Hi all:


New to the forum, so please be gentle. This is a cross-post from the "Home Theater General" forum, my apologies in advance if cross-posting is a faux-pas here.


I have a faint line that creeps up the screen whenever using the Svideo input on my TV. Starts at the bottom, and slowly works its way up to the top, then restarts at the bottom. The whole cycle takes about 60 seconds or less.


It's a Panasonic 32" standard tube television, about 3 years old.


I don't notice it when watching standard TV over cable (using the internal tuner).


When using DVD, it is one line. When using the S-Video out on my PC it is two lines evenly spaced.


Here's where I need your help. I'm theorizing that it might be interference creeping into the cables. The DVD to Receiver and Receiver to TV cables are "okay" quality I think (Acoustic Research cables). The PC cable is 15 feet of bargain-bin SVideo cable so I'm definately going to replace that anyways.


Questions:

Think this is my cable? Or might it be an issue with the TV or Yamaha receiver?

Is Acoustic Research cable any good, or should I spring for something slightly more rich (Monster cable?)


Thanks,

Pete

It sounds to me like you either have a ground loop or the 'bargain bin' S-Video cable is picking up interference from an AC power line.


A better quality S-Video may do the trick. AR cables should do just fine. No need to spend a lot of money.


If a new cable does not resolve the issue, do some searches on the forum on 'ground loop', 'hum', etc. This has been discussed quite a bit.
