It does act like a strong AM radio station is close by and over powering the
set. You can get "contact rectification due to bad and corroded grounds in
the coax line anywhere from outside pole to the set.Disconnect the coax,
mute it and see.If clears, it's inputting via coax. Disconnect any
audio/video cables as well and see. If still there, wrap the AC power cord
tightly around a ferrite core (old flyback core).Put it in video mode to see
if it is passing thru the RF/IF circuitry.
