Cable tv not working

[AnneM]

Cable running from POS to trailer to tv not working.
Cable running from POS directly to tv works.
Already replaced cable connector on exterior hookup...
Is it the internal wiring or maybe the cable/antenna booster outlet?
Please help.

Make sure antenna booster is off (no green light).

Do you have more than 1 TV. If so, it might be the splitter, or the input cable is screwed into an output position of the splitter.I you have only 1 tv, it might be the barrel connector that feeds the rv . Unfortunately, low voltage items such as tv, phone ,and audio equipment are at the bottom of the food chain when it come to QC, I've noticed.
