I have a AOC 2236Vw, Model TFT22W90PS
The monitor refuses to power on. When I plug the power cord, the monitor's blue power light turns on, then after about 1 second, I hear a faint "tick", and the power light shuts off.
I disassembled, and found "Elite" brand caps. None looked out of the ordinary, but I replaced them anyway, with Nichicon VZ series I had laying around. One cap I did NOT replace, was the orange cap labelled C920, an "Elite GP" series which I couldnt find a datasheet for a suitable replacement.
Replacing caps had no effect.
I also suspected the CCFL lamps may be bad, so I plugged in a couple of spares out of a Dell monitor.
Replacing CCFL lamps had no effect
At this point I'm chasing my tail, I don't know what else to look for. The board is heat-checked around the inverter transformer, but I see no other signs of damage.
This looks like a very common design power supply, and the logic board looks identical to ones out of many threads I've read.
Any suggestions to what I should look for next?
