Vizio VX42L HDTV10A not coming out of standby

Re: Vizio VX42L HDTV10A not coming out of standby

I'd have to say I'm guilty of swapping a component out on a hunch but it usually would either have the same symptoms of the previous failure or simply be a matter of having the part in front of me so, what the heck, change it. For me personally, being a field systems tech (vs. a bench tech) for so long, I'm not where I'd like to be with component troubleshooting without schematics. If I have a schematic, I'm ok - just ok, lol.

I've worked in both worlds. When I worked on TVs schematics were usually available, and the circuits were functionally very similar. I moved to electronics production where schematics, parts lists, and parts were readily available, but the type of failure was radically different. Locating solder shorts is an art in itself. TVs have progressed to the point where it can take hours to analyze a circuit. Even if schematics are available, tracing a signal line across three pages of a PDF is more of an exercise in frustration than instructive. And schematics for many subassemblies are unavailable.
