Your lucky your getting anything from the shielded coax lines.
For 2.1 & 92.1 what is the call number.. In maybe ABC but is could be ABC from 100+ miles away in a different city.
Have you checked the signal strength meter on the tv? Menu>Setup>Ant/Cable setup>Signal Meter
OTA is very picky, a change a weather can make it so you get or not get some channels... Clouds for me I get more channels, some from 180 miles away from here but I still have trouble getting channels from towers just 5 miles away because of hills (I almost never use OTA)
I have a Panasonic TC-L32C22 in my bedroom and a Sony Bravia 40" in our great room.
I recently canceled our basic cable subscription for $25/month because a friend told me that the tuners in my TV's will pick up the local digital channels. He was right.
Running directly from the TV to the cable jack on the walls, my Sony and Panasonic picked up every channel that I was paying $25/month for (the HD ABC, CBS, Fox, NBC, etc.)
Everything was going great for about two days until ABC and CBS vanished. I was able to re-scan on the Sony and it found them again on different channels (example...ABC which was formerly channel 2.1 is now found on channel 92.1 and CBS which was formerly channel 5.1 is now 93.3)
However, these channels do not appear on the Panasonic. All of the other channels are there except for these two. I have rescanned several times but with no luck. If it was a signal strength or tuner issue, I would think that it wouldn't be able to pick up all the other channels so easily.
Any thoughts on what might be causing the problem?
