Sorry for posting if this is redundant, but I searched the forums and couldn't find anything on this problem. I have a 622 and am pulling Columbus, OH locals via an antenna on my roof. I've never had any problems pulling locals, and I have the locals split and going both to the 622 and to the HD tuner on my tv. I noticed this afternoon that the only locals I can view on the 622 are channels 6-1 and 6-2. 4, 10, 28, 34 do not come in at all on the antenna, I get the signal lost error screen. However, when I go over to my TV, I seem to be getting those channels fine on the tv tuner. I have tried unplugging the box, but its still the same!! Is anyone else having this problem? Any suggestions??
