Today I repaired a SAT Receiver, it was easy because I found immediately the culprit: the VDD cap, on VIPer50S supply voltage, was completely out of spec, it was 1.22uF 565ohm instead of 47uF.
I think it is normal that after some years it failed because Rubycon YK are not low ESR for high frequencies.
I replaced it with 47uF 25V YXF.
Here some pics.
