Ok,
So I rebuilt the HV section of my PS. Before I did I had dimly lit displays, but garbled. After the rebuild the HV was +74 and -74. Did some poking around, I ordered the 1.2 k resistors for R2 and R4, I replaced them with the original 680 ohm resistors and the voltage came up to +94 and -94.
Sounded ok to me, plugged the display driver board in aaaaannnnnddddd nothing. Not even a faint glimmer.
Probed around some more the - supply was cycling about every second from -34 to -89. The plus was solid +91.
I unplugged the displays, no change, then each of the plugs to the cpu, when I got to j10 on the display driver the fluctuation stopped.
I plugged it back in and unplugged 1j3 on the cpu, still a solid voltage.
I have not gone any further at this point just wondering is someone else has seen this before or could share a tip.
