My daughter was watching our TV when she said it made a couple clicks like when you turn it off and off it went, not to come back on again. I was out of town but had them try the obvious stuff like plug into another outlet, etc.
When I got home I tried a few things, and found the fuse fine & that plugging in the set did draw a little current, although there was no response at all from the on button. I wondered if maybe the micro was getting confused by high ESR caps around it, but found none that appeared to be bad.
I searched for this problem and found some people saying to just change out the PS switchers Q601 & Q602 and R607. Some suggested also changing the HOT. I checked all solder joints under the microscope and found no bad ones.
From your experience, what would you suggest? I prefer to change parts on purpose rather than shotgun, but without a schematic, I'm not sure what voltages I should be seeing before the set powers up. At this point I'm presuming the power supply quit, but would like some opinions from those that know more about this than I do.
