Emerson plasma clicks about 4 times but won't start up. I have replaced the power board with a shop jimmy one with no change. I have tried unplugging various board with no change. I do get a green light on t con while it's trying to start but clicks off when power board does. What is my next step?

PSU: EAY63168603
PCB: EAX65359531 2013.11.01 Rev:1.0
Main board: EAX65399305(1.0) 13.11.27 PU42A/PA42A/PD42A
Symptom:
While watching, just went black and started clicking relay every few seconds.
Initial diagnosis:
Removing JUST the main CPU/Input PCB from circuit stops the clicking. No problems with any other boards/drivers. (Removing all other boards and only putting Main back in is all it takes to start clicking again)
Deeper diagnosis:
Pulling pins #1/#2 (Blue/Grey) from the connector housing... -
by SiskoHi all!!
Ok just got a Onkyo SKW-593 sub woofer that has no power person told me that it smoked and that his GF let the volume full when she powered off the amp and when he came to turn it on the sub played but then suddenly smoke was coming out, didn't say from where. So opened it up and saw a resistor made of metal (pic) but can't see any writing on metal par so what ever was written on it was burnt. So I'm kinda stuck here with this. I did ask for a repair or schematics in the other group section and waiting for this but I hope someone here might lend me a hand to try and identify...4 Photos-

Symptoms:
The TV turned itself off, and I haven't been able to turn it back on. The standby voltage was unstable and lower than it should be.
A weak clicking sound was coming from the transformer.
Video with clicking sound:https://www.youtube.com/watch?v=lAduhjNtqCA
Progress:
After the transformer, I measured four Schottky diodes. DM862C and DM864C diodes readings were 003 in both directions. After detaching them from the circuit and measuring them, DM864C was the shorted one. These Schottky diodes are SB550.I... -
by novak2Hello there,
I recently bought a Panasonic th-42px60en plasma TV second hand. The problem is :
The TV takes time to turn on from cold (being unplugged from the night for example), it tries to turn on with the clicking sound, then shuts off, then retries and so on. The TV is still working, just it takes time to boot.
From what I've read it seems to be bad capacitors on the power board, but I just want to see if anyone had the same problem with this TV.
Thanks in advance. -
by estabilitoHi, I've just repaired acer nitro an515-55 with specs:
i7-10750h, rtx2060.
Laptop had damaged cpu and after replacement came back to life but i have weird problem with this machine.
After night or 2-3hours on first startup laptop shows acer logo, windows circle for second and then screen goes blank - machin stays on but i need to turn it off by holding power, on next startup laptop working just fine.
i've tried different bios, different vbios and same behaviour - clean windows install too.
Do you have any idea?08-13-2025, 02:52 PM - Loading...
