Screens and audio devices shutting off periodically is a typical sign of clock drift.

It's where a graphics card is outputting 60Hz and the screen is expecting to receive 60Hz, but one of them is slightly off (60.0001Hz).

At some point the sending and receiving get too far misaligned, some error condition is triggered, and the whole thing restarts.

It's a design flaw really - you should never recreate someone else's clock signal.

There are some times it's impossible to avoid - for example a picture in picture mode has to synchronise with two other people's clock signals for each of the incoming images.

In your case, temperature will affect the speed of the oscillator making it happen more frequently unless you have the ideal temperature.
