I once had a similar problem. After all kinds of checks I was up
on the tower and saw the old TV antenna (They had put in cable). The
old lead-in had been dropped through a hole in the floor under the TV
and was randomly coiled in the crawl space. Removal of the old
antenna and lead-in solved the problem. At a previous house the
trouble came from a rusted screen near the TV.
Look for random wires, ungrounded or miswired AC Outlets, and rusty
bits of metal (Downspouts, screens, etc.)
Good Luck
