Why is my cable TV fuzzy?

(1/2) > >>

We've got cable TV installed on two TV's in our house - both standard def TV's.  It's not digital cable or anything.  We have the network channels and the 60 or so standard cable channels like A&E, FX, etc.  On one TV the cable channels look fine but it's a standalone TV/DVD combo in our bedroom.  On the nice TV downstairs the channels look fuzzy, like there's light static or something.  The actual cable is attached to our new Tivo, which then runs into our Onkyo reciever (which is only a year old) and then it connects to our TV.  Nothing's fancy here - everything is composite video (the yellow cable) but it looks fine on one TV and has static on the other.

Is this a bad install that's causing the picture problem?  Is there some interference problem with my equipment?  Other signals that go through our receiver (DVD, Wii, etc.) look fine so I don't think it's our receiver or our TV.  I can't imagine it's the Tivo as it's brand-new.

What's the deal?  Do I need to call the cable company?

How many splitters are you using?  Is there a single cable coming in that splits to the two TVs, and perhaps an additional splitter to run over to a cable modem?

Troubleshooting 101: start removing parts from the equation and see when it improves.

Bypass the receiver, look good? Bypass the TiVo, look good? plug one TV in where the other one was, any difference? DVD player to the fuzzy TV look good? Composite cabling is subject to cable quality and interference, any other cables available to try? Anything nearby that may be interfering? Anything that's plugged in basically has an opportunity to interfere.

I'd call the cable company-  there should be no charge for them to come out and look into it.  What's happening to you sounds like something that happened to me before- we had a fuzzy image for several channels and when the cable guy came out he found that the guy who installed the cable had not properly shaved off errant bits of coaxial cable when he had cut it and put on the plugs.  the result was that there were bits of cable sticking out of the end and they were picking up local broadcasts that interferred with the signal.  The new guy recut the cable and everything was fine.

I would verify this before scheduling them to come out. I know more than a few cable companys will charge you if they determine the fault does not lie in their equipment/cable line.
