Over the air reception question

Hook the bedroom TV up to the connection used by the other TV. It's the wiring if it gets the same channels as the other TV, The other TV if it gets more.

Maybe 9 analog channels and 20 digital channels? (old tech TV vs new tech)

Plain and simple........Difference in quality of digital tuners in each TV.

Probably what others have said, but....
might double check the connections in the coax cable from the back of the TV and to where it connects to the splitter box and make sure the connections are tight and that there are good amounts of center conductor (copper center wire). The splitter box could also not be sending the signal very well. I agree with others that Jensen is not the best brand but I am a little surprised that there is that much of a difference.

Oh come on guys, the RV salesman said it is an RV television without any moving parts and rugged enough to withstand the banging around in an RV. Surly he must know what he is talking about, he's an RV salesman.

Okay, that was a slam on salesmen. So here is what I did, went to Best Buy and bought two Insignia TV sets and they always work and cost half of a Jensen. The viewing angle is great and the DW or the DGKs can change channels for me from the bedroom.

Oh! that's not good is it, messing with the old "GDude".

The quality of the tuner & other electronics in the Jensen is rock-bottom, producing a very poor signal/noise ratio through the TV.... therefore no picture.

Brand. Replace the Original Equipment one with one from Walmart. OEM stuff is designed for Manufacturers to install cheaply. If it works, ok. If it doesn't work very well, that's OK also.
