Tricky tv

[SteveSkinner]

Here is one for the experts
Tv in the front of the coach works perfectly on cable.
The bedroom tv works perfectly except that sone channels have no sound
I can't figure it out.
Nothing I do will change this

In today's digital world.. you have a problem with the TV.. If it is an analog set, then there is a possible answer.. But in the digital relm, you either get everythign, or nothing.

That said.. As the signal weakens.. Sound usually goes before picture.. Might be bad coax. But I'd expect video issues in addition to audio (Pixleation and tearing)

Disconnect coax from front TV and use extension (your park hook-up cable should do) to connect to rear TV. If problem with rear TV still exists - bad TV. Rear TV OK on extension - let us know and we will have to think harder.

I have sound on the rear TV on Satellite and Cable, but no sound when using the Batwing. I can't seem to find the problem either. I have pushed every button on the remote but nothing fixes it. I can't believe it is a bad TV when the sound works on 2 out of 3 feeds.

Get on the roof and check your connection to the batwing. I recently had similar problems and found the coax had loosened from the connector. Of course, also be sure your power booster is turned on.

The sound works on the front TV off the bat wing, isn't there only one coax connection on the antenna?

Yes there is only one connection. As I said in my previous post, my connection was bad (not disconnected). This degraded the signal strength, which in turn reduced the signal to both TVs. With the extra 35 ft of cable to the rear TV, that could be enough to lose your sound back there.

Failing that, to troubleshoot this, I would do the following:

Hook-up your rear TV to the front cable. If it works, you have a signal strength problem and/or a bad cable running to the back. If that doesn't work, you have a problem with that TV.

I would then check the "Menu" on that TV to see if it needs to be switched between "Cable" and "Antenna" as the current input. Actually, I would check this first.

One other problem I've seen is with these push button video switch boxes. When I bought my used MH, my pictures were bad and had low signal strength. I removed the switch box and replaced it with 1 high quality splitter. The picture quality and signal strength difference was huge. I had two friends with the same problem. After removing the switch boxes, problem solved. Granted these boxes were old and perhaps cheap. I'm sure a new high quality box works fine but, anytime you start adding connections and switches to a video feed, you're going to lose something.
