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

[Nimiq1]

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.

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

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.

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.

This may be a bit of a red herring but did the television come with a ferrite bead for it's power cable? If so, have you used it?

Few months ago I was working in a house and the tenant had this problem. The kitchen had two identical fluorescents separately switched and one of them, always the same one ditched the signal to the tv when switched on.

A systematic approach will be needed to find if
a) TV is over sensitive (try another)
b) interconnected equipment is funneling in interference.
c) TV temporarily confused starts selecting another source
if more than 1 present!
---
Start with bare minimum HDMI's connected
Just ONE = Blue ray player , no amplifiers or sound systems...
gradually re-building system with more parts.
See if interference stays away until a certain component is added!
(Any figure of 8 mains cables)
(Also leave satellite system -disconected at some point)

I like your thinking but sadly no. Have a couple lying around though, no harm in wrapping the cable round them is there..?

Did that and the TV that was placed there had Zero issues. Odd TV, still did it but it was now being used as a Computer Monitor

b) interconnected equipment is funneling in interference.

Possible yes.

c) TV temporarily confused starts selecting another source if more than 1 present!

Not as confused as me.....

Start with bare minimum HDMI's connected Just ONE = Blue ray player , no amplifiers or sound systems...gradually re-building system with more parts. See if interference stays away until a certain component is added!

Think we have done that but I will try again, with just the TiVo box connected. I will physically unplug all other devices, except TV and Router. Using TiVo because it is so intermittent I would get killed if we are limited to "The Fringe" again.....lol

(Any figure of 8 mains cables)

Great question, to which the answer is ..... No idea.....

(Also leave satellite system -disconected at some point)

Done.

Have you tried to unplug everything. All HDMI's the lot. And run your TV on it's own, even in settings menu, and see if it does it then. If it has power the whole time and it's just Vision that goes when you flick the switch. Try running it with nothing in, and no power to all the devices, and then add them one by one?

 

[Nimiq1]

I am not sure it will stay switched on if it is just Settings Menu, think it times out and then goes to sleep if no signal within 5 mins...But, I will dig around in the Menu tomorrow.

 

[Dan]

Just be quick. Lol

Unplug everything first, whack TV on its own on, and see if you can get it flicker or whatever it's doing.

Today is a Video via USB only day for the TV, nothing else connected, power is via extension cable to a separate socket alongside the Consumer Unit.

We shall see...

Of course, since I started this thread it has behaved perfectly, maybe it just wanted a bit of internet attention.....lol

 

[Nimiq1]

Just wanted to come back agin to thank everyone for their suggestions. Having gone through the entire house and checked tightened every screw I a happy to report that I think I found the offending thing. Well, in the Consumer unit the Neutral feed from the meter was loose, it took way more turns than it should have, didn't see any signs of arcing, not sure if I would or not but anyway there was none.

Found 3 or 4 really grotty looking connections i an upstairs room and even a live cable just hanging in the wall cavity space. Not terminated or anything, looked like it used to feed an Expelaire which had been removed and the wires just left hanging...Hmmm, not clever.

So, over 2 week now and the TV is behaving.

Thanks

Nice one. Thanks for letting us know. You have the added bonus now that your installation is a little bit safer too.
