DBox2 with signal-problems (HW-Problem?)

[Onefeet]

Hi guys,

i have searched a lot in the internet and this forum here, but nobody has the same problem like me.

Hopefully i can find someone here, who can tell me, what ist wrong or how i can find out what the real problem is (SW or HW).

Situation:
I have two DBox2 and both are having the same Image (zebradem 3.52), which are both working with cccam. The first box is working fine, but the second one is losing the video-signal from time to time. So the screen is going to be black and after one or 2 minutes the picture is coming back.
I turn on the box. After 60-80 minutes the error comes up the first time. Then every 5-15 minutes.

I already have reflashed the box, but that didn't solve the problem.

Typing dmesg in the command line shows this:
