Our new to us 2011 Montana High Country 343 RL has a 12 volt television in the bedroom. When I turn it on the screen says run auto program, and after I do that it comes back and says the same thing. I cant get any channels. I tried another tv in there just to make sure the antenna hook up works in the bedroom. So I believe there is a problem with the tv. Has anyone else had this issue
 
Have you first chosen air or cable? And if you have chosen air you must turn on antenna booster located where the cable plugs into the wall. If these two are correct, you must have a TV problem.

Larry has some good ideas. Try them and let us know if they solve your problem. ;)
 
I would suggest that you have a signal problem, TV is fine. Your TV is telling you it can't find a TV station signal. As Larry stated it could be that your booster is not on and/or that you need to go in to TV settings and set it to air if you want to use the roof top antenna. For satellite use it must be set to cable. If these don't work it could be how your cables are connected from the wall to the TV, or even a bad cable somewhere in the system.
 
Perhaps a programming issue? When we turn ours own, we just get fuzz. No commands like you described. Jensen 12 Volt. We then hit the menu button and several programming options come up, to include the air cable options Larry referred to. After selecting one or the other, then auto program is next step.
 
Everything Larry says plus check that the jumper next to the button to turn on the booster is connected to the right jack. On our 2010 both TV's were a pain to get programed right, and they both programed differently but once we got it done they've been great ever since.
 
Since gmseller said he has tried another tv and it works, then the problem has to be with the 12volt tv. I suggest he try to see why the 12 volt isn't working properly, going with the program setup.
Make sure the tv is set for the antenna. If it still has a problem, you may have to have the tv checked out.
If the other tv works, the jumper is correctly set.
 
I have tried air and cable option and still keeps coming back to run auto scan, even after i run auto scan. Booster is fine bc the other TV works in the living room and I brought one from the house and that one works too
 
Our Jensen DC television in the 3750 was very finicky with the coax cable connection. That would be the only other thing to check that I would know of. You may get help from customer support listed on Jensenrvdirect.com.
 
Way back up in this thread KDEISS suggested that the 12 volt TV might be the older Analog type receiver. If there has been a response to this, I must have missed it.
 
The Jensen tv's that were introduced as the "bedroom" tv in the 2010-2011 time frame (not sure about 2010, but our 2011 3750FL had one), were HD LED digital televisions, not analog.
Bingo
 
Take that Jensen TV into your home and hook it up.
Now, see it it works at home.
If not it's probably the TV.
If it does, it's back to the dealer and get it repaired by under the Montana warranty.

P.S. I have the exact same Montana!
 
When it comes back and says autoscan does it give you an option to exit the program mode? Perhaps you need to exit that mode before you can view the channels the scan picked up. Just fishing for things to try. Jim
 
We have the same Jensen TV in the bedroom and initially had problems with it as well. It turned out to be a poor connection at the plastic box where the power and signal come out of the wall. Things are very tight in there but I managed to get a little extra slack on the cable from the booster. I replaced the short cable to the TV from this box and have had no problems since.

Because mine was intermittent it was a little tough to diagnose. When you hooked up the other TV and found it worked did you use the cable out of the wall that feeds the Jensen. Your problem seems to be signal related as in no signal.

You could check the continuity on the cable where it connects to the TV, back to the booster in the closet to confirm the cable is ok.

A bit of a challenge to check it in the house unless you have a 12V supply there.
 
With the jenson tv's, it does the auto scan, then with that working it will memorize the channels found. My tv has worked fine except for one time when it failed the auto scan and thinking that was odd, I looked underneath the bottom of it and saw that the tiny coax cable into the tv was out. Plugging back in solved my issue. Failure to auto scan can only be the tv or no signal feed to the tv. john
 
I put the camper away for winter but i took the tv out and going to try it in the house. I just need to find a 12 power supply in the house. I have a converter at work i can bring home to plug it in. I will let you know how it works
