Cable TV problem

We are connected to park cable. The large TV on the televator gets 28 stations after doing an auto search ( tried it a few times). The bedroom TV and the overhead one in the cockpit both get 58 channels. I haven't checked the outside TV yet. Coax going into the televator TV is tight, I'm thinking maybe there is a loose connection on a splitter somewhere. Any idea where the coax is routed and where teh splitters are ? 2013 DS 4338
Thanks

Is the TV configured for Antenna input?

Check to make sure you are scanning both analog and digital. At the end of scan most TVs display results as digital found = X and analog found = Y.

Not sure if ours is the same but the splitters for us is under the sink against the back wall. Not sure how they run the coax cables. We also get a different amount of channels on the different TV's but nut the spread that you are getting. Typically it might be just a 2-3 channel difference.

Thanks- that's where mine is too. You need to be a contortionist to get to it. I checked an the connections are tight, so, when I get home next week, I'll dig into it further.

update- so I got out and checked the outside TV, it too had limited channels like the televator TV. Both TV's are off the same splitter. I guess the splitter or the feed into the splitter is suspect. There must be 1 or 2 more splitters somewhere that feed the other 2 TV's that are working OK.

I'd tend to think the splitter is fine. I'd look closely at the auto programming instructions for each tv in addition to the comments already made.

Run a coax directly from the outside TV to the pedestal and see what happens.

no issue with autoprogramming. All TV's are the same and I've had them for 5 years. This just started on the 2 tv's - others are fine

Good idea- I'll give that a shot later.

I have the same problem all the time. I am at Newmar and they will be installing a new splitter with a signal amplifier that I purchased off of Amazon. Many times the cable at the CG is split so many times the signal is weak coming into the coach. Split it 4 ways with a long run of coax and the signal is too weak for the TVs to pick up. I will report back once it is installed and we have tried it at a CG...

I have the same issue with my bedroom tv. I have found that it depends on the RV park we are at some work great some the front tv gets more channels than the bedroom. I do agree that the park signal strength has a lot to do with the problem. I think my splitter is in the basement on driver side about the 3rd or 4th compartment back.

I have a 2019 Canyon Star with similar problems. I would imagine gas and DP TV wiring are the same. Here's what I tracked down.

The cable connector from the rear of the coach is connected to the input of a 4 way splitter located next to the televator. Output 1 of 4 is connected to the outside TV, output 2 of 4 is connected to the televator TV and output 3 of 4 is connected to the input of a second splitter located behind the overdash TV. Output 4 of 4 is not connected to anything.

On the splitter behind to overdash TV, output 1 of 4 is connected to the overdash TV, output 2 of 4 is connected to the bedroom TV and outputs 3 of 4 and 4 of 4 are not connected to anything.

Leaving splitter outputs disconnected causes a good bit of signal loss and you would think that Newmar engineers would know that. Splitter outputs should either be connected to something or properly terminated. I elected to replace the 4 output splitter with a 3 output splitter at the televator and replace the 4 output splitter behind the overdash TV with a 2 output splitter. That fixed my problem.

Here's an article. Maybe someone should send it to Newmar.
