Comcast service reps have been out they tried to program my remotes to work and they can't on any of my 6 Sylvania TVs. They told me to call to have them send out a replacement remote. I can't think 6 could be broken at the same time. Normal Comcast "canned answer" to get you off the phone.
Did you call comcast to activate the new boxes , when we got our self install kits there was a number in the booklet to call . And comcast walked me through setting up the remotes . Also both the TV and DTA box need to be set to the same channel either 3 or 4 . On the back of the DTA there is a selector switch to choose either 3 or 4 .
So I hooked up the new converter boxes and programmed the remotes with the numbers that will turn the tv on/off and adjust the volume but it will not change the channel....it is stuck on CSPAN....please help me!!!! (both remotes only work the power and volume on 2 different TV brands, sharp and sylvania)
