I have a 1995 Sony Trinitron 32" TV, model # KV-32S16.

The problem is the TV seems to work fine. After a few minutes the whole
entire TV shuts off. You have to unplug it for 10secs or so and then you
can plug it back in and it comes back on - wash, rinse, repeat.

Any ideas? TIA

One more thing: Right before it shuts off the screen goes completely green.
At one point I turned it on and it was all green and then finally shut
itsself off again.

TIA

Common problem, bad picture tube.
Slim chance the intermittent short can be blasted out of the guns in
the tube by a proper crt rejuvinator short removal feature.
More likely it will need a new picture tube in order to permanently fix
the issue, not cost effective.

Ok I sounds right. Tell me what you think of this please - I pulled the
neck board off and the TV stayed running (had high voltage, etc).... This
is definitely signs of a shorted/bad tube correct?

I've repaired quite a few of these using a crt filament isolator available from MCM and other distributors. Chuck
