Hello all,
Over the past year I have assembled a mini home theater on a budget for the master bedroom. This setup includes the following. 27 inch JVC AV27F802 flat tube, Sony 715p DVD with mc video 3 component cable, Denon 3300 receiver, pinnacle digital sub 150, polk audio rt35i fronts, rt25i rears and a c245i center. For the amount of money put into it, it blows my mind.I also have a mc HTS 800 power conditioner theat everything but the dennon is plugged into. But not all is well in Home theater land. I have noticed that during dark scenes, those with low lighting/contrast, there are sometimes these wavy horizontal lines that appear. They move around the screen like ghosts, shadows if you will. On scenes with high contrast/light, the picture is remarkable. The colors are amazing, detail is great. But whats up with these faint horizontal lines that dance on my screen in darker scenes, i.e. ending credits? it is not speaker interference, i took them away from the tv and they remained, I also paused the dvd when the lines appeared, but the lines continued to move. Any thoughts on how to correct this? Could it be something invoved with the cable? WHen i shut the cable box the lines remain as well. BTW, the cable line is also ran through the power conditioner too. Thanks again everybody.

Follow Ups:
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.
Good luck . . .
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!!
