Shadow areas on screen

Unfortuneately this is a screen display problem that will only get worse, it is possible there may be a bad capacitor in the power supply board.

My AOC screen goes black after about a few seconds after booting.

Hello,

The picture board on your monitor is bad, since it goes off after few seconds and the power led or button is on, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer or service center within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

AOC LM725 LCD Monitor

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!

Envision Series / AOC 22 hdtv monitor

Probably blown capacitors, the 19" widescreen uses 6 16V 1000uF
Do you have a soldering gun? Its not that hard to fix, get the capacitors on ebay for $6-$8 with shipping.

Aoc lm725 display off after few seconds

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.
