Ed, I have 10.00 bucks, (US) that says you have a bad CRT socket with a
scorched spark gap. You have to take it apart to see. If you have a very
small voltage on the wire from the fly, maybe 1.5 or 2.0 and zero on the
socket pin, that is the clue. Also with the wire from the fly disconnected
from the CRT socket board the screen voltage on the wire will be normal.

Would someone have a Manual on this set. Particularly the Sweep ciruit.
This set was originally Dead.
Replaced Flyback 237506, Got HV and sound back. But seems I have no
Screen Voltage. (Zero). So of course I have no raster. I have tried a
second flyback, thinking a faulty transformer, but same result.
A Circuit and any suggestions appreciated.
Thanks;
