I've been lurking around for a couple of weeks since my 245bw quietly died and i've yet to see anyone with the exact problem i've had, i tried a few threads including the mega thread and couldn't seem to find any suitable direction so i figured i'd give it a shot hopefully without gravedigging too badly.
So the power supply is a bn44-00173a, that through really quick google searching i decided it'd be best to recap with the kit all 14 caps and the 3 trouble resistors, no luck same symptoms as originally, which happened to be absolutley nothing no blue led no display no nothing i powered off the display one evening due to some lcd burn in had been experiencing this thing never got turned off when i powered it back up about 8 hours later there was no noise, smoke, power led or anything.
i have a meh meter with an even more meh capacitance setting the other common failure items i've read are the 82µf mains cap with i got to measure near that at one point and the 18nf cm802 which i was getting to about 25 nf without removing from the board. Fiddling around with psu and the "mind flatulence" board with the pc connections all connected my voltage reading make no sense basically anywhere 168vdc across cp803 77 into it to gnd and basically 77vdc everywhere else voltage is listed in the diagram so im at a total loss. I do have the 2 main boards and buttons completely off the display due to space restirctions.
