1 TV out of 3 work - confusing..

Hello fellow IRV2ers,

FIRST POST - We recently purchased a Newmar DSDP 4018 - (New)

Our issue: ...

3 TV's - On Cable input - The Bedroom TV received 35 of 45 available channels - Programmed correctly per campground instructions - followed suit on other 2 TV's and got 4 channels on Main TV and none on outside TV...

Checked all connections on the splitters (all tight) - re-programmed all tv's (nothing seemed to help). Campground maint. assisted and checked main connection to our rig - (line from CG - perfect all 45 channels on their IPAD)

Re-checked all rig connections and verified that the OTA antenna was off per instructions - still no luck.

I have been watching these forums for quite a while - and have tried some of the possible fixes that seem to pertain to our issue.

If any of you have possible fixes - I will attempt anything at this point. I could bring it back to the dealer - 3 hours away. want to avoid that.

(FYI - have travelers on roof - not set up yet, made sure their connections were snug too.)

Thanks to ALL

Using splitters isn't a good way to send a signal to 3 TVs. If the campground has a weak cable signal at your site, you will then further weaken it by splitting it. Splitters come in all different grades, they all weaken the signal a bit, but some are better than others. You may want to install an amplifier in the RV to boost the signal before splitting it.

The Channel Master splitter and amplifier might be something to add to your system.

SLAMX2 get a long enough coax patch cable and run from the park post to each TV this will tell you if it is a TV problem or a cable in the coach problem.

There's a chance that your campground uses digital cable and that one or more of your TVs does not have a QAM tuner (necessary to receive digital cable).
