It is interesting that it works in the bedroom and yet the "tech" blames Keystone.
I'm thinking the system is new and the "tech" doesn't know how to troubleshoot it.

I had a similar issue with my satellite and found, through troubleshooting, that the dyplexer, in the wall plate behind the TV was bad. Moved the one from the bedroom to the living room and all was good.

Loose connections could also be an issue. So far, I have not found any splitters and only one barrel connection in the cable that runs between the Keytv and the living room TV.

Does your on-air antenna work in the living room?
