tv cable issue with 2006 tourmaster T40A

[babyrattles]

All HDTVs in motorhome, must run cable line directly from outside cable box into splitter next to TV above passenger window, when I run the cable line through the connector in 30/50 amp storage box, some of the channels are snowy. Cable company did line test today, their equipment is OK.

On my 07 Tourmaster, the cable and satelite connections are reversed in the electrical compartment. The cable connection is the one under the small box with a lid which also includes the telephone hookup. Others have had the same issue.

Don't forget to turn the antenna amplifier OFF. It is the red light on the wall plate near the entertainment center. Press the black button on the wall plate to turn the red light out.

I have had this same difficulty with snowy picture.

look for badly installed coax ends, as I understand iti, it only takes 1 tiny wire from the braid touching where it don't belong to ruin the pictures!
