Xiaomi Mi S flickering and losing sound


Aug 27, 2022
Hi all

I have a mi box S.

So when it starts up the screen flickers and it makes crackling noises.
Then itl lose picture and I have to change hdmi then go back to the original Chanel to get picture back.

And after a few minutes it will flicker and lose sound or just lose sound by itself. And have to raise volume on TV to get sound back.

I have changed hdmi cable and also hdmi ports but still the same thing.
I've tried different settings and still no luck.

Any ideas on what could be wrong?
