was using my scope the other day and it just quit showing a trace, so i cracked it open and started looking around, and found the -8vdc rail to be in the mv range.6 volts on pin 3 just means that the feedback divider is working and
the output is 0 volts.
So the output is stuck at 0 volts either because the output of the
regulator is not working or because there is a short on the output.
Measure the voltage across R1468 to find the output current. If the
output current is high, probably about 1/2 amp, then there is a short
on the output which is a common problem; look for a shorted solid
