Its not receiving a signal from the video card or the resolution is out of range for the monitor.
assuming you have the correct PC input selected on your monitor and not on scart or RGB?
Plug your PC into another monitor, see if that gets a gignal, if so then ists most likely one of the other two causes, and you should reduce the machines resolution or refresh rate down to 1024x768 AND 60hz
try again on you plasma, then take it back up to a comfortable resolution and refresh. if it dissapears again, wait it should revert back to previous setting if you do not confirm you can read the screen ok.

if it doesnt come on on another monitor, check you dont have two video cards. and use the other socket.

Hello,
The flashing power light and very slow display is an indication that the internal power supply board is failing. This is usually caused by bad filter capacitors on the board. You should be able to repair the unit by replacing the bad capacitors.

Hp flat panel monitor comes on shows logon and then blank screen


Ok, another words, monitor powers up for few seconds and shuts down by itself. If green LED on the front panel turns off as well or stays on?
If stays on, then inverter turns into protection mode because of old backlight lamps.
If it turns off in same time with an image on the screen, then there are some bad electrolytic capacitors in the power supply.

When i turn on my monitor it shows my desktop then shuts off after 10 seconds...never stays on


elainenemeth, Hi, Tell me more! How old is this LCD monitor? Is it out of warranty? Did the "SHUT-DOWN-IMMEDIATE" problem occur without warning? Did the BenQ display a "perfect" image the day before? Did you actually count----1001, 1002----1010 and then it shut down, after pushing the monitor on button. Did you do the "flashlight" test? With monitor connected to a "known-good", fully booted pc with Win Desktop displayed, TURN ON the monitor! Did it display the desktop for 1-2-10 seconds ? What did you see or not see when you pointed the flashlight at different angles about 1-2" inches from the now dark (black) screen? Get back to me with your results. I will offer the best advice possible to you as a consumer/user of LCD/FPD monitor. I'm louie12fix on fixya or lmistyrel @ aol.com Bye for now.

Monitor flashes on then goes black.


I think you have the display shut off. the button on the bottom left will shut screen off. It will come on for a few seconds if you touch the screen, but will shut off again. just push the display button again and it should stay on.
