Jose,

Measured voltage for IC10 are:   pin  1  ~ 8   : 1=11.7  /2= 11.7 / 3=11.7 /4=0 == 5=3.3 / 6=2.31 / 7=11.7 / 8=11.7   (Volts)
But, perhaps I should just replace the IC rather than
wondering if it's good or NG.
The voltages seem to indicate it is good. Pin 6 is much lower than pin 5 even though it is fed from pin 7 which is very high.
I've not been following too closely. Have you checked voltages each side of R37? Is C22 installed the correct way round? Is it leaky?
