Default What fails in CCFL inverters?

One common failure in some designs is a chain reaction failure. Poor
quality caps are used in the power supply and the inverter. As the
ESR rises the drive transistors in the inverter tend to overheat,
eventually shorting and blowing the input fuse on the inverter.
Replaceing the low quality caps, the transistors, and the fuse results
in a working monitor.

The Westinghouse Westinghouse L1975NW (and equivalent Acer model) -
identical monitor except for the plastic - have this problem.

In case anyone watching was wondering, this is what I was looking for.
Knowing what *might* be the modus operandi of this monitor is a huge leg up
on the attack for a non-pro such as myself.

Thanks, PB! And to all the others who pitched in.
