I've had a very similar issue on many Dell Monitors. Mine have been under warranty and they usually send me a new monitor, but I believe the issue lies with the power supply within the monitor.

AOC LM725 Monitor Problem


Change the monitor and check if the PC works. If it works then the problem is with the monitor, you will have to send it to repair. If not then, the problem should be with the power supply, check whether all the cables is kept intact.

try looking for bloated caps, check all diodes... see if its not shorted/leaking and finally check the power regulator ic if its not shorted! note: some capacitors and diodes are very tiny, you should use a lens with good amount of light...



if it does not help..... well, what the hell? try pouring some gas, then light it up! that should solve the problem, at least it turned on right? hehehehe!

If some of the pins inside the monitor cable are bent or broken you can losr primary colors and cause this. Check them. If they seem OK try reseating both ends of the cable. If no go, then try the monitor of a differnt computer to see wether its the videocard or the monitor thats defective.
