I desoldered Q101 and i reconnect the 12v zener D102
and the resistor R112
and I measured those voltages on 358:
1=6,32v
2=6,37v
3=6,36v
4=0v
5=0,74v
6=1,752v
7=11,49v
8=12,7v
Have I to resolder just the q101 now?
It looks like the 358 is faulty, but you should try pulling pin 5 high/low while watching
pin 7 again - see last part of my previous message. Also the bit about pulling the 9142
pin 11 to pin 1.
