Hi-

So I been trying to follow you guys on this one, I assume this tv is this schematic
https://www.earlytelevision.org/pdf/...s30_manual.pdf

I see you are not getting the -100V source... So my question is are you getting
the 135V source, or is it high? If its high then R186C has to be open, or the
ground lug is not making it to the chassis....?

If the 135V is ok, then I guess you could possibly have
an open R240?? anyway they deserve a sniff...

What is the +275V source reading?

If the 275V is missing, then you have to look at the path through R181, R211.
But then you say the tv has stuff on the screen..... so 275V is there....

Or am I just off in left field here....
