Re: Panasonic LSEP1287 4 blinks
no, the x20 may have components the same but uses sc/sd/su boards. yours is all in one SN. Just because the screen is cracked, does not mean those SC boards are good and I find often the buffer boards (SD) are blown from TVs with cracked screens that have been powered on.
Done any deeper fault finding on the board?Comment

Re: Panasonic LSEP1287 4 blinks
quick testing with components still soldered to board:-
D451 - shorted both directions - diode test function on multimeter
D441 - OK
IC771 - appears ok
D503 - shorted
D536 - OK
D522 ok
D534 ok
Q701 ok
D701 shorted
Plus the three pther FETS shorted.
I think this is uneconomical to repairComment

Re: Panasonic LSEP1287 4 blinks
Hi been were you are with one of these. the parts are not expensive less than £15.00 most you can get over here in uk (eBay all SMD parts on here ) the bigger parts if you can wait I buy from China (www.utsource.net) if you order on line they will be with you in about 10-12 days. I buy in bulk just had some parts today ordered on the 8/1/15. There are some posts that are tagged to a TW thread that will be of help to you, showing the parts that I replaced to fix my TNPA 5066 board, It was not all plain sailing as you will read but could be of help.

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...
