you can force the deflection Ay on, by shorting tp210 (location G-2) on the
deflection pcb. I don't reccommend it since mine took out the H-out after a
couple of tests.
Me thinks the issue might be with the SMPS running slightly overvoltage. It
wants to sit at 160v rather than 137v, which might be enough to invoke
shutdowns and smoke the H-out with a reduced crt load when forced on(as I
had done).
It was not clear to me what might cause this.

another shop (tech there gave up on it, smart fellow). Anyway, have removed
crt boards, disconneted connectors listed in "circuit overview", shorted B-E
of TV852 and still no dice. Pulses 3 times but turns off so fast I can't
locate trouble. b+ good, verified by lifting C of horz xstr and shorting B-E
of TP210. I welcome any ideas or suggestions.
