Odd issue with TV turning OFF when another device is turned ON.

[static zap]

Does this happen all the time , or only with the Light on in the TV room ?
(Some lamp flicker can upset IR systems)
(a different location = a different lamp !)

(also consider having socket changed if its switch has a poor action)

Does the television actually switch off or do you just loose the picture and sound? It could be a marginal signal and electrical interference from other devices being switched on is causing the problem.

Now you have to work out if it is the outlet or the television ?
Leave the tv where it is and plug it into an extention lead,
Then run power from another circuit see what happens.
And plug a lamp into the outlet, watch it and see if it blips out.

now that everyone’s confused, I think the OP answered his own question with faulty power supply/ power board in the tv itself.
Not very practical maybe, but can you test
1. A different tv in that location, plugged into everything as this tv is.
2. This tv plugged in elsewhere in the house and see if fault continues.

That is a great idea. Kicking myself for not thinking of it but glad you did. I will swap my two flat screens over for a day or two, see if I can repeat the fault.

Oh how I wish is did.....lol

No, it is not only the light upstairs it can be almost anything in the house. Printer is on the Ring Main, upstairs, connected via WiFi and starting that printing can sometimes cause it. Not always.

New Socket, New Plug on TV, cut off the moulded one.

Don't get people started on cutting moulded plugs off

That is exactly what happens, yes a much better explanation of the events. Loose Picture, Sound, then it comes back.

Done, done and done. Lamp fine, TV goes off. lol

My bad. I moved it there. Moved to lighting forum lol

You are forgiven.....lol

You are forgiven.....lol

It still might not be a lighting problem in the end lol so award for most moved thread if we move it again once finding out the actual issue.

This is a very important point. It implies that the problem is not electrical as such, because the TV power is not being affected, only the signal. As per Jim_e_Jib if the signal is just barely strong enough or of marginal quality, ordinary radio-requency interference from any source can disrupt the reception. Could be something amiss with the aerial / downlead / booster / splitter / TV itself.

Check the installation menu for signal strength / quality indicators and if they are available, see how your signal measures up, before deciding on a course of action.

This is quite a common symptom in installed AV systems where signals are being sent through cables right near their maximum permissible lengths. By the time the signal reaches the target device it is heavily attenuated and almost lost in the noise. Although it might work most of the time, a crackle or pop from anything nearby can push the error rate over the limit and kill the picture for a moment. E.g. We had one installation where closing the electric blinds would blank the screen, and another where the sound would go off when the coffee machine heating element was up to temperature. No electrical fault in either case but inadequate signal transmission due to poor choices of cable types and lengths.

Aerial? NO
Downlead? NO
Booster? NO
Splitter? NO
TV? YES

Alright, I will add more details. This happens if the Source feeding the TV is:
Nvidea Shield. Via HDMI
Virgin TiVo Box. Via HDMI
Blu Ray Player. Via HDMI
File on a USB Stick in one of the TV's ports.
Motorised Satellite System, VIA Component Cables 3 Video and Optical for Audio.

No terrestrial TV at all connected now or ever.
