Repairing several AOC LM923 computer displays... a schematic, anyone?

I've some computer monitors without power that need fixing. Who has a list of common problems & quick fixes for these guys? Or where can I get a schematic for them? Changing Caps doesn't do anything this time. Everything appears perfect... no dry joints even. Any clues?

Wow! That's awesome :-)

Thanks... eternally grateful is an understatement :-)

How do you even go about getting hold of this sort of info? I could have saved so much time if I had schematics & service manuals for everything I was asked to fix instead of drawing them out for myself first!

Help me out like this any more & I'll have to put you on a payroll here ;-)


It's all good. That is what ifixit is all about. Helping each other out fixing things....


You, sir, re-define "helping"; or maybe you just believe in ‘going the extra mile’? Either way, very much appreciated :-)
