Our TH-50PZ700U just died, was new in Dec 2007. At first it started messing up the picture with 1/2 image 1/4 blank and 1/4 gibberish then yesterday I got 10 blinks and none of the suggestions here worked.
I cant complain to much, it has been a great TV, and the girlfriend lives in front of it and seldom turns it off, so we probably have at least 12 or more hours a day on it since 2007.

I have been working with electronics for 30+ years so I called Panasonic to ask what board I need to fix this. They claim that ONLY authorized service centers can give out that info and buy parts from Panasonic to do the repair.
I see used boards for sale on eBay, but I don't want to spend $150 for something that may die also.

So does anyone know which board(s) causes the 10 blinks, and where can I buy them new, to install myself?
I need info soon before the girlfriend makes me go out and buy a new set

We are back in business
Following the links you provided, it pointed to the P board (Power Supply) I found one on eBay for $150 and that did the trick
Thanks for the help

Unhappy Bought a 54 inch Viera... got it home... 8 blinking lights

I live in Ottawa Canada, and after doing a bit of research I heard that the Panny Viera was the next best thing to the late - great - Pioneer Kuro.

I did my research and found that there was a $700 price difference between the ones sold in Canada and the ones sold in The USA.

I drove down to Massena New York and pre-ordered one from Sears. After waiting two weeks, I excitedly drove down (1.5 hours) and picked it up.

When I got it home and plugged it in... I heard "click click" and then the power light flashed 8 times. I unplugged the HDMI cables in the back and now I'm letting it sit overnight. I'll try again in the morning by plugging it directly into the wall but I'm a bit put off.

There's no warranty once you bring it over the border, but I'm sure that Sears will be cool (since I picked it up yesterday).

Should I just take the refund and get something else?

Try turning it on with nothing connected and see if you can see the TV menu. If you can try using a different HDMI input to see if it is one bad input. What are you connecting and to which HDMI input? I remember there is an issue when connecting a computer to the Pannys that you must use the HDMI3 (the side input) for some reason having to do with frequency timing. Were you connecting a computer as the input source?

If it is not that simple change then I would exchange it but don't be put off. Panasonic historically has the best reliability record for a few years. Unfortunately even the best mfg have a few lemons. It is impossible to avoid with mass production unless we all wanted to pay much more for everything.

I would not tell them you took it over the border though. Maybe try the replacement in the store before making the drive again. They may have gotten a bad batch but it is very likely just a fluke single lemon.

Also make sure you do NOT transport it laying down flat and keep it standing upright for the drive home. These have glass screen panels and there is a reason they say to keep them upright and WHY glass transport vans have mounts holding the glass panes upright when they bring glass to job sites.

Hope this helps & welcome to the forum!

Bad batches do happen though.
Just a bit unlucky. I have a 42, 50 and 54 Panny. Never a problem of any kind ever. I just purchased a Sammy LCD. Great picture if you sit directly in front of the set. Otherwise, crapola. It's going back.

But thats just me. Plasma rocks.

My Panny just died. My brother-in-law and I each bought one of the TH-50PZ800U models a year and a half ago and now they both have the 10 blinking lights of death. We started experiencing the problem around same time (within a few days) of each other. We live several towns apart.

I was able to keep it going a while by taking the advice here and moving hdmi cables around, pulling them all out, and unplugging and plugging until I heard the one distinct "click" when I plugged it in - and then I know it would turn on. But now it wont turn on at all and when I can get it to click it is two "click-clicks" and the blinking light returns.

I've called Panasonic to no avail - they said they haven't heard of this problem (ha). They wanted me to get it assessed and I would have to pay for that - I would have to fax them the assessment and then they would assess if they would pay for it. The assessment is 100 and they will not reimburse.
I'm surprised there is no Class Action Suit yet.

I have a bit of electronic experience so I think the best option is to research here more and fix it myself.

Exact same Panasonic model here and mine just went out this evening - ten blinking lights. I really don't feel like jerking around with cables and inputs. I shouldn't have to, my set was purchased 11/25/2008. $1800 for a TV and I don't even get two years out of it. I tried the Panasonic concierge service and got nowhere. Poor customer service and a poor product. I'll never go near another Panasonic again.

Sorry for your situations. All TVs have issues, and once your warranty expires, they don't want to know you.

As pressure increases for less expensive displays, unfortunately, componant and quality control usually suffers, which is why I always recommend an extended warranty. Doesn't really help you now, but hopefully you'll consider one with your next purchase.

Hello Best Buy, Good bye Panny.
All mfg get some bad sets/power supplies, so you just got unlucky. Samsung, Sony, and most other mfg have had this problem to varying degrees.

Exclamation Th-46pz80u a

Hello

I bought my Panasonic TH-46PZ80U A from Best Buy back in Jan 2009.

It has blink problem and refuse to start. This started happening couple days ago.

Once started it blinks twice and then pause then blink twice and then pause and so on.

Just called panasonic tech support and they asked me to hold power button for 10 sec. After leaving the button it now blink 10 times and pause and so on.

But when reseting again it goes back to 2 blinks.

This is well spread issue after reading so many posts about it.

Can anyone help me to find faulty part so I can repair it home.

Thanks in advance

Hey guys, I wanted to jump in here with my issue and repairs. It seems like a majority of the blinking light issues with panny plasmas are connected to a different model then mine but here is the story.

I purchased a panasonic TC-P42U1 from best buy the end of feb, the beginning of March, A couple weeks ago it popped and had 10 blinks, I was able to have best buy retrieve a copy of my receipt and I called the geek squad ad they are qualified to do repairs under Panasonic's warranty. Two boards had gone in my unit, neither of them power related, both had to do with the display, one was the display drive board the other was the H signal substainer board. After the repair the TV has been working perfectly again. My question is, at this point of time, since it took 4 months to fail the first time, how likely is the issue to repeat? Also something else to note, the one board had a bad solder job, and one of the connectors came off in the agent's hand. Like I said though, a majority of this problem seems to be connected to oloder models, so possibly i had a part left over from a bad batch when the TV was manufactured. The one thing I did do was plug the home theater strip into the ups surge side, which has a line conditioner to add extra protection since florida can have dirty power at times.

Any thoughts on the U1 series and how prone problems are? it's a newer series then the one talked about here.

And I'm new to the forum


Thanks.
