i reinstalled the HOT then tried the 1k resistor on the R G B pins
and nothing happened. measured the voltages of R G B and found 88v
measured G1 and G2 on crt neck board found G2 at 0v but G1 was -23.
G1 continued to drop to 0v. if i switch the monitor off/on i get
voltage at G1(100+volts then it drops back to 0v)
it sounds like the monitor is shutting down after switching on.

(tried the resistor on a working monitor and screen went
blue/red/green, G1 and G2 voltages 273v and -27v)

You should check to see if you have drive pulses to the base of the
horiz output transistor, and to the HV drivers that are the output of
the HV generator. This is the next step.
