Cable TV operation

[sightseers]

We have a 2008 sightseer with Jensen TV and radio/cd/dvd player. Can't get the TV to pick up the cable input. This had worked in fall on our shake down cruise. Have checked the cable signal to the motor home and checked the cable to the back of TV and all is good. There is only one RF cable into the back of the TV so, some where there must be a coupler that connects the cable and the antenna to one port. On this set up, you select cable or antenna via TV remote. On the cable input it picks up a weak antenna signal. Any ideas on what problem might be?

From your post, I would guess you don't have a video selector box. If that's the case, you need to find the switch plate that controls power to the antenna amp. It's probably in one of the front overhead cabinets. Switch off the power to the antenna amp and it should switch over to cable input.

That switch is most likely on the other end of the antenna cable that hooks to the main TV. As Tom said, it not only turns the rooftop antenna amplifier on and off, causing most folks to call it the amplifer (it's not, it's the power supply is all) but it also switches between park and cable

You also need to re-set your TV to cable.. Shortly this last step will no longer be needed.. but till June you still have to do it

On our 2006 Sightseer, we had the same problem. Our dealer installed a switch box, on a charge basis, of course, and that solved it. I didn't know switching the antenna amplifier (power supply) would do the same thing until I read this thread.

The switchplate in our Sunova (Sightseer twin) is located over the passenger seat close to the windshield. It is a very small button beside a 12v (cigarette lighter-type) plug. Had the same problem once and after pushing the button the cable worked. Good luck and let us know if it doesn't work. Eric
