My Atari 800 has developed a problem. It is used with a TV as opposed to
a monitor , and the problem exists when all peripherals are disconnected
and unplugged.  Bars of video distortion and noise (horizontal) drift slowly
thru the screen at a steady rate.  The bars (only one at a time) occupy
about 1/5 of the screen, and the remainder of the screen looks less sharp
than usual.  Inserting  and removing  a program ROM a few times seems
to clear up the problem, but
the next time the computer is turned on, it is likely to be back. Looks like
an interference problem to me , as I get the same results on another tv.
Is my modulator dying?  Bad grounding somewhere?  Has anyone else encountered
a similar problem?
