Re: Panasonic TH-50PZ80U 7 blink
Ok my new su and sc arrived today, hooked everything back up and I still get 7 blinks, so assuming (yeah I know) that my new boards are good. I unhooked the sd and ran the cha jumper. about 1/4 of the screen now comes on, so I guess the sd is bad as well even though it tests as not shorted. Anything else I should look for before I order a new sd?

Looks like first time setup menu to me... before you order SD, try entering analogue TV or doing test patterns (refer to service manual for instructions.)Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Panasonic TH-50PZ80U 7 blink
I will give that a try when I get home. Just curious though it won't start with both connected. I unhooked the SD to get to that point. That's a relief though as I couldn't find any buffer failures that looked like mine. I also noticed the manual says the d board can cause 7 blinks as well. But that shouldn't be the case because it goes away with the SD unhooked.....correct?Liberating magic smoke one part at a timeComment

Re: Panasonic TH-50PZ80U 7 blink
Ok hooked up an analog source and this is what I get with the sd unhooked cha jumper in place.I couldnt get into the service menu without the remote, may dig out a universal and program it in for this tv.

Re: Panasonic TH-50PZ80U 7 blink
It looks like at least some of the buffer board connections are loose. You may have bad SU and SD?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Panasonic TH-50PZ80U 7 blink

Re: Panasonic TH-50PZ80U 7 blink
Got my new sd today, after many many resetting of the ribbons we have a good picture.
Thanks tom, Just an fyi for anyone with a similar model the top of the screen wouldnt display anything until the sd was replaced.

Re: Panasonic TH-50PZ80U 7 blink
Well the owner was coming to pick up on sunday, so I plugged it in to show them it was indeed fixed and it gave me the 2 blink error......Doooooh. I opened it back up and froze mc301 and it started up. So I replaced the small mlc shown in other threads, and once again it works. My question for tom, the other threads used a 1uf 50v cap. Does anyone really know the value of that cap, it seems so tiny to be rated that highly. I replaced with an electrolytic on extension wires. But if in the future if I run into it I would like to have a couple mlc's on hand. Long story short happy customer in the end.Liberating magic smoke one part at a timeComment

Re: Panasonic TH-50PZ80U 7 blink
It's likely 1uF/16V. I have used caps that small (0603). In fact you can get 10uF/10V in 0603 size, which is pretty high density.
Interestingly, the fault of 2 blinks usually gets slowly worse and worse, so it probably exhibited that problem beforehand.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Panasonic TH-50PZ80U 7 blink
When I talked with them about the smoke residue inside they told me they inherited it along with another LCD tv.... neither one worked. So they wanted to get the big one fixed, it may have the other trouble for awhile and just waited to rear its ugly head when I thought I was done. I will order a few of those mlcs just for good measure I'm positively dumbfounded that they shoehorned that much capacitance in that itty bitty little capacitor.Liberating magic smoke one part at a timeComment

Re: Panasonic TH-50PZ80U 7 blink
Multil layer ceramic capacitor technology has come pretty far. About 20 years ago you'd be lucky to fit 0.1uF/16V into something that size and there's now talk of a 22uF/10V coming out in 0603 in the next few months. They're pretty reliable, I'm not sure why the ones on these Panasonic boards die so often.
Did you do both MC-module boards? One causes 10 blink and the other causes 2 blink.Last edited by tom66; 09-23-2013, 04:23 PM.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

No I just did the one, hopefully the other doesn't die soon.Liberating magic smoke one part at a timeComment

If it does come back with 10 blinks before power button is pressed you know where to look.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

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 -
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 — 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... -
Years ago my tv gave a 7 blink code which turned into 8 during diagnosis. I had ordered a replacement ss board but somehow the tv started working again and i never used the board. Now a week ago my tv flickered and shut off at random and gave the 8 blink error code. The same issue it had all those years ago. The only difference this time is that over the last few months there has been some purple and green tinge that comes and goes in more solid colors such as white.
Anyway i checked all the screws and replaced the ss board with a known good one and still got 8 blinks. I saw a... -
Greetings from SoCal I am new to this forum but not new to forum world. I come from Automotive end of side which is my main passion in life. Give the automotive nature, I love fixing and restoring things and I have in the past fixed many simple electronics, soldering, etc.. but this is a bit more involved so I found this forum, and I am very glad I did.
I picked up a Panasonic TC-P60VT60 with the 7 BLINK error.
Upon removing the back plate I found spider webs, dead spiders, and an amazing amount of dust. I did my best to clean the surface of the boards with a portable vacuum... -
I aquired this Panasonic 60" plasma around the time my first child was born. It was meant to be a project tv, hoping to fix it chipping away at the repair in my free time. Well that was 2 years ago and i'm really just getting around to making a sincere effort to see if I can ressurect this beast.
The symptoms of the tv ar as follows:- Plug AC in to back of TV
- After about 2 seconds the relay on the P-sub board will click on and then a fraction of a second later it clicks back off
- The 3 blink code is given by the power LED
- If the TV is unplugged and then
