Proving power circuit is fine?

[tony9i9i9i]

I have a customer saying her TV keeps going off, I've been to visit 3 times, and the circuit has tested fine, with good continuity on the ring, and the voltage is bang on. I removed and few covers and all looked fine, the terminals were correctly tightened.
Not complaining about anything else on the circuit, or other circuits, I think it's the TV but want to prove it.
Is there anything that's not too expensive, that you can plug in to monitor supply presence and voltage over time? Anything similar to monitor the supply to the property. I'm guessing if there is and I had them, I could make use of them.

Has the tv got an energy saving setting? Maybe it’s turning itself off after so many hours?

It could also be a circuit board inside the tv shutting down through to overheating. (Power board?)

A loose connection in the socket, or the plug of the tv?
It might just shut off if there’s a momentary cut in power.

Likely one of the first two if it’s happening around the same time after the tv has been turned on.

You could use a relay that's latched so if the power dropped out, it would stay off.

You could plug the TV into another outlet that's not on that circuit.

If it only the tv that goes off and nothing else then it's the tv thats faulty.The easiest way is to run an extension lead from another socket.If the tv still goes off then it's the tv.If it stays on then its the original socket behind the tv that needs investigating.

A few months ago, the same happened at one of our jobs. The TV switched off, but the lights also flickered. Anyway, the TV is more noticeable.
We tightened everything at the intake and CCU. Turned out to be an issue in the mains and next day the pavement was dug out as the property lost power by 8pm previous evening.
Hopefully it's just the TV. As others said, plug it in somewhere else for 2 weeks, then back to the original socket. Probably your best bet.
