Power supply section will be the first place to check.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Screen blank green light flashing slowly


chriswowe359

Normally when the power light is flashing green on the monitor this means that the video drivers are having problems.

Note with LCD monitors they are very picky about the signal that they get and if they get a signal that they can not support they will go black to keep them from burning out.

The best way to fix this issue is to connect a CRT monitor to your computer and reboot the system. After you reinstall the video card driver you may need to also install the actual monitor drivers for the monitor. Note in most cases the default Windows driver will send the proper info over to the monitor but in this case that driver is where the problem is and updating to the actual driver will help keep this problem from happening again. The link below will show you how to update the monitor driver in Windows 7.

How to install your monitor drivers in Windows 7

If you still have trouble or do not have access to a CRT monitor you may want to try the monitor on another computer. If it works then you will need to back up your data and reinstall Windows on your computer.

Let me know if you have any more problems or questions

Monitor L17AMTN flashes WinXP desktop, then blanks.


dmellman, Before you open it up, try this! With fully booted pc and WIN DESKTOP screen up, reconnect the L17AMTN . Have a bright flashlight handy so that when the lcd screen flashes on for 1 second and then goes dark, you will want to check to see if the desktop remains on the screen even though you think it went away. Shine the light 1-2 inches from screen at different angles. Has the desk top completely disappeared or is it still being displayed? Do you know about Cold-Cathode-Fluorescent tubes and their Inverter type power supply? I assume that this unit also has a "lay on floor black box switch-mode-power-supply" that is supposed to supply raw 12v-14v dc to the monitor? This symptom is typical of lcd monitor power supply failure, and or inverter board failure. Not to mention the fact that the CCFT's could be a bit tired from use. YOUTUBE has some videos on taking apart lcd monitors. also do search on web for "bad caps on lcd boards" or "bad caps in lcd monitors". I should think that this Tatung might suffer from swollen cap-itis. get back to me with results of your investigation. Im louie12fix on fixya or [email protected] just nrth of Windy City

No video output from my computer.


Are you using an ON-board graphics adapter or a separate VIDEO CARD? Some motherboards lets you set the video output to "DISABLE ONBOARD GRAPHICS" if you have installed a video card (BIOS). You may have plugged the monitor cable to the onboard D-sub connection instead of using the Video Card D-sub connector.

Normally a flashing green power light means the input it receives from the video output is too much. You may have set the resolution too high or the bit depth too high. Consult the monitor manual on the rates it can handle. To be safe, try starting the computer on safe mode just to check if it is indeed the problem. If it boots properly and you can see your desktop, then there's a chance that the setting was too much for the monitor to handle.

Hope this gives you an idea.

BLANK MONITOR


the signal stage of your monitor is likely to have a problem, if the cpu is working fine then troubleshoot the signal stage of your monitor or visit a local technician
