Hi All
It's officially Panasonic week here at JRElectronics LOL I've received five in a row, one repaired and four left. I don't normally even repair TVs but it's bad PR to turn away the work, I'm the last shop left in town. Besides, I like Panasonic and I like plasmas, I wish more people would buy higher quality stuff and have it repaired when it breaks.
This one won't turn on, no lights at all and no flash of screen.
Measuring 5V STBY it's only 4.5V so I moved up to the PFC circuit and it's only 169V. Those PFC caps are rated at 450V I would have thought I'd get 385-400V there. Does anyone agree?
Would it be a good guess that if I fixed the PFC so that it's 400V I'd get 5V back on the STBY and the set would work?
Any help appreciated, I've downloaded the manual but Panasonic used a Hitachi power supply "P" board in this one so there is no schematic, just a block diagram.
