The picture board on your monitor is faulty or bad, since
black after few minutes, it means the
board of your monitor has developed fault.
The best thing for you
do now is to take the monitor to a local repairer within your vicinity
to help with the replacement of the picture board or any service center
because the fault is not something you can fix yourself. in order not to
victorash02, Is screen black n blank, or just black? Do flashlight test! Yes it could be both! Most likely problem with unit's internal "switch-mode-power-supply"/"CCFL inverter supply". You or technician will need to investigate for probable cause of black screen of death. Need a little history of unit! Did it work just fine 2 weeks ago? How many "ON" hours of use on the unit? When was it made? Did you PROVE that PC not cause and works ok? Get back here with more info so we can help.

We have the same model of monitor and had the same problem few days ago. The monitor just goes black/turns off. I noticed that the power button has a yellow blinking light and cannot be turn on/off again using the power button. The CPU is working fine also. When I turn off the avr, the power button's light turns blue for a few second and you can hear a click sound from the back of the lcd before it totally turns off. My lcd monitor is over a year old now and is 110v or 220v capable. Mine was originally in a 220v, i just put it in 110v and the monitor was fixed.. Hope this can somehow fix your problem.
Sounds like a bad solder joint on the printed circuit board. Once it heats up then it no longer makes good contact and the monitor goes black until it cools down and makes contact again. You could resolder it if you knew where it was but monitors are dangerous to go playing around with as they can hold very high charges of electricity in their capacitors that are very dangerous. It's a throw away world. Go buy a new one.
Please reduce the resolution/ Frequency of your Display Card in system and see whether you can see some thing. Else connect this monitor to another system with low resolution. Let me know your feedback.
While it is sounding like a hardware problem. I'll throw in my 2 cents. Have you check the cables from the power to the source and from the monitor to the computer. Just make sure those aren't loose.
One other thing...you mentioned you turn off the computer "afterwards" then it fixes itself. Is the fix for longer than it turns on at first? or does it stay on longer then goes out?
Let me know what happens.
