Some say that's the norm just like CRT & some don't. I know on my Sammy 5084 plasma such bright flash didn't occur.
lots of failure was reported on that model I guess I got lucky.

A lookse what many owners of that display were dealing with,

Yeah A bright flash on a plasma doesn't seem normal, my U1 just shuts down when hitting the power switch. The screen just goes black and a single click, power led goes out. same with power on, a single click the screen turns on, the tv boots.

ya well I'm going to stop by BB tomorrow take look at floor model see if flash occurs.
If it doesn't I'm going to get with manger see if I can swap out.
I highly doubt he will allow seeing first one was purchased on November 29 which I returned due to dead pixel on Dec 7th for this one.
I think customer only has 30 days from original purchase date the Dec 7th exchange doesn't fit into that formula.

That's correct, I had issues with returning stuff to bb a while back I mainly just didn't understand the return policy fully, and That was back when I couldn't find a decent blu-ray player from 2010 that I was fully satisfied with. So i bought and returned too many units on the same receipt without realizing I had violated policy. If they won't let you return the unit, They will offer to have the geek squad come out and look at your TV free of charge, and then if it's still under panasonic's warranty they will repair it if need be free of charge. At least you won't have to deal with panasonic directly in this case. I didn't and I'm fully satisfied with the outcome. In reality, plasma is a solid technology. If you look at flat panel TVS in the broad spectrum, you'll find just about the same amount of issues for all types of flat panel tvs and manufactures. Plasma has just gotten a bad reputation from it's initial problems of burn in, plasma half life etc. With the latest generations though, these have been long since taken care of. As far as flat panel tvs, they all have known power issues, parts have gotten cheaper and quality control isn't what it used to be. Hopefully you'll have a good visit to BB tomorrow and your apprehension is just a lack of understanding of plasma technology. Different panels and sets may behave differently as well, after all plasma is phosphor based like a CRT, so some panels may turn on and off like a CRT. I just don't have the experience with flat panels that I do with CRTs, so i'm still learning about the technology myself. (studios prefer CRTs for reproduction over flat panels.)

When it comes down to it, if Panasonic doesn't figure out what is causing these problems they are going to lose a lot of money in repairs and refunds. But not only that, customers also.

It seems to me that there are just a lot of problems with plasmas still. Whether it be buzzing, floating blacks, etc. Oh and I started to notice a lot of floating blacks just before my TV went dead. It never did it when I first got the TV. It might be a sign of things to come for the G25 series.
Haven't you ever had a car that had an issue? Did you condemn that mfg or even better did you blame ALL cars?

Panasonic has the highest reliability ratings and you happen to get unlucky to have bought one that had issues. Panasonic sells more plasmas than anyone else and they are the number 1 recommended brand at most HDTV forums for a reason. No one wants to be the unlucky one and unfortunately you picked the short straw this time around.

Other than the possibility of burn in if you abuse a plasma or use it other than as intended, they are as reliable as LCD, and actually less likely to get a stuck/dead pixel in general.

This thread has been the catch all for the flashing power light issue and gets a top level hit on Google so it catches likely anyone who ever owned a Panasonic plasma and had this issue. I remember reading somewhere that they sell over 1 million plasmas per year and if you look at the number of unique posters here it is a low number for the most popular plasmas brand.

If you are looking for a display tech that is as mature as CRT then you have some waiting to go until either tech gets to that level of simplicity/reliability if ever. CRTs were simple and only had to handle ONE resolution (being SD 480i), so just that alone would make it less complicated and less likely to have strain on components like HDTVs have. I remember reading about a lot of CRT based HDTVs having short lifespans and that was with CRT tech being around for over 50 years. So that shows the additional strain of the current HDTV displays having to handle repeated resolution changes on the fly as fast as you can change the channel with the remote.

LCD has their problems as well BTW. LCDs have motion issues, backlight bleeding, poorer viewing angles, capacitors swelling and causing the same blinking light issue, pixels stuck or dead, etc etc.

IMO, ALL mfg should be offering longer warranties on these HDTVs considering the prices being paid for them, but that is another issue for another thread.

But do not look at one issue and think it is a flawed tech. When I bought my first HDTV is was a LG DLP, and I went through 5 of them and then 1 Samsung DLP, and they all had issues and I got very frustrated. I ended up with a RCA DLP and it has been fantastic and is still going strong 6 years later.

Bestbuy visit went well some what.
The bad news,
Took a look at floor model it was hard to tell if white flash was present due to store lights shinning bright.

The good is that my purchase falls in their extended return policy date January 31st....a holiday thing of theirs.
My original display was purchased on November 29th which was taken back for new on on Dec 7th.
That Dec 7th exchange gives me up to January 31st to return if issues arise due to extended return that shows on receipt so good to go there props to Bestbuy.
Reps holding one for me yet I sure is heck don't want to return one I have if its G20 norm power off so its time to do some research.
hmm I think I will start fresh thread on topic.

UPDATE:
I swapped out for new this one doesn't light up when powered off it goes dark as should so my exchange gamble payed off.
Now to my G20 unlucky history,
1st G20 had 3 green flickering pixels.
2nd display flashed when powering off.
3rd - The current has no issues that I can tell everything looks good thus far , fingers crossed.
Now back to what plasma TV owners love , The break-in session lol

Been lurking around this thread for a few days now and think my Panasonic Viera TC-P50C1 is going to be dying soon after reading a lot of this thread.

Purchased this TV in February of 2010 from Walmartcom and moved rooms around June/July. Never got around to hooking up my TV so it's just been collecting dust up until December ish.

Started playing my video game consoles again very recently and all was well until about a week ago when my TV just turned off and started turning on and off repeatedly. Said, "god damn it" to myself thinking it was dead, went to sleep for the day and tried playing again the very next day with no problems whatsoever. Fast forward to yesterday and same thing happened. Unplugged the TV, unhooked all my consoles, rehooked everything and it worked fine for about 2 hours. Stopped playing again to go to sleep, come back from work today and here I am playing a little Xbox and it did it again.

Shot Panasonic an e-mail and they said replug it into a different power source and if that doesn't work call them up. So far it's working, however, I'm coming up fast on the one year mark so I'm not sure I should be waiting around to see how long this works.

Should I just call them up and say their fix didn't work? Even if I can't recreate the scenario when the Panasonic dude comes over? Don't even understand if this is working because it's a fix or dumbluck. Just want to enjoy my games before school starts next week

Call them and have them come out BEFORE the 1 year mark to get the issue on record for sure with a piece of paper in hand that they came out within the 1 year warranty.

Default Additional Problem than just the 10 blinking LOD

Ok so I'm not a tech savvy person so I don't know the exact name of my Panasonic TV but I do know it has the 10 blinking Lights. So I read most of this thread and tried Tarrant1701's solution back from when this thread was created in '08. It worked. Moving the HDMI cord to the front 3rd port fixed it. Here is the bad news. The bad news is if I turn my TV off and try to turn it back on. The 10 Lights of Death come back (And this is on the 3rd HDMI port). So what I have done is I unplugged the TV, unplugged the HDMI cable and put it back into port 1 or 2 doesn't seem to matter. I plug the TV back in and the 10 blinking lights resume. I then unplug both and put the HDMI cable back into the 3rd port and plug the TV back in. I press the power button on my remote and BAM! It works again. My question is how is this possible. That even while in the 3rd port I still can't turn my TV on and off. Very frustrating. I know I'm going to have to call Panasonic but I just wanted to see what ya'll thought about it. Thanks for your help.

Default sudden death for 2.5 yr old Panasonic w/ NO red blinking lights

Has anyone ever heard of early death to a Panasonic with no blinking lights remaining? I bought my TH-42PX75U on 7/7/07 and had it die on me on 1/8/11, nearly exactly 3.5 yrs after purchase. Unlike many others, I have no red blinking lights at all. Any suggestions? I was referred to a local authorized repair shop, and may drop it off, but if it's clear which board is the problem (if only one is the problem) and it's easy to unscrew and replace, it can someone generally handy but without experience working on boards replace the board? I'm very reluctant to open the back up and tinker, and I'm upset with Panasonic until and unless they agree to underwrite some or all the repair costs.

Thanks in advance.

Your display might be one of the models with a known bad part that could get parts replaced for free.

I would call Panasonic.

Good luck!
Wow. You called it. Once I gave them model & serial number it was like they couldn't GET a guy out here fast enough. Now, four days post-repair, wintered in and watching a lot of TV...so far so good! Thanks again to all who've posted here (and the guy who replied personally as well.)

Glad they took care of it and so fast for you. Not bad having Panasonic pay for repairs on a 37 month old TV for free huh?

Hi,
My 2 and half year old Panasonic Viera TH-46PZ85U is giving me the 10 blinking red lights. I have disconnected any HDMI cables connected to my TV yet no solution . It now gives me the 10 blinking lights sporadically. I have to disconnect it from the power source for a while to get it back on.
I have tried calling customer service to get to the tech support but gave up every time after being on hold for 30 minutes.

Is there a good time when I should call? Can I expect panasonic to repair my TV free of cost because it is now out of warranty?

Thanks in advance.
