Panasonic HDTV Not Picking Up Digital Channels ABC, CBS

by JC-15 / March 28, 2011 2:29 AM PDT

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?

You need an antenna

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)

Got it Working

I moved the Panasonic to the great room where the Sony is and re-scanned the channels. ABC, CBS, and all the other channels showed up perfectly. Took the Panasonic back to the bedroom, hooked it back up to the cable jack and everything is working great now...all available digital channels showing.

Thanks again for the feedback.

New Development: ABC, CBS show up on Panasonic in Great Room
by JC-15 / March 28, 2011 10:20 AM PDT

Thanks guys.

Here is an interesting development. I hooked up my Panasonic to the cable jack in the great room (where my Sony is) and bingo, ABC and CBS showed up perfectly along with all the other digital channels.

Does anyone have experience with cable jacks to help me understand why one would deliver all the channels and the other would keep ABC and CBS from coming through? The great room is closer to the outside cable box by about 11 ft...not sure if that is making a difference, especially in light of the fact that all the other digital channels show up just fine in the bedroom.

signals were below a threshold

My understanding of digital vs analog is that you have to be at a minimum signal level for the tuner to work properly. In the good old days you could at least hear the football game even though the picture was all snow. Not anymore...
