ghellmold,
I'm not trying to be a wise guy, but instead, ask a question: are you using an HD antenna?
I'm not sure that we can control the power and frequencies being broadcast in your area. That said, let me know and I'll see what I can do to assist you further.

I have a digital signal problem with Samsung LN52A860. Analog signal and other sources work fine but the OTA digital signal frequently causes the TV to pixelate, sometimes display weak signal, etc.. Have had this problem since I purchase in October 2008 but its much worse now.
Samsung came out and replaced the main board (which includes the tuner) but still same problem. The technician suggested that I check the cable line to the antenna. So I installed new quad shield cable, used high-end connectors and routed the wire away from any electric or anything that could interfere. I use no splitters or couplers. I shut the breakers to all electric outlets in the house except the TV outlet. I tried other electric outlets. I also tried installing a signal booster and installed a high end surge protector. I still have the same problem.
I have a clear view of the stations' transmitters 19 miles away and tried various low and high end HDTV antennas. Same cable/setup works fine with external tuners, my Samsung LNS4695D and Vizio TV. Just will not work correctly with this 52" Samsung.
Any suggestions? Is there any other parts in that TV that would cause the digital tuner to work poorly? Does the 8 series have a known problem with its digital tuners? If so, how do I get a refund from Samsung since the retailer will no longer accept a return?
