TV keeps turning off

[hcw522]

I have a Sony Bravia 65XD8599

The last couple of days it keeps switching itself off then won't turn back on with the remote, having to switch it off at the mains and wait a while before it'll come back on - but then it just switches itself off again.

No sleeper timers or anything like that. Have unplugged everything that was plugged into it but that hasn't helped. Have done a reset but that's not helped, either. Power cable seems fine, nothing looks loose or out of place. 

The longer I leave it unplugged at the mains, the longer it stays on, but so far that tends to be about 30 mins before it switches off again. 

Have run internal diagnostics but the TV hasn't picked up on anything wrong. Not sure what to do at this point.

Any advice appreciated, thank you

Are you able and brave enough to take the back cover off to see if it isn't clogged up with dust which may be causing it to overheat and cut out.

Are there any flashing LEDs on the front of the TV whilst operating or starting up?

Does this TV have a separate power supply, you could try trawling the internet for a replacement

to see if that is the problem. That is if you want to spend money on it.

As  it is now quite an old TV it possible is coming to the end and a repair may not be financially worth it.

Fancy a new TV??

No flashing lights, seemed to work perfectly normally when it was on

Tested it today and now it won't come on at all, do you know what kind of costs it would be to have a technician take a look?

No idea how much it would be to have someone come out and have a look at it.

But keep in mind if parts need to be replaced plus labour the cost could escalate rapidly.

Usually if some component or other has failed or is failing the TV will display a series of blinking LEDs

of varying numbers of blinks to identify which component is problematic.

If you do call out a TV engineer make sure that they are familiar with Sony and in particular

your model, as a diagnostic they will probably plug in a laptop and download the problem information

from there. From there they will be able to give you an idea of parts availability, repair time frame

and an estimated cost including labour, also ask if you get a warranty with the repair and how long it is.

If the costs don't make sense for such an old TV then think about a new one, yummy.
