Hallo @ all experts,
I've got a problem with a Sony KV-C2908D TV.
The channels S01 .. 05 (S42 .. S46) and U1 .. U10(S11 .. S20) are working without any problems.
But the channels M1 .. M10 (S01 .. S10) have been remaining black since a few days (also no sound).
Does anyone knows a solution or the reason?

Thank you in advance for your help.
