Lower channels with no signal
I have two TiVo HD models. I'll call them Living Room (LR) and Master Bedroom (MBR). Both have Charter cablecards in them. In my area (North Texas), Charter went all-digital (June 11). The cable coax comes into the attic, hits a splitter, and then two separate lines go to the living room to feed LR and the bedroom to plug into MBR.
So same models of TiVo and same signal coming in.
The problem is that the MBR unit is not getting a signal for the lower channels: 2-13. It was previously getting those signals, but stopped 2-4 days ago. The LR unit has those channels with a strong signal.
I am at a loss for where to begin to figure out why MBR is not receiving those lower channels. Does anyone have a suggestion?
