Fuzzy Picture on 1 TV

[UFO Pilot]

The TV's in my MH have always had a very good picture. I brought it home from storage today and the Bedroom TV is very fuzzy. I have DISH service with 1 receiver and a KingDome satellite. I have reset all of the buttons on the input control box and still have a fuzzy picture in the BR. Any ideas on the problem and or what to check?

If you have one TV that is OK and one that is not, it's not the dome or the receiver. If you have a Winegard selector box, switch the bedroom TV back and forth from Sat to another selection a couple of times. If that doesn't fix the problem, I would then check all cable connections to the bad TV. Also, make sure the bedroom TV is on the proper channel (3 or 4) for your receiver.

It has to be a bad connection and/or selector switch.

I agree with ELK, if it has always been good, and now it's bad you have a bad cable

I recommend you do a three step check
'
First check the cable ends in the bedroom (This may involve removal of the tv) you should have 3 ends there.. One is in the wall behind the plate, Make sure none of them have pulled off, make sure the center wire extends slightly beyond the nut... If not.. Re-do the end using a good compression fitting and tool.

Step 2: Check the end at the switch box

Step 3: If all ends are good.. Replace the cable with RG-6

NOTE: Dish uses UHF for the 2nd TV.. I find that with my hookup I got very good signal on UHF in the front but snow in the back ON chan 3/4 it was Good/Good

Another thing that can bother your rear tv UHF picture is where you are parked.. The cable in my rig is not all that well shielded it seems and I often have to change my TV-2 UHF channel on the Dish Receiver to avoid interference

Today's Digital TV transmitters are mostly (not entierly) on UHF so you may have to Channel Shop a bit, Also the channel displayed on a digital TV is usually NOT the channel on which it's broadcast

For example.. One place I parked 13 was indeed 13, but 4 transmitted 36 and 62 on 45, Where I'm at now chan 2 transmits on chan 7

Thanx for all of the replies. I checked the coax connection at the TV and it was good. I removed the Winegard selector box and checked all of the connections and they were tight. I went to check the TV and it was clear as a bell! I remounted the Winegard selector box and the picture is still clear. Didn't do anything really, but the picture is good again and all is well.
