Re: TH-P50G15A - 6 Blinks- Bad TNPA4782
on diode mode im getting 0.535, and 1.105

Re: TH-P50G15A - 6 Blinks- Bad TNPA4782
just looking over the first board info I posted again.
D652 is that ok. Maybe throw a new IC691
My resistance is nothing like yours across 10-20 for those buffer ICs,ic561,562.
mine starts in the meg ohms decreasing slowly as it charges.
So I tried diode red on 10(gnd) = 0.484, Blk on 10(gnd) 0.968Leave a comment:

Re: TH-P50G15A - 6 Blinks- Bad TNPA4782
I'm getting something like 169K on both those ICs pins 10-20. The thing is I plugged on the SC board with Sc50 shorted. It'll sound like the SC turns on for a second (starts buzzing) and then goes off and then it'll start blinking 6 times.Last edited by Glitcher; 04-11-2015, 03:36 PM.Leave a comment:

Re: TH-P50G15A - 6 Blinks- Bad TNPA4782
out of curiosity what resitance do you get across pins 10-20 on either ic561,562?Leave a comment:

Re: TH-P50G15A - 6 Blinks- Bad TNPA4782
Ok I feel like im going crazy here... I remeasured Q660 and its not shorted now... I could of sworn I went over it twice and my meter beeped on continuity... I need a break =/
Also I haven't replace IC 691 yetLeave a comment:

Have you replaced ic691 yet?Leave a comment:

Re: TH-P50G15A - 6 Blinks- Bad TNPA4782
Well going through all the IGBTs again I just found Q660 is short... I didn't replace this one yet since it wasn't shorted the first few times I went over it.Leave a comment:

Re: TH-P50G15A - 6 Blinks- Bad TNPA4782
yep, I realise but we may be chasing a non issue if your meter reacts different.
I get about 9.5k in either direction and there's a 10k rsistor across where we are testing> I don't think we can get clear picture of what's going on and I can't see where to go next or if i's worth the timeAttached FilesLeave a comment:

Re: TH-P50G15A - 6 Blinks- Bad TNPA4782
So I guess I'm fine without those traces? Explains why it would peel off so easily I guess.
I just have a regular meter I bought from some electronics store.
Maybe it was the diode you used?Last edited by Glitcher; 04-11-2015, 09:52 AM.Leave a comment:

Re: TH-P50G15A - 6 Blinks- Bad TNPA4782
I took my opto out still same unless this is just how your meter rolls? What do you have?Leave a comment:

I recently got my hands on a 60" Panasonic P60ZT60 plasma tv (european model) that has some strange issues along with an 8 blink code.
It know this tv is getting old but it was once considered one of the best plasmas ever made, and i think it is still holds on to that even by todays standards.
So, long story short. When i first got the tv it had a very bright washed out picture with very raised blacks in all picture modes and i couldn't find the cause in the picture setting menus.
After doing a factory reset this problem was gone and the picture was back to...01-06-2025, 06:02 AM -
I write this to maybe help another with this TV.
So I aquired this TV a 2023 model. It started the 2 blink reboot problem which indicates bad panel. It was still under warranty and the repair man came by.
The Samsung repairman brought a brand new panel and switched my original boards to the new panel. The new panel then had the 2 blink error code. The repair guy said he has seen this and the MAIN board on this model will cause the 2 blink. He then replaced the main/power board (they are both connected) and put it back onto my original panel. Voila it worked.

Hi everyone,
I'm new here and trying to repair my Panasonic TX-P50V10E plasma TV, which is currently showing the 6 red blink error code.
Just for context: I'm used to building PCs and installing modchips in old consoles, but this is my first time trying to fix a TV. I'm French, and while my English is okay, I'm using ChatGPT to help translate and clarify my messages as much as possible â so please forgive any odd phrasing.
I'm also not very experienced with using a multimeter, but I'm very motivated and ready to follow instructions carefully and report... -
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... -
đđģI recently got a tx-pr42gt30, I bought it in non-working condition. When I opened it, I saw that all the transistors and diodes had been removed from the tnpa5330, and several microcircuits were in poor condition, so I decided not to try to repair it. Instead, I bought another tnpa 5330 (also AB), which was already repaired (according to the seller, the board was repaired and worked before the screen was damaged), transistors were also changed on it, but Chinese copies were installed (there is no round hole in the middle, the inscription is easily erased) and a pair of transistors that...07-19-2025, 07:53 AM
