Macroblocks using TV, CI+ Module and receiver
I have a strange problem... First off my original setup:
Philips Econova TV
Marantz SR5005 Receiver
UPC Settop box HD
The UPC is connected to the receiver and from the receiver to HDMI 1 on the TV. Watching TV with great sound,
Recently I changed from my settop box to a CI+ module. Here comes the issue... Most channels work fine. But some have no reception, some have no access and some channels, for instance SBS 6 HD, have a lot of macroblocks on screen.
When I switch off my receiver, everything works fine, so I know it's not a UPC problem. For some reason the HDMI ARC input or the Marantz causes disturbance on the digital channel.
How can this be and how can it be fixed? What can I try to fix this? Is the issue in the receiver or in the TV?
