You may want to check out those caps on the top left of the board and the two at the bottom of the board by the 4 inverter transformers first. Failed caps are the most common problems in the LCD monitors and LCD TV.

First place to check will be the caps in the power supply/inverter board.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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.

Dell228wfp on start up pwr on is green screen


Either the cable is not connected to the proper port or the display-source is not configured properly.Here's what you can try.
  • Ensure that you have connected the VGA/DVI cable in the correct port. If you have an extended graphics card in your computer, use a DVI cable(Digital input) else the VGA would be the only option available.
  • If the cable seems to be plugged at the right place, press the first button from the left on the front panel of your monitor (Button 1 shown in the front view: http://support.dell.com/support/edocs/monitors/E228WFP/En/ug/about.htm#Front_View), once. This toggles the digital mode to analog mode of your monitor, and vice versa.
  • If the first two steps do not work, its not an issue with the monitor. It could be a failing cable or a defective video card, or the system itself is not completing the POST.

Thanks,
Abhishek

mark587, Did you shine a very bright flashlight 1" from the screen to try and see the WIN-desktop ?? Even though the screen appears BLACK. Your words above said: JUST CAN'T SEE IT Did you really NOT see anything? Have you seen any of the longer video clips of "LCD Monitor Disassembly" on YOUTUBE? Some BLACK screen "symptom" lcd displays can be repaired for less than $10 in parts. Capacitors! Also check videos on lcd repair. Then get back here to fixya and I or any of the guys can help you decide what to do with your display whoose screen is now dark and lifeless. After doing the YOUTUBE thing you may even tell us what you will do!!! Hope this was helpful. Yes we do want to hear back from you. please rate this response on fixya. I'm louie12fix on fixya or lmistyrel @ aol.com. Bye for now.

ViewSonic 19" flat screen monitor goes black - intermittently


Hi,
There could be a problem with your display card settings or the display card itself. If you are using Windows operating system, make sure that you have the monitor driver installed for that specific monitor. This is to ensure that Windows only allows settings for which your particular monitor was designed.
Let me know if I can assist you any further regarding this.
Best wishes,
Graemevm

Kds model 780 monitor no signal, power button does not work


My monitor does the same thing at times and sometimes shows "No Signal" and at other times the screen will maintain the images but the backgound color switches to mustard yellow. In each of these cases I have been able to solve the problem by unplugging the power cord from the electical outlet for about three seconds and plugging it back in. I have a KDS model 780 LCD.
GOOD LUCK
