Re: panasonice tx42s31b 8 blinks
8 blinks -- SS board or SC board. Do you get an LED glow on SC? See training manual.
(for 3D model - maybe 2D model manual available elsewhere - should still be usable.)Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: panasonice tx42s31b 8 blinks
I can't see any LED. There is a repair kit available which involves replacing all 7 surface mount FETs, maybe try checking them for shorts.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: panasonice tx42s31b 8 blinks
So the green light does still light, no red flashes? I'd be hedging a bet on the A board. Maybe tw2005 has a better idea.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: panasonice tx42s31b 8 blinks
disconnect sn2, restart and see if that produces a blink.Comment

Yes 7 blinksComment

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... -
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 😂.
TV Model: Panasonic TC-P55ST50

Does anyone have an idea of what might be the issue with my 3050 micro? I have tried replacing new cmos battery but still the same
I am not sure if its the powersupply that I'm using is the issue since its the original powersupply. its a laptop powersupply with the same specifications with the 3050 micro so i guess it should be fine.
i also tried replacing the bios but with no avail, everytime i try another bios it gives a different blinking lights
Any recommendation on what I have to do next? Thanks in advance -
Hi I'm new to trying to repair TVs, but I saw a broken OLED offered for a reasonable price and thought I'd try my hand at it.
I found the service manual, which was critical to know where to probe.
https://www.manualslib.com/manual/20...1e-Series.html
With it I was able to determine that my DKA board was bad, when P_ON#1/2 gets enabled REG_12 on the DKA board collapses. I'm assuming one of the downstream regulators has a short, but I couldn't work out which rail/component and replaced the DKA board entirely.
Unfortunately the 5-blinks... -
Greetings friends,
I have a Panasonic TH-42PX75U manufactured in 2007. It has been trouble-free until recently. One evening I turned it on and it then powered back off and gave 7 blinks.
First a question about the blinks. Everyone only speaks of a single number of blinks. I noticed on my TV, it blinks one fewer times for the first group of blinks, then blinks the full number repeatedly. So for my first code in question, the TV switches off, blinks 6, then blinks 7 repeatedly. When I disconnected the SC board, the TV switches off, blinks 7, then blinks 8 repeatedly....
