Bt am60-550

OK, here are my findings with the bars on my TV's. Like I said I have recapped the BT modulator, that greatly improved the picture quality but also made the bars that much more visible. I have tried an isolation transformer, I have tried reversing plugs to try and get the commons all in the same place. I went into my panel where the cable feed comes in and tried without the ground connection and with the ground connection, no difference.
I found the problem by accident, I was working on trying different things and I moved the antenna and when I tried the set out I noticed the bars were not as noticeable. So I moved the antenna about 10 feet away from the BT, no more bars, perfect picture. Must be some kind of signal feedback with the antenna to close.
Hope this works for anyone else having the same issue.
