You most likly need a HD box for that TV. TV tuners are for OTA (Other the Air) channels. If your tv has a Cablecard slot you can get one of those (rent from the cable company) or a HD box like what you have in the living room.
Anyway for more help we would need to know how the TV is hooked-up, cable/wire wise, like to me it sounds like your running the coax from the wall directly to the tv (?).
I recently bought a Samsung PN42A450 for my bedroom and have been unable to get any basic cable (ABC,CBS etc..) HD channels through the tuner. I have a HD box on my TV in the living room that works fine so I am a little unsure why it isn't working. One suspicion is that my cable connection in the bedroom isn't that great and is a slight bit fuzzy on some channels but I don't know if that would prevent it from getting HD or not.
I put the Sammy through the normal setup routines where it detects channels and no digital channels have come up so can anyone provide advice?
Thanks!
