Hi everyone I have a plasma here that is absolutely dead no power light. When I press the power button the relays click the fan spins for a second then it's dead and nothing happens on the screen. Anyone have any suggestions?

I'm starting to believe it may be the power supply? -

Re: Panasonic TC-P50G10 DEAD
Well it appears I can spend $200 on a used good sc board or spend like $70 on a repair kit for the sc board. I think I will just have to throw in trash if not economical to repair.Comment

Damn what a shame.Comment

Re: Panasonic TC-P50G10 DEAD
Yep and that just confirms it every where on the interwebz you here of people replacing like $200 in boards to still not have it work well sorry but this one unfortunately is going in the e-waste bin.Comment

Re: Panasonic TC-P50G10 DEAD
Not totally e-waste, you can disconnect the SC board and test if everything else works, remove the cable from P-Board to SC and the flat from A-board to SC, it should come on with no image but green light, VSUS, Vda and VE on the SS board.
The A board has some value plus the power supply.Comment

Re: Panasonic TC-P50G10 DEAD
there are "used boards" on aliexpress for less than $100. I guess it depends on the gamble. Probably limited overall value at this point in the technology. I guess it would depend on its history / abuse.Comment

Re: Panasonic TC-P50G10 DEAD
Ya and who knows what else is wrong with it plus im trying to flip these tvs and if I can't fix it economically for re-sale I can't do it.Last edited by Super360; 12-28-2021, 03:03 AM.Comment

Re: Panasonic TC-P50G10 DEAD
If it helps; here is the service manual for it:

It's actually impressively comprehensive.

Hello, got a ST50 plasma TV for repair. No signs of life, not even blink codes. Opened it up to check the power supply, type MPF6914. Apparent issues from visual detection and measuring for shorts:
Diode type G972s6 - D101 with a short
Mosfet 06N90E - Q301 shorted
Fuse T5AH 250V - F103 blown
Diode D301 shorted
Relay DG1U-17VDC II - RL001 blown
I have not found a circuit diagram. Maybe someone here already dealt with a similar issue? Thanks for tips where else to check π... -
Hello! yes I know there is already lots of information about this issue. I have a Panasonic TC-P55ST50 that originally displayed an 8-blink error code. Following the troubleshooting flowchart, I ended up replacing the SS board. However, even after replacing it, the issue persists. The TV turns on and stays on without displaying an image, and continuity is confirmed on all connectors. What am I missing hereπ€?
Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting π.

Hi all,
As the title suggests, how can I be sure that my EC chip is really dead?
I've recently gotten into this hobby of laptop repairs, and have successfully brought back to life a couple with some easy fixes, mostly shorted caps.
Now I'm working on HP Probook 455 G8, that had some "devil" run around on 3V line, burning a bunch of stuff. Luckily I have a dead 455G7 (for spare parts) so I managed to fix it (swapped burned parts) to a point that it will charge (both on barrel jack and usb-c), but it doesn't want to turn on. There is a 3V3 on a keyboard... -
Hello. I am asking you for a hint on how to solve the problem with my touchbook Panasonic CF53-2 standart model. After setting up the BIOS, the laptop displays the wrong image until Windows loads. (More precisely, it displays, but distorted, instead of the Panasonic image immediately after turning it on, it displays what is in photo #1 in the attached file) Then the image appears when Windows starts loading and then there are no problems with the screen until the reboot. If you enter the BIOS, just a black screen. If you connect an external screen, the image on it is the same as on the built-in... -
Hi guys!
I searched for the term "dead short" in the forum but no specific thread came up however if I'm just blind and couldn't see the thread talking about this please forward me to that direction.
So my problem is I don't know how to find the source of a dead shorted voltage rail. Dead short = ~0 ohm resistance.
I have two VGAs (HD 4850 and HD 4870), both dead shorted to ground on the memory rail. I have the boardview file for the 4870 and the memory rail consists around ~7892346 capacitors...
I have a bench PSU and if I try to inject voltage the voltage...
