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
