Yes I have a Amplifier on the Channnel Master Antenna, and have bypased the amp, with no luck. I have hooked up another digital TV at the same location, and had no problem picking up the digital signals, this TV was a 32" Toshiba. Since I have had the same issues with 3 other Sony Bravia TV's, it seems that it has to be something I am overlooking. The Sony wide world help line, was no help at, they were basically reading out of the manual, and kept asking if I had tried this step, and that step per batum, out of the book.
