One common failure in some designs is a chain reaction failure. PoorWhat fails most commonly in inverter circuits in, for example, 18 inch LCD
displays?

I know anything *can* fail. But is there a common, high-frequency failure
component in these inverters?
Thanks.
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.
