Yes, I only rejuvenate the picture tube if it tests bad.

Wow I would never clean or rejuvenate any crt unless i was sure
it was bad.
Way too risky for me. I would think the crt would be in a protective
hard
video mute such as could happen if no H or V deflection or open yoke
connection. use a scope, measure the IK, look for video signal
Oh yeah I forgot you said no skem. Often I can hear the vert if the room
is
quiet. Try resoldering the connections on the yoke.

Well Guys I tried to adjust the screen today but also to no avail.
I also tried to rejuvenate the picture tube also to no avail.
Can anyone tell me how to proceed? Is there a way to disable the sony
shut
down
circuit??
My collector voltage is at 203 V on all colours Emitter is at 8.3 on all
as
well...
Is there a test I can do to see why I have no video???
Perhaps there is a schematic in the members area??
TIA
