optimal refresh rate that may be lower than the highest refresh rate supported. For example, a 17" LCD operating in analog mode may support 60 Hz and 75 Hz refresh. Although it sounds counterintuitive to anyone whose experience has been with CRTs, reducing the refresh rate from 75 Hz to 60 Hz may improve image stability. Check the manual to determine the optimum refresh rate for your LCD, and set your video adapter to use that rate.

First, try setting the optimal refresh rate as described above. If that doesn"t solve the problem and you are using an analog interface, there are several possible causes, most of which are due to poor synchronization between the video adapter clock and the display clock, or to phase problems. If your LCD has an auto-adjust, auto-setup, or auto-synchronize option, try using that first. If not, try adjusting the phase and/or clock settings manually until you have a usable image. If you are using an extension or longer than standard video cable, try connecting the standard video cable that was supplied with the display. Long analog video cables exacerbate sync problems. Also, if you are using a KVM switch, particularly a manual model, try instead connecting the LCD directly to the video adapter. Many LCDs are difficult or impossible to synchronize if you use a KVM switch. If you are unable to achieve proper synchronization, try connecting the LCD to a different computer. If you are unable to achieve synchronization on the second computer, the LCD may be defective. Finally, note that some models of video adapter simply don"t function well with some models of LCD.

If the screen is displaying a full, stable image, but that image is of poor quality, first verify that the display is not connected through a KVM switch or using an extension cable. If so, connect the display directly to the video adapter using the standard cable. If that is already the case, adjust the brightness, contrast, and focus controls. If you are unable to get a proper image using these controls, the problem is most likely a clock or phase mismatch, which you can cure by taking the steps described in the preceding item.

The best way to adjust clock and phase is to use auto-adjust first. Check the utility and driver CD that came with the monitor. It may have a wizard or at least the appropriate background screens to use while adjusting phase and clock settings. If not, go to the Windows Start menu and select Shutdown. When the screen goes gray and the Windows Shutdown dialog appears, leave that dialog onscreen, but ignore it. Use the gray screen to adjust clock and phase manually. Any problems with clock and phase and any changes you make to the clock and phase settings are clearly evident on the gray screen.

Always adjust clock first. Clock is usually not a problem if you have used the auto-adjust feature of your monitor, but if you do have clock problems they will be evident as large vertical bars on your screen. Tweak the clock setting until those bars disappear. Then adjust phase. Phase problems are evident as thin black lines running horizontally across the screen. Adjust phase until the lines disappear or are minimized.

Not all analog video cards synchronize perfectly with flat panels. The gray Shutdown screen exaggerates the problem, so don"t worry if very tiny movements are visible after you"ve adjusted clock and phase as well as possible. After you"ve set the clock and phase controls for the best image possible on the gray screen, cancel Shutdown and the image should be optimized.

Your video card is supplying a video signal at a bandwidth that is above or below the ability of your LCD to display. Reset your video parameters to be within the range supported by the LCD. If necessary, temporarily connect a different display or start Windows in Safe Mode and choose standard VGA in order to change video settings.

This occurs when you run an LCD at other than its native resolution. For example, if you have a 19" LCD with native 1280x1024 resolution but have your display adapter set to 1024x768, your LCD attempts to display those 1024x768 pixels at full screen size, which physically corresponds to 1280x1024 pixels. The pixel extrapolation needed to fill the screen with the smaller image results in artifacts such as blocky or poorly rendered text, jaggy lines, and so on. Either set your video adapter to display the native resolution of the LCD, or set your LCD to display the lower-resolution image without stretching the display (a feature sometimes referred to as display expansion), so that pixels are displayed 1:1, which results in the lower resolution using less than the entire screen.

This is a characteristic of LCDs, particularly older and inexpensive models, caused by defective pixels. Manufacturers set a threshold number below which they consider a display acceptable. That number varies with the manufacturer, the model, and the size of the display, but is typically in the range of 5 to 10 pixels. (Better LCDs nowadays usually have zero dead pixels.) Nothing can be done to fix defective pixels. Manufacturers will not replace LCDs under warranty unless the number of defective pixels exceeds the threshold number.

Some people claim that leaving the unit powered off for a day or two will "erase" a persistent after-image. Others suggest leaving a neutral gray screen (like the one used for phase adjustment) up on the screen to "equalize" the display. I dunno. FWIW, I"ve seen this problem on older Samsung panels but never on the Sony or NEC/LaCie panels I use.

Again, this is a characteristic of LCDs, particularly older and inexpensive models. The after-image occurs when the display has had the same image in one place for a long time. The after-image may persist even after you turn the display off.

Transistor-based pixels in an LCD respond more slowly than the phosphors in a CRT. The least-expensive LCDs exhibit this problem even with slow image movement, as when you drag a window. Better LCDs handle moderately fast image movement without ghosting, but exhibit the problem on fast-motion video. The best LCDs handle even fast-motion video and 3D gaming very well. The only solution to this problem is to upgrade to an LCD with faster response time.

Use the brightness control to increase image brightness. If you have set brightness to maximum and the image is still too dim, contact the display manufacturer. The CCRTs used to backlight the screen have a finite lifetime and may begin to dim as they near the end of their life.

If one or more horizontal and/or vertical lines appear on the display, first power-reset the computer and display. If the lines persist, run the auto-setup function of your display. If that does not solve the problem, power the system and display down, remove the video cable, and verify that the video plugs and jacks on both computer and display ends do not have broken or bent pins. Even if all appears correct, try a different video cable. If the problem persists, contact the display manufacturer.
