Hi there. I posted this on Reddit but couldn’t get much help so I’m trying here. I have this plasma TV (Samsung P60E550) from 2012 that I love and something in it got fried this January, funny smell and everything. I sent it to repair and apparently a board was replaced and it cost me 400 CAD. Recently I went to turn it on and again I see what I think is the same behaviour with the LED, which is a pattern that would go beep-beeeep, beep-beeeep if the light made a sound. No popping/clicking or burning smell though. Since it's past the warranty of the repair place I am trying to give it a go at it myself. I've opened it up and I can't spot any blown-up capacitors. Here's a picture of it, open: https://imgur.com/a/5ihJwtn I tried disconnecting each board to study the behaviour of the device and I made these notes:

- when only the power board is fed (the one at the centre) = LED is off. (makes sense since power is fed to it via the main board)

- when only the power board and the main board are fed - meaning, the power cable that feeds the left and right boards is disconnected = the LED flashes 5 times and goes off.

- power board + main board + right board only (power cable that feeds the left board is disconnected) = the LED does 1, 2, 3 long flashes, one short flash and another long flash, and it goes into the loop of "beep-beeeep, beep-beeeep" that I described above.

Any ideas on how I can isolate the issue? The image of this TV is still great, it has the 3D feature that I wouldn't want to miss on (yeah, I know, I'm one of those people lol)...

Thanks for any help.

Hi tame

Cool we share the same tv and unfortunately a similar problem. I’m also tryna diagnose it myself, have you had any luck in the past year fixing it? I suspect it’s the main board
