In Reply to: Do I have an interference problem? posted by Parasound on November 17, 2002 at 20:12:34:
I had horizontal lines of darker and lighter charcoal gray in dark scenes. Turns out it was faulty design, a bad power supply in the Magnavox 32" TV I had. Returned it to Sears for a comparable Panasonic unit and have been very happy since.May or may not be the case in your situation, but if it is, it's probably unfixable. If the TV is still under warranty, a tech may be able to help; and if he can't, it's grounds for a return or credit toward another model. That's what happened in my case and it's worth a shot.

try disconnecting the braodcast TV cable and then play a DVD through another input...problem still there?
disconnect the coax-cable at the HTS800 also.... IF it's a ground loop, the problem will likely be there whether the cable box is on or off..... it's a voltage differential between the ground for the cable and your system....IF disconnecting the Coax cabel works then you have a few options:
1. find the place where the cable comes in to your house and ground ground it to the same source as your house is....
2. get a ground-loop breaker and install it prior to the HTS800...NOT AFTER!!
