Poor TV reception, check the wall plate wiring..

On my coach when new the video did not work right when I tried to feed it A/V Worked ok on RV but I could not get picture when I went the alternate, higher quality in theory route.

Finally I got a look at the backside of the big Toshiba TV The following chart represents the jacks... O= open X=Cable connectd
. . . out.. . .in 1. .in 2.
Video .X. . . . .O . . . O
Left . O . . . . X . . . O
Right .O . . . . X . . . O

Yup, they plugged the vide (Yellow)(lead into the OUT jack instead of the IN)

Same problem, Different pew.

I took the little "booster box" wall plate off ...

Described ad nauseam as such on these forums but nevertheless still inaccurate no matter how many times it's repeated. :S That wall plate "booster box" as you call it has no signal boost capability at all, it merely routes the signal from the antenna head OR from the cable feed on the side of the trailer to the television. When switched "on" it's in the antenna mode and feeds the required +/- 12 vdc to the antenna head which does contain a signal amplifier. When the wall plate is switched "off" the 12 vdc is disabled and the signal from the cable input connector is instead routed to the television. One could of course add a signal amplifier such as the Winegard SensarPro as I have but I don't know of any trailer manufacturer that installs a wall plate with signal boost capability as a stock item.

Sounds like someone before you may have re-routing cables to make SAT TV work for them perhaps...

This is a neat pictorial on how they are suppose to be connected up...

GOOD on YOU! I've seen this before. Met folks with a nice little Winnebago View who'd had "professional" work done on their antenna system. They were converting from old OTA broadcast to Digital OTA and when the "professional" was done, nothing worked but the owner's charge card. They were carrying a 19" flat screen and rabbit ears in a plastic bag. All it took was going to Winnebago's wonderful website, finding the diagrams, and putting it all back the way they planned. Next day I made an adapter to match the VESA pattern from their old TV to the new one. They were SO happy, and all it took was to follow directions. You'd think an RV builder could get people to do that.

For you Lurkers, remember to turn the Power in the Wall Plate ON for Antenna and be sure it's OFF for park cable TV. I've never worked with a portable dish antenna for satellite so I can't tell you what that position should be.
