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??

- my kid can turn the tv off in a way that it wont turn back on. the power light just flashes and it wont come back on. must leave it unplugged for 20 minutes or so then power back on. how can i get it out of this weird standby mode? - GuestMar 21, 2009
- Panasonic TH-42PA20 Plasma keeps shutting off, the red light blinks five times in a cycle, and the only way to get it back is to unplug it for a while and then plug it back in. Very Frustrating! - prtaylor726Mar 16, 2009
- Anyone on the 7 flashing lights? I have the 7 flashing lights and I have the 42PF9431D/37 model TV. One thing that I know is wrong with it is I have a blown white boxed resistor on the main power board. I actually have 2 now because I bypassed the first one just to see if I could get it to work. Having said that I don't think that is the root of the problem. Could it be the SSB. Just trying to figure this out. - ced70Feb 24, 2009
- I have my pc hooked up to my panasonic 42". I got a blinking red light the other day. I unplugged the tv then plugged it back in. works fine soo far. If it was a thermal shutdown I dont think it would have gone back on just after unplugging it. - GuestJan 31, 2009
- my Viera Panasonic Plasma shuts off then I get 12 blinking red lights next to the power button....what does this mean?- Guest

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.

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.

One month old Panasonic TH-50PZ80A plasma TV just switched itself off in the middle of watching a DVD, the red light repeatedly flashed 7 times, stopped, then kept repeating the cycle. Am trying to fix it now using the reboot suggestions. We live in the tropics, so maybe thermals is an issue??

My new 42inch panasonic plasma screen tv (TH-42PC77U) was great for a day. Today, it'll play for approximately 2 hours and turn itself off. I will have to wait approximately 5-10 minutes, and then I hear a clicking noise and I am able to turn the tv back on for another approximate 2 hours. Can anyone tell me what I need to do to fix this problem. The tv is only approximately 4 months old. Thank you

Same problem. Mine is with the 50" Viera 700u. Very frustrating. Its not even 2 months old yet.

At manual power on, the standby light comes on as usual. Then when the power button on the remote is pressed and tv tries to switch on, but after about 5 seconds goes to red light which flashes twice, then pauses, then continues to flash twice and so on. Other than pay the repair guy $198 aud just to look at the tv, when it should be warranty anyway, is there any other solution?

Yes, I have the same problem. My Panasonic Viera PX600 switches itself off and the red light next to the on/off switch flickers and there's a simultaneous clicking sound.
