Why does my Panasonic TV switch itself off and then on again a few seconds later?
I have a Panasonic TX-L32D25B. It's about 11 years old and basically still works fine. The current software is showing as 2.408. It is not connected to the Internet and never has been. We only use Freeview.
The aerial system is over 30 years old but we do not have any other problems.
We are at Rotherham (Post Code S60 5NP). As far as I know we receive signal from Emley Moor with a horizontal aerial but people nearby receive from Sheffield with a vertical mount so we could be in a dual transmitter zone. (I was once told by an aerial installer that the people down the road have to receive from Sheffield because the hill I live on is in the way of Emley Moor.)

This problem has occurred several times over the last few years. Our local TV repair shop once told me that it was something to do with an off-air component (maybe from the BBC) affecting the software on certain Panasonic models. He advised to disable the off-air update feature through the Setup Menu options. He also said to switch the set off at the mains and after few seconds Press and Hold the Red Power Button on the Handset : switch the set on at the mains while holding the Red Power Button until the picture appeared. I did all this and after a few attempts everything worked ok........until next time which could be months later.

This has happened again recently............
The TV set had been on from about 19:30.
From 20:00 to 21:30 we had been watching a pre-recorded program from our Panasonic DVD recorder (DMR-BW780) connected via an AV/HDMI input.
After 21:30 we found a program on MORE4 (Channel-18) and watched the last half of it via the TV tuner until it finished at 22:00.
We found the same program on MORE4+1 (Channel 86) starting at 22:00 so we set about watching the first half.
After about 10 minutes the TV switched itself off then on again after a few seconds.
This happened a few times so I did the bit with Red Power Button etc but the set still kept failing so we gave up and switched to ITV1 News-at-Ten on Channel-3. But the TV still kept going on and off.
So I switched to the DVD Recorder on the AV/HDMI input : set the DVD to ITV1 on Channel-3 and watched the rest of the news without any problem.
Then watched another program (or recording) via the DVD recorder for another hour without any problem.
The next morning it switched off and on once while tuned to BBC1 on Channel-1.
Dare I say it's been ok since then??!!

Online comments suggest it is some kind of overheating problem in the TV but I'm not convinced about that. As I see it the original suggestion by my local TV shop about some off-air component affecting the TV software (but not the DVD recorder) does make some sense especially when tuned to a non-mainstream channel. Something similar to this has happened in the past with an obscure channel but I can't remember which one.

It may or may not be a relevant aside we used to have a problem with the DVD recorder. If it was tuned to CHANNEL4 (Channel-4) or any of its associates CHANNEL4+1 : MORE4 : 47 : etc but not CHANNEL4_HD - it used to lock up and get stuck on that channel. Eventually I found a work-around to get off it. It seemed to happen after about 21:00 as if CHANNEL4 was transmitting some sort of parental control feature. I haven't noticed it recently so might have been sorted but it did seem to be caused by some off-air signal rather than a problem with the DVD recorder. It didn't affect the TV and it would all work correctly the next day until about 21:00.

Apologies for the lengthy description. I've read some your Q&A and have tried to answer some questions before you need to ask.
My question is...... Are there any off-air signals that could cause this problem? Any ideas to help could be useful. The TV set is proving to be unreliable. Maybe we need to replace it but that could create as many problems as it solves.

Many Thanks

After watching various programs on TV and from DVD recorder for over 3 hours it switched itself off after watching MORE4+1 (Channel 86) for only 10 minutes then worked ok via the DVD recorder for a further hour or more.

Having come across your web-site I would like to ask......

I can expand on this but there doesn't seem to be room here.
Many Thanks
