Im a novice in electronic repair. just researching here n there about what i need to fix. My AOC got power on/off cycle. Learning from few articles, and a book, I found s push/pull transistor (C5705) shorted and replaced it. I also replaced C945 and A733 transistors and /A431 IC. Now it did power up but only display Red Green Blue, White and Black color cycle continuously. Im suspecting an IC labeled SC68410Z KA23500506C, or something like that but can't find it from the shop I frequent. Any help out there?

Is the power cord plugged in all the way? Try a different power cord if you see no indication of power. If that doesn't fix it, you might have a bad power supply. Electrolytic capacitors in the power supply are a common failure component and it might be cheaper to repair than to replace. I am a repair technician and was able to repair my two AOC televisions for less than $3 by replacing 4 electrolytic capacitors. You will need to pay a technician for parts and labor.

I diagnostic flowchart manual to solve the problem but It will not fit in this limited space. If there is some way to send it let me know. You will need to know how to work on electronic circuits to use it. It could be boards P, A, GS,K ,GH
No, all you need to do is reset the monitor to factory settings. I fixed mine that way. If your monitor goes off every 3 seconds (like mine did) you have to be fast or siwtch it on/off few times between the steps to get it fixed.
- 1st. unlock the OSD if when you press 'menu' you get the message 'OSD Locked'. To do this switch off the monitor, and press 'menu' while you switch it on again.
- 2nd. Switch it on, press 'menu' and quickly 'press '<' (left) twice and 'menu' twice to get it reset.
- 3rd switch it off and on again and if still goes off after 3/4 secs, try to reset it again.
I reset mine and it is working find. Before it went blank after 3 secs.
I just tried this because I did not understand why if it was a hardware problem I could see the screen for 2/3 seconds and if pressed on/off it came back, it made no sense as a hardware 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!
