Since we installed our new T.V (Panasonic Plasma 40 inch) it switches itself off for a few seconds then back on again after a couple of seconds, this happens when we switch anything else on in the house, particularly the oven. 
Any ideas what could be causing this at all, this never happened with the old T.V but that was a lot smaller, not sure if this would have anything to do with it.
Any ideas guys?

Id cover the infa red eye on the set, and if the behavious continues then Id return it fir a replacement.
I realise that turning on an oven isnt going to affect the remote receiver, but this is the only variable that I can think of including - when youve doent this the diagnostic procedure is over...

Its a new slimming feature that Panasonic introduced to help people with a weight problem reduce their weight whilst watching TV, it usually happens if you turn on the oven or microwave. Its to stop the population turning into fat couch potatoes.

Sound like the TVs internal power supply is on the fritz and not taking a liking to brief voltage drops, causing the TV to restart.
Just before taking it back...If its on a extension lead/surge protector/adapter. Eliminate that and have it plugged straight into the wall socket. Then try a different kettle lead (nick one off a desktop PC), just to finally rule out a dodgy socket; try a different socket in the house, preferably on a different ring main.
That way you can defintely say its the TV that is duff.
If its a G20 or V20...I'm jealous. Even if its faulty

Oh, just had a thought, if you have Viera Link enabled (via a HDMi lead); another faulty A/V appliance (DVD player for example) may cause it to switch on and off.
Panasonic DVD recoders were notorious for power supply/PCB faults (I know, I have one
- they repaired it FOC though 
).
I suppose a Duff HDMi lead could also interfere with it by messing up the Viera link (CEC) commands, so try disabling it and also turn off any power saving options.

I'll see if I can try a different lead, if I can find one.
Regarding the ring main, if it was dodgy then surely a fuse would pop.

Even a RCD may not trip (as my neighbour found out last month...a loose neutral wire burnt out in the consumer unit and melted, breakers and RCD didn't trip
).Chances its not your electrics, but you never know.

Certainly sounds as though it is sensitive to a voltage drop in the power supply which can happen when switching a power user which needs an initial surge of current when you switch it on.
Could be the TV at fault, or your house power supply.

It's probably the TV that's at fault. For precisely this reason, all electronic equipment legally has to pass a test for immunity to voltage dips and interruptions ("brown-outs"), as part of the same suite of testing to ensure it doesn't interfere with radio communications.
If your TV is resetting, there could well be a fault in the power supply - and depending on the fault, that could lead to premature failure. I'd treat the symptoms you're seeing as a warning to get the set replaced, or at least fixed, while it's still under warranty.
