Question about Flat Panel Televisions
Frustrating symptoms on brand new Panasonic Viera 42" plasma! tv just turns itself off sometimes without warning or if changing to certain channels. leaves red light flashing for a while then red light goes away permanently so no longer in normal standby mode. any attempts with remote gives flashing green light on tv. manual power off and on restarts tv but auto off again. found during manual power on, keep changing channel on remote till stable picture appears. then use remote to shut down tv - solid red light indicates normal standby mode. then use remote to turn on again, and it works... till next time it happens. but what is technical fault??
Hi to all, My 42" Panasonic plasma have the same problem. It turned itself off and now red light flashes 7 times, than after short pause 7 times again. And so on. Any ideas what is wrong??

Our 42 inch panasonic plasma turned itself off and it too has 7 flashes and then a pause and it will not turn on at all. Not by the button or the remote. No sound or picture and I cannot get the flashing red lights to stop unless we unplug it...We reset the remote and the cable box but nothing... Please help .. we lack funds to fix this or we would pay someone here.

I have a Panasonic Viera TH-50PV60A and after turning on will switch off in stand bye mode with the red light flashing for 11 times repeatably. Tried unplugging the TV for 30 minutes which left me with the same undesirable result... any thoughts?

Turn TV on and turn off using remote before it has automatically shut down. red light should now be stable. turn back on using the remote and picture should be stable

Ok guys... The 12 light flash is an error code that means the H board needs to be replaced. This may, or may not be the final solution, but its a start. The problem with mine was that there was a wire that had been pinched on the right side. Its in the front by the speaker. You will have to remove the front part of the TV to get to it. If a tech comes and looks at your TV's . Give him all these options. Also have him replace the power source just in case. Mine is 100% better. Hope this helps.

Hi there, have the same kind of problem twice so far after was bought for me as x-mas present (although my viera isnt plasma, its an LCD TX-32LMD70A)..
I Pulled out the mains plug for about 10-20 seconds and then plugged back in (power button at top was pushed in, in the on position, so when the power was on, the tv just goes straight on). It then worked.
i would however like to know why this happens ( i really hope this isnt a hardware problem, as like many others... its only months old!!)
hope this helps

Hi Guys, looks like, it is a thermal shutdown issue. Try the following: Keep a fan and direct the air towards the bottom vent holes. Switch on the TV. Keep it on continuously for more than 2 hours and see if the TV shuts off again. If not, then it confirms Thermal shutdown. Check if you have kep any papers, cloth etc very close to TV. Keep the TV ventilated. Let there be air circulation.
Do this and post your experience.

Panasonic TH-42PA20 with 7 led blinks is a safety feature to shutdown the unit before more parts are damaged.
Unfortunately the circuit that controls that fails too... Replace the SC board and you'll be alright.(board on the left (back view)
For the techs.. check the comparator circuit that drives the sos1 signal.

After reading everyones posts I belief the overall solution would be to boycott buying Panasonic products all together. It seems as though I was on the fortunate side. I bought mine in July of 2008 so I almost got four years out of it. I remember regular tv's lasting way longer. My dad still has an RCA tv which is 28 years old never needed any repairs. I swear things built in America are meant to fall apart.

Definitely an indication of an overheat problem. My 5 yr old 57" Viera experienced this for the first time last night. Holding the power swith stopped the flashing (11x) light, But powering back up the set would come on then go off after a few seconds. Unplugging didn't help either. Looking at the back of the set, I noticed some air vents that were pretty well clogged with dust. I brought in my portable air tank and thoroughly blew out all of the vents in the back of the set. Turned it back on and have not had the problem since. Can't blame Panasonic at all. Heat and dust is the enemy of all electronics.

If eleven flashes, either take the back off & clean the fans and hoover up the dust or use a torch & look through the back grills where the fans are, see if both spin when turning on. Then use a hoover with a brush head and get as much dust off the bad fan & make sure it spins when moved with the brush. Then turn it on & it should work. One of my fans just stopped spinning because of the amount of dust on it. I cleaned it as much as possible using the second method & "hey presto" it started spinning & works again. If/when it happens again i'll take the back off & give both fans a proper clean. Hope this helps

Had the same problem just over one year in with my VIERA 42" plasma. Estimate for repair $650.00. Price of a brand new Samsung 42" plasma $629.00. What do you think I did. Poo on Panasonic. I will not buy from them anymore.

Hi everyone and Happy Holidays, I purchased a Panasonic Viera plasma tv model TC-P42ST36 a few weeks ago, and about a week later after my purchase the tv shut off automatically. I turned the tv on and didn't noticed anything unusual, and a few days later I was watching a movie and a message showed up in the screen. It said the tv would shut down in a minute or two. I pressed the ok button in the remote control and message went away and the tv didn't shut down. A few days later I took a nap and the tv shut down, so when I woke up I noticed the tv was off. I started wondering about the issue, I went to forum and and ask my roommate if he had noticed any similar issue with his LCD tv which is a couple years old. That's when I found out that some if not all recent models tvs are eco friendly and they shut off automatically after certain time, usually 2 or 3 hrs if you don't press any button. I guess the tv assumes you fell to sleep or forgot to shut it off. Also, some tvs do the same thing when they are connected to DirectTV box and maybe to other servicers' boxes to avoid tv eating out faster and to save energy. I would check in the setting menu the eco/energy saving mode, and make sure that either is on (in my tv it says it shut off automatically after 3 hrs with no remote control action), or if it is off you may try something else. I hope this helps, particularly for those that have a recent tv model. Good luck and Happy Holidays.

To all those who want to boycott Panasonic for crappy products: I'm very sorry you are having problems with your Tvs but all my tvs are Panasonic and I've had them for years without any issues. The sad truth of the matter is that you are a very small percentage of Panasonic
TV consumers. Trust me, if their products were as widely faulty or all "meant to fail" as some people on this blog have alleged, there would definitely be a boycott or widespread recall of some sort.

My Panasonic tx-55as640 has started to turn itself off its only 14 months old and only used for up to 4 hrs a day. PC WORLD are not interested. I will try Panasonic directly tomorrow. This is obviously a design fault. My old TV lasted over 10 years.

I just bought a panasonic 42" led tv. in half an hour after the installation it keep restarting on and off about 3-4 times per hour. it less than 40 minutes from installation. I call the technician that install it, he just ask me to do reset to factory setting twice.. I will ask them refund my money. I dont think that warranty will solve this, why do panasonic wasting money for replace broken part when they can solve it before their product come out from factory.
