Problems with Xiaomi Box MDZ-16-AB. The screen is flickering

Hey.
On three different TVs with different HDMI cables and different power supplies on the same box, the same problem - the screen flickers. I don't think that this is a software problem. How do you think this can be fixed?

What Happens if you move HDMI very slight(wiggle) while plugged in can you reproduce that fault or make it happen. ?
Try Lower screen Resolution or Higher ?
or damage to hdmi port.

I tried. HDMI plug works fine. The display shows the image or not, without distortion. I think that some element on the PCB is poorly soldered, because when the box is working long and heated, then artifacts of the image appear less often.

If you have warranty i suggest maybe do it..
If not you can try and solder, But may end up worse...

Hard one to call...
