I apparently found the problem on this set. I say apparently because
the problem was very intermittent but it has played for several hours
without problem. The problem was IC750, a 9v regulator in the standby
power supply which is also the horiz Vcc. When the problem occurred the
output would go HIGH to about 10.6 volts. After more checking I
realized the green was not dropping out but mearly shifting the tint.
(faces would go purple). Ain't life fun? John
