Hello,

Can anyone point me towards some websites which can be of
help when dealing with lcd monitor repair.
Schematics, panel reference lists, repair tips, troubleshooting...
Any help would be welcome as google wasn't so helpful.

At least 8 out of 10 LCD monitors I see have power supply, or back
light inverter problems.

The most common power supply problem is defective caps. Poor quality
caps are finding their way into everything now. The bad ones will
have the tops bulging out, but it's usually best to replace them all
if a few are bad.

The inverters are more complicated to fix. Any number of things can
go wrong. I see bad transformers, shorted transistors, shorted
diodes, and bad caps. No schematics are available and the SMD
components are often not marked in any meaningful way. I have
repaired a lot of them, but it often requires doing a lot of research
to ID parts. Once thing you can check is the tiny surface mount fuse
on the inverter board. When they are blown, about half the time
there's nothing else wrong. Fortunately, the inverter is the one
board that can sometimes be replaced for a reasonable price.
