Sharp LC-32AD5e-BK, Sharp LC-26AD5E-BK

OldLes:
Some time ago, I had a quick look at a 26" sharp. Plug in, wait a few seconds, relay clicks and green LED lights up. Nothing else at all. It was in rather tatty shape, so I pulled the boards and junked it.
Today a pal brought me the 32" equivalent set, with identical fault. I recall problems with touch buttons, so unplugged the lead to the panel, but it still did the same with no response from remote.
I searched here, and found an apparently identical fault reported under LC-32AD5E, with "fault found, F404 O/C".
Needless to say, F404 on both this and the board pulled from the 26" set were OK.
I shall try to get to the bottom of this one, as the set is very tidy, but it does seem to be a common symptom, so has anybody got any suggestions to point me in the right direction.

Isn't this the same if not very similar to the Orion set that had so much trouble playing dead ? Sure there's a couple of threads  about what to replace on them might be worth a read

Hi Les,

Is the inverter working?

This when you need a ccfl tester!

Failure of sharp ccfls is or was common, some sets also have an error count which stops the set working and needs to be reset in the service menu. It has been a few years since I have seen a sharp so a search on the net may throw up some info.
