I think this set is fixed. I cleaned some "gunk" (with steel wool) off
the male end that plugs into the tuner. I also soldered all the
connectors, IC's, and the tuner just to make sure. Took it back and it
worked fine. My gut tells me that it was the connector going into the
tuner that was at fault. Only time will tell.

kevin try the part the the rf cable plugs in to the tuner , If the
center of
the plug is too wide then you will have intermittent interference.
hope this helps
