TV interference

The TV in the living area has little diagonal lines on the screen. Same show on bedroom TV, has no lines.

Should I suspect interference from the converter/charger? I shut down all users, except the TV, sat, receiver, converter/charger, and 110v. on refrig. No other 12v. or 110v. in service.

Any ideas?

Have you tried a different TV in the living area to eliminate the TV itself from being the problem?

No yet.
I will be snooping it, tomorrow, if not raining.

I had problem with my TVs when I first got the 2005 29 RLBS. problem # 1. was the Splitter was installed backwards. I had to remove the wall panel to the left side going up to the bedroom. I removed the Panel and changed the splitter to the right way. I also found that the Ant. cable had two staples stuck into the cable. The cable that they installed in my 5th wheel is not of the best grade.

I went through and changed out all of the connecters to the new crimp style.
