On Pwr up logo appears then LCD returns to stanby Black screen

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Take it to a repair shop.

Have you tried it on another computer? if not please do it. Your monitor problem seems with the CPU not booting up properly. You can also try with another monitor on the computer. Please confirm after you are done with the results. Thanks.

No input from Video card, try to connect second video cards head to your monitor.

Open up the set and look for bad caps, see example of a couple years old monitors that failed.

More likely to be bad caps in the power suppl;y, see example here: http://s807.photobucket.com/home/budm/allalbums

finwiz,
When you on your computer, does any thing appear on the screen, some text display/logo etc.?
If yes then:

• After making power on your computer start pressing F8 till boot option menu appears.
• Then select safe mode and if it works, then goto device manager and re-install driver for your display.

If no then:

• Check out the connection from monitor to computer and try. If still no luck then post comment whats you did and what was the result.

Thanks

I have exactly the same problem with my Benq FP71E+ ..

What i found is a temp fix is this :

When monitor dims and goes black i turn it off , hit the bottom left side (near the BENQ logo) turn it on again and it works ..

This works every time for me . But after a while it switches off again , could be 5 minutes could be 5 hours . Its random

this monitor having 3 yr warranty
according to the serial no it have warranty till April 2008.

We had the same problem with the 17" we bought in Aug. Sent it back for repair. Acer sent it back without fixing the problem. Started doing it again in Nov. This time I called a supervisor and they sent me a new monitor. Well yesterday it started doing the same thing. You can fix it temp buy unplugging it and holding down the on-off switch for 30 seconds. Please let me know if you have a better fix.

It could be your LCD backlight giving you problems till it warms up. Turn you computer on and while the monitor is displaying black and the power LED is green shine a flashlight in the lower left hand corner of your screen. Look for the ?Start? button, if your backlight is not working you?ll see a faint ?start? button if you look closely. A 15" LCD monitor is probably not an economically repairable problem unless you have access to really cheap parts and have the skills and tools to do the repair yourself.
