[HD] Channels working upstairs, not downstairs
I've been having a problem lately, mainly with the SD weather channel (101) and the HD History 2 channel. Downstairs neither channel comes in, or comes in with major pauses and pixelation. Upstairs, however, both are fine. The boxes are identical Dcx3400's. Any ideas on what it is before I call?
Most likely a signal issue. (faulty splitter, house wiring) And no matter how many times they hit the box, you will need a service call. Sometimes the channels may start working after a hit, but almost all the time they will start tiling again soon.
