Looking for some help with what could be going on here. I mounted my Verizon VMS1100 cable box on the wall behind my TV. It's been working fine for almost a week, including last night. Then all of a sudden, I go to use the TV this morning and it doesn't work. The VMS1100 is an IR box, so I guess it needs line of site? That would be fine if it didn't work from the beginning, but it's worked fine for days, and then all of a sudden, doesn't work. Didn't change any settings, power didn't go out, nothing has changed from last night when it worked fine. Any idea what could be going on? Does anyone else have experience with mounting this box behind your TV?
