Firestick turns off and wont turn back on.

Hi everyone. My firestick (2021 version not 4k) has a weird issue with one of my tv’s. When I turn the tv off at night I leave the firestick on. When I turn the tv on the following day the firestick has turned itself off and is non-responsive. No amount of button pressing will emit a response. I have to get up and flick the power off and on at the socket. This always gets it back up and running again.

The firestick never just turns itself off randomly as a lot of other posters have issues with. It only does it once the tv is off. I suspect it is timing itself out and turning off, but I’m not sure why it then can’t be roused from its slumber.

This is the second firestick that has done this with this TV (Soniq 32 inch about 10 yr old). I have moved one to the lounge where it works fine. I.e I turn the tv off at night and it is all good to go the next night. It is asleep but a button press on the remote wakes it right up.

Any ideas, help or suggestions most welcome.
