Jonas, I don't believe you can disconnect the crt board to test on a Sony as
it will cause shut down. Maybe if you disconnect the hv anode at the block
to the green crt and try to power up.you may have to disconnect focus lead
as well.

> Hi all,
> Did a service call on the above 1991 Sony projo, when power is pressed the
end of the green crt glows violet for a second then shuts down. Is this a
sure indication that the crt has gone bad or is there a chance that there
might be another problem in the video circuit. This tube is going to be hell
taking out and installing so I would like to be as sure as possible.
