Red light blinking-Panasonic TH-42PD50U

Need urgent help as was planning a Super Bowl party and my TV went dead.

I accidentally hit the power button on/off very quickly. Screen went dead and red light on lower left blinks 10 tims w/3 second pause. This happened a week ago and apparently corrected itself, as this must be some safety device for the TV. This happened again last night and nothing I do gets the TV back on. I have unplugged power, waited, etc. Left if off last night and still have the problem today.

I went online and found a tech manual for another Panasonic model (different from mine) and is showed flashing red lights as diagnostic tools, but it only went up to 6 blinks (mine does 10).

Any suggestions to help me get back operational for the Super Bowl would be appreciated.

Hi There,I read another site

Hi There,

I read another site that the guys young daughter did the same thing and it could have blown a fuse and or a small cheap transistor or resistor on the main board...Sorry, but you may need repair service man...Doing it yourself could be dangerous and cause more damage even to yourself!

AWAHOO, My 26 month old

My 26 month old Panasonic CT-32HC43G quit working. I unplugged the power to reset the factory settings. When I plugged it in and hit the power button there was some quick clicking (like a solenoid that was hunting) and it stopped. Now the power indicator light flashes 6 times and stops and repeats. Can you tell me where you found the tech manual online? I just need to know what the 6 blinks is telling me. Thanks, Chris

Sorry. I tried to locate

Sorry. I tried to locate where I found this but could not. I thought it was on the Panasonic web site.

Thanks for the effort. It is

Thanks for the effort. It is going to aggravate me to have to spend 200.00 to fix this TV. I know it is a 35.00 part.

I hope it's only $35.00. My

I hope it's only $35.00. My original 10 blinking lights meant a $72.00 circuit board. When that was replaced, there was a voltage drop, and then the second part was $372.00 and on backorder for 6-8 weeks. How would you like to have a $2000+ new plasma TV to go bad after 46 days, then have to wait that long. Panasonic and Best Buy warranty suck!

OOOOUCH. I bought this Panny

OOOOUCH. I bought this Panny at WalMart. If it were not 26 months hold I would have brought it back. Maybe i should just scrap it.

I just had the same issue on

I just had the same issue on a 42 TH-C42FD18. I called Panasonic, returned the TV and had the same problem again. 10 blinks and no tv. Called again and had them do a little more investigation. They are telling me that its the cable box. Basically some cable boxes and computers maintain a 3v state upon shutdown and causes the Panasonic to think there is an issue. Works fine on my Sony though. Anyway, they said if you have a

I recently had my Panasonic

I recently had my Panasonic TC-P50G15 blow a board. My wife was watching and the screen "flickered green" and then turned off. I had the tv plugged directly into the wall (I know, I know...) and it was about 40 days old. I'm not sure if it was a power surge (some construction in my neighborhood) or just a bad board. I bought it online, so returning it would have cost a fortune, so I just worked with Panasonic. They sent a regional technician out to assess the damage (he concludes that, yes, it is broken, and counted the number of power-light blinks). They called panasonic to see which part corresponds to the number of blinks, and ordered the parts. A different guy came back about a week later to install it. Overall it was really frustrating, but the service (from both panasonic and Electronics Service Center in the DC Metro area) was really good. You just have to be patient. I guess thats the price you have to pay when you dont buy from a big-box store. I now have all of my stuff running through a line conditioner/voltage regulator (same thing). Look on amazon or newegg - I found the APC LE1200 for about $50, which is cheaper than a "good" surge protector, and does a much better job

I own a 50 inch Panasonic that I bought in 2007. This TV is a victim of a failed DG board and 11 red blinking lights. Panasonic has had widespread issues before, specifically with their light bulbs in the early 2000's. Below is a link to this class action settlement by Panasonic; it can be done!

Short story is I think we have enough parties to file, but I do not know for sure. Is anyone familiar with the number of people and $ amounts required to file a class action? I live in the southeast and have friends that are attorneys. I am considering contacting them to pursue this matter further.

However, I would like to compile information prior to contacting them. I have set up an email "panasonicclassaction at gmail (dot) com. Not sure exactly what information I need so I will start broad.

Please email me your name and email address, model number, date of purchase, date failed, the issue if diagnosed and number of red blinking lights, the repair bill if estimated (if you don’t have these prior two do some internet searching and I bet you can get a good estimate) and any other pertinent information you think I may need. Also, make the subject line “Panasonic TV failure” to make it easier to sort through.

I am going to compile all this information in an excel spreadsheet and I will provide it when I contact an attorney. I have seen lots of complaints about this problem across the internet, but I am not sure how many posts are overlapping. This will be a good way to determine an exact number of failures and the associated costs. I will start an email list and keep everyone updated with any new information. Please post this information as many places as you can (you can copy and paste this verbatim if you like). We need to disseminate this information so that we can get an accurate estimation of people affected by this problem. Thanks for your help and letÂ’s not rest on this issue!

I've got a 46pz80u, purchased

I've got a 46pz80u, purchased May 2009. TV is great, but we noticed that if you turn the TV off, then back on rapidly before hearing the solenoid-ish click. I had it serviced via warranty, they replaced two boards on the unit and it still behaves the same way.

The TV works fine as long as you wait for the click after turning it off --- I'm just concerned about issues after the warranty expires. I will probably call Panasonic again and get it serviced + replaced if necessary. Maybe this time I will suggest replacing the power supply.

I have a Panasonic TH-42PZ80U

I have a Panasonic TH-42PZ80U plasma HD TV. Its been only 1 year & 9 months since I bought it from Sears. I am having the same problem. Once I switch off the TV and restart it will not and the red light on the left bottom near the start switch will start to blink. I would unplug and try to restart, but it not start. I would do it again and sometimes it may start.
I don't know what to do or whom to contact. Please advice.

I had this happen this

I had this happen this morning; I didnÂ’t count the lights as I had just woke up and wanted to turn the news on. When I saw the red light trying to tell me something i went to the TV held the power button until I heard the relay click again released the button counted to 10 SLOWLY and pressed the power button and boom picture and sound. Just an FWI the 10 second power/reset button is on most modern devices for those who donÂ’t know...

I have had the same issue.

I have had the same issue. Bad power board on a Panasonic plasma just over a year old. (and just out of warranty.) While the technical issues a clearly a problem, my concern is poor customer service. I encourage you to come add your thoughts to mine on the Panasonic fan page on facebook and maybe we can get a response from Panasonic.

After reading djb's email I

After reading djb's email I've decided to call into Panasonic for another service for my 10 blinking lights after turning TV off then back on. The TV is out of warranty in a week, concerned about the power board going out post-warranty.

Panasonic customer service was good about quickly scheduling a service call, will report back when the unit is serviced this Thursday AM.

Hey JesseBrew, let me know

Hey JesseBrew, let me know how it goes. I literally just had the 10 blinks happen to my tv tonight when I tried to turn it back on. Let me know what they say 10 blinks means and what the repair costs for out of warranty. Mines a TH-46PZ85U

No problem, service

No problem, service appointment is moved to Friday morning. I spoke with the service folks and they mentioned ordering a power board and another board (maybe a C board). These were the same boards they replaced before, so either one of the replacement parts was defective or there's something else going on.

Either way will report back w/ repair estimates, mine is a TH-46PZ80U.

Just came across this tonight, scary stuff -

Really hope Panasonic decides to stand behind their products.

Update on my TH-46PZ80U:

Update on my TH-46PZ80U: Tech came over Friday and replaced the main board + power board (~$400 in parts but this was covered by my warranty). After replacing the boards the TV wouldn't start, only displaying 10 blinks.

The tech worked with Panasonic support and determined the replacement power board was faulty, so he put back the power board and left the replacement main board installed. The TV seems to be working now, even turning it on / off but I HAVE to wait about a minute to cycle power.

I'm concerned about the longevity of the TV, happy to have a 2yr warranty through CostCo.

Good luck out there folks. =/

Just experienced "10 blinking

Just experienced "10 blinking red power light" problem. Panasonic plasma TH-42PZ700U. Have owned it for 2 years and 2 months, it's outside of warranty and I didn't get an extended warranty. TV was working fine on Friday night, and then was stuck on 10 blinks on Saturday morning.

Called Panasonic plasma concierge, and they said the fix would be covered by the warranty, despite its expiration. They arranged for a local shop to send two repairmen the following Thursday, and the guys did a great job - replaced the entire SC board in 12 minutes, then made a software update using a memory stick at the port on the front of the TV. They said that they see this problem fairly often. With the new board and firmware update, they said the problem shouldn't happen again.

I ordered the complete service manual, it is very helpful, well worth the twenty five dollars.

My Panasonic TH50pz80u died

My Panasonic TH50pz80u died after 13 months. It will cost 1,000 to repair. Boards A and D failed. A class law suit is a good idea. Connect to this blog:

I had the same problem...

I had the same problem... turned out that the bulb was bad. Easy to check... just remove front panel, remove bulb cover screw on the left by the caution label, remove bulb housing screw on the right, then slide it out and inspect the bulb.

Hope this helps...

By the way.. found replacement at for 129.99. Panasonic wanted 250.00

Good luck to all.

Ok, 50" panasonic plasma

Ok, 50" panasonic plasma start experience the 10 blinking lights of death. Panasonic gave name of local shop. TV is 15 months old. Replaced the 'A' board. Took it home. Did not work, 10 flashing lights, dragged back, replaced 'A' board again, Did not work. Told me I wasn't waiting a full 60 seconds after turning it off before turning it on. HUH? So this time after talking to Panasonic Concierge, same shop picked it up and now they are waiting for a 'P' board.

Bottom line I probably should have taken the $500 in repairs and used towards a Vizion. It's going to to be another 2 weeks before I know if the 'P' board fixed the issue.

Winston. Can you please

Winston. Can you please contact me about how they got your TV fixed. Did you find out any info on what it was being covered by. My TV is doing the 10 flashes and I just got told to pay for an evaluation so I know how much it will cost to fix but that I am out of luck.
