Re: Panasonic TC-P42S1 10 blinks, bad SC maybe solved.
Do you have any IGBTs from other Panasonic Sc boards spare, like dg502, rjp63f3a etc?

Roughly 5k. I also got new needle probes today and they take a bit of getting used to.------------signature starts here------------

I just remembered I have a TNPA5066AC in my scrap box. It's got a couple of the parts I need. I haven't checked them yet though.------------signature starts here------------

Re: Panasonic TC-P42S1 10 blinks, bad SC maybe solved.
It does. Not enough though. Funny thing is that I have all the bad components marked on it. I guess I was going to try to fix it at one time. I'd have no way to test though, so I guess that's why it's in the scrap bin.------------signature starts here------------

Re: Panasonic TC-P42S1 10 blinks, bad SC maybe solved.
Yes, it would be hard to fix without a run up. i blew my first attempt, got it second time around. Still have one here to paly with but i already have sn x 2 and ss x 2 for the tv spared, don't fell like pulling it apart now that it's used.
might as well just order what you need thenComment

Re: Panasonic TC-P42S1 10 blinks, bad SC maybe solved.
Yeah, plus, I'll someday get another TV which takes that board and then I'll fix it and be able to test it. My policy is not to sell anything which I can't test. Although, that doesn't always mean 100% tested. In the case of a broken screen, you can only partially test. But to perform a complex repair and then not test, that is an absolute no.------------signature starts here------------

Looks like I'm going to have to spend some hours cross-referencing parts. Wish there were a cross-reference database somewhere.------------signature starts here------------

Re: Panasonic TC-P42S1 10 blinks, bad SC maybe solved.
Ok, everything is on order. All from China so this will be on hold for about a month. I ordered 20 of everything so I am good for a few tries. If I got it right, I might add this to my short list of boards I do exchange services on. I will post back when the parts are all in.------------signature starts here------------

Hi there,
It does not look like anyone with the 10 blanks error code ever had their TV fixed.Comment

Re: Panasonic TC-P42S1 10 blinks, bad SC maybe solved.
Yes we have!
Ive done a couple--Its just that they are a right Pain in the Ass, and need SO many parts to do, because of the way the circuits are designed causing all the driver and other parts to fail!
--They certainly aint a quick fix or particularly easy even for a well experienced engineer.
If you (as you say) a newbie, it may be best to just buy replacement SC....TELEFIX

Alastair E, thanks for your reply. Are all the Mosfet Transisters bad on the SC board? I saw a repair kit on eBay.Comment

Re: Panasonic TC-P42S1 10 blinks, bad SC maybe solved.
I'm still waiting on parts for mine. I guess I ordered just before the Chinese New Year, which is evidently a month or more. Well, as much stuff as they produce in a year, they deserve a month off.------------signature starts here------------

Re: Panasonic TC-P42S1 10 blinks, bad SC maybe solved.
lookimback, When you power on the TV does the fans spin up then stop? (My TC-P42S1 fan does not spin up at all).
The two yellow shaded diodes are shorted. Any ideas?Attached FilesComment

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 here🤔?
Ok Im a mechanical engineer ...but I thought I was able to follow a rather simple flowchart for electric troubleshooting 😂.

Bought this TV used not working, panel flashed briefly on power up and it was blinking 8 times, a quick look on SS board revealed a common fault on the 3uF 250V capacitors, C201 to C205 (C1620X in the service manual), the solder joints were all cracked, C201 and C205 pins were darkened and some sparking had occurred on them, C201 was split open and clearly overheated in its last hours, replaced that one and resoldered the others, 8 blinks fixed.
Also the previous owner broke the antenna connector by taking the TV out of the wall mount forgetting to unplug it, I desoldered the tuner... -
Hi,
anyone able to provide the service manual for old plasma Panasonic TX-P42ST50E?
It turns off almost immediately (0~5 seconds after pressing the on/off button) and starts flashing the red diode 6 times.
I disconnected the left-hand side board (SC?, both the ribbon cable and the power cable to it) and also another ribbon going to bottom left board. Then the led signal is 8 flashes. According to service guide to another Panasonic plasma it would mean the left-hand side board is faulty. But I'm not sure it 100% applies to my model.
I checked that board for any obvious faults... -
Hello,
Stopped by this site trying to fix my parents Panasonic Plasma TV.
Model number is TH-50PZ85U
Power comes on and the red power light stays on solid.
Did a few checks like hold the power button on for 60 seconds, hold the - Volume while holding the menu button, no luck, still@ blank grey screen as the screen lights up very vague.
I also hear a few clicks.
I also think my parents said there was a thunderstorm and the TV failed after that.
Section 6 in the service manual talks about power and no screen,...10-30-2024, 10:09 AM -
Hello all,
As the title states, I followed the troubleshooting guide located here: https://www.manualslib.com/manual/23...page=53#manual, which concluded the 'A' board needs to be replaced. Looking around the net and eBay, I see that there are repair services for the board (TNPH1043UE? Not sure if it is a 'UE' as the suffix grid does not appear marked). What additional troubleshooting can be performed to ensure 1) this board is the problem and 2) since there are repair services, what are they fixing on the board?) I expected 3.3V not to be available anywhere...
