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.


There's two fairly common problems with these which I've had good luck
repairing. One is the backlight CCFL tubes and inverter, and the other is
the power supply. Both of these areas can be fixed using basic
troubleshooting with little flat panel specific knowledge.


How do you isolate a CCFL/inverter problem without swapping parts?
I have a panel with a backlight that goes out about two seconds after
power on. Transistor/diode junctions all look OK, no visible cap
problems,
tubes have no telltale black bands. Shorted transformer winding,
perhaps?
How to test for that?

Thanks,
