Larry,
I had similar symptoms after replacing the fbt for this same chassis. It
turned out to be an incorrect replacement fbt. There were two different
upgrades
listed, one of which was incorrect giving full deflection, low HV and glassy
image.

<< seems like g2 is ok,
i now suspect bad jungle IC feeding video output ic on crt board.
output voltages from flyback windings seem ok, just hard to
except 2 different problems at same time. draws very low
current, smp in up to power, but still shut down in 10
seconds, with hardly any light on screen.
I am giving up on this one, cant see gambling and changing
that 4 sided ic.
lol
thanks all,
Larry
