Noob here. Some electronic experience. I am working with a TH-58PX600u 10 blinker - pre power button. None of the TP's on the PA board are shorted to ground. All fuses good on the P-board. Ran through the trouble shooting guide and it seems to be coming from a faulty P-Board, it has bulging 900uf 220v caps 2 of the 3. Removed them from he board and they all meter ~854uf. I am getting around 34vac from the top of all four 220uf 450v caps on the P-board. Found that by accident. I shouldn't be seeing voltage from the top of the caps right. Any ideas?

Watch https://www.youtube.com/watch?v=LjpGKaBt8hg and follow all of his steps.
You actually only need to replace the ceramic capacitor next to the IC.Last edited by tom66; 01-26-2013, 06:55 AM.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Panasonic TH-58PX600U 10 blinks
You can determine if those are the problem using freeze spray as he showed in the video, so I'd recommend you try that. I've got no experience with this chassis myself.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Panasonic TH-58PX600U 10 blinks
They are not the issue apparently. I used the spray to cool the ic's but still received the 3 clicks and 10 blinks. I also tested by freezing both at the sametime and all individually. Why would i be seeing vac from the top of the caps??Comment

Re: Panasonic TH-58PX600U 10 blinks
Can I see an overall shot of your PSU?
The top of the capacitor is sometimes connected to one terminal or is sometimes floating to an internal node.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Bottom of the board, near the brown cap, across from the white-on-black DEC relay would be my guess.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Panasonic TH-58PX600U 10 blinks
I am looking at that stand-up board which may be the cause of your 10 blink code. Try freeze-spraying it to see if it sorts out the problem.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

OK, try with the A Board disconnected.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Panasonic TH-58PX600U 10 blinks
Removed PA connections from the P-Board, no change, 3 clicks 10 blinks.
Removed SC connections from the P-Board, no change, 3 clicks 10 blinks.
Removed SS connections from the P-Board, no reaction, no blinks or clicks.
Removed D connections from the P-Board, no reaction, no blinks or clicks.
Make sense?Comment

Maybe this training manual will help.

Re: Panasonic TH-58PX600U 10 blinks
Although they look bulged, that would be very rare on this chassis. It's very nice to the caps and they're pretty good caps too. 10 blinks is a PA board failure, not Vsus failure - that would be 4 blinks.Please do not PM me with questions!

Re: Panasonic TH-58PX600U 10 blinks
If you can get it cheap enough, otherwise, there is a schematic of it I think, so it can be diagnosed.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

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 😂.

by BiruslapioBought 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... -
by jm1234Hi,
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... -
by AlicatHello,
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... - Loading...
