Have 3 Panasonic tv's on my motor home. When programming all the tv's for OTA antenna reception the tv's doesn't receive the same channels. The front tv will receive like channels a,b,c,d,e, and f clearly, The bedroom tv will receive maybe channels a,c,d, and not the others. The outside tv will receive any portion of the ones programmed to the front tv. I try to do an antenna point via www.antennapoint.com once I set up the RV. (Although the antenna doesn't have an indicator as to where it may be pointing so I just try an educated guess and hope for the best.) Nonetheless, each tv has some independent channels to themselves and not all three. Any solutions from anyone. It would seem to me that all tv's would program and display the same channels. All the tv's are the same model as far as I can tell.

When you go into the setup menu, make sure all TVs are set for antenna and not cable.

If you have a Winegard Batwing, the "front" of the antenna for the purposes of pointing it is the side of the antenna that faces the right side of your coach when the antenna is stowed. Point this side in the direction of the station you are trying to receive. I use THIS ANTENNA POINTING GUIDE to determine the location of station(s).

For antenna reception each TV individually tunes it's channels. The signal is received on all fequencies simultaneously and the TV decodes it. For cable it should do the same thing. Satellite or any other method that uses a central "tuner" or decoder unit (including an old fashioned "cable box" or probably a HD to Std def converter box) will drive all TVs on the same channel, because it does the decoding and selection. (Unless you have a residential type "multi room" satelite receiver.) However, depending on your setup and if you have the IR remote repeater system, it may be possible to have some or all TV's select the same, but that's only due to the IR repeater telling them all to do the same thing at the same time.

I believe all your TV sets are connected by HDMI cables to a central distribution point. You need to locate that distribution box and check the tightness of all the HDMI cables. I have one cable in my Phaeton that had a cracked connector and was loose causing a problem such as yours. Once I located the box and found the cracked connector and repaired the connection the problem was fixed.

Also don't rule out a simply bad tuner on the one TV in question.
