Monitor problem, it turn-off in few minutes

would appear the system is in standby mode you could disable this
in windows 7 or vista go to
start
control panel
power options
choose when to turn display off

Look at the top of your keyboard. One of the function keys has one or two icons on it that look like little monitors. Turn on your laptop let it have a fewe minutes to get going then press the "Fn" key at the same time you press that key if it does not work press it again, your screen should come back on one of the times you press them. If it does not then you have worse problems....

please check the monitor or LCD that you have. because the computer will not flicker if there is a problem on the display. isolate it. use other monitor or LCD then check if it flickers again.

1. You can see images on the screen for a few minutes. That means there is nothing wrong with your computer.

2. When your screen goes blank, if you disconnect and then reconnect the monitor, it shows fine again for a few minutes before going blank (or dim) again. That means the problem is not with you video card.

3. It always shows the image after reconnection for exactly a few minutes before going blank again. yes? this means that there is nothing wrong with your cable.

Conclusion: Sorry, but you do not have many options. I bleieve that the problem is with your monitor that's going bad. Its far cheaper to get it replaced than to repair it.

This is an indication that the power board in the monitor is bad.

Try reseating the Graphics card first..It may be loose. Or try it in a different slot.

look at the screen held in a bright light at an angle do you see the desktop dimly .
if not try the function monitor key,
connect an ext monitor to verify the video card is working ,fn monitor .
if you see the desktop dimly then the inverter may be out or the lamps.

Can you see the whats on the display but just seems the background lighting is off?

make sure that the audio wire connected to the your monitor is fine or try 2 replace it and also makesure that the wire ome the main power which is connected 2 the switch or pc is fine and if necessary replace it i hope it works

it would seem that one of the internal components has failed / overheated Dont open the rear of the monitor !

if pos drop it into your nearest pc repair shop and have is serviced it may just need cleaned to free it from dust build up
on the inner parts this may be causing the unit to over heat
