Hi everyone, I hope you are all enjoying this holiday season.
Samsung PN64D7000FF not coming on
I have a Samsung PN6400D7000FF plasma that will not turn on or do much of anything. When I plug it in I get 6 flashes of the standby light but if I press the power button I just get a brief flicker and nothing happens. There is no audio, video, backlighting or clicking.
When I plug it in I get one click, no repeat clicking like I would expect from bad caps. The logic board has a green LED that comes and goes, lighting for 5 seconds followed by 1 second of off.
The power board does not have any bulging capacitors and all outputs show the prescribed power on my meter.
I have tried booting it with the X/Y boards unplugged and nothing happens still.
When I use the remote the standby light flickers for as long as I hold a button, but the tv still never comes on.
I have looked over every board and flexed them as much as I was comfortable with to test for a broken solder, but I'm out of my wheelhouse here so I don't know what else to do.
Do you think I should try replacing the main board? I don't want to throw parts at it if there are further tests you guys can recommend.
Anyway, that's what I'm working on. Thanks in advance for any assistance you can offer here. I really appreciate it!
