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?



I have a few lamps and inverters that are not in monitors, it's pretty easy
to wire one or the other up for testing without tearing things apart too
much.
