Pins 13,15 of the 3525 go to a 2N6715 transistor .
On the emitter and base I have 0.00 volts
On the collector I have 13.80 volts .
Wondering if it’s bad
Is there a transistor I can put in to replace it for testing ?

That fixative on the caps it likely conductive and corrosive at this point.
Is the transistor shorted?
Is DZ3 shorted?

Is DZ3 shorted?
The transistor and diode (ZD3) test fine out of the board .
Should I remove the caps and clean all of that glue off the board solder the caps back in and see if it will power up ?

I cleaned the fixative from the board and still don’t get any voltages on the 3525

Check DZ2.
Post a photo of the area around that diode and surrounding components. I need to be able to read the values.

What is U6. I can't read many of the values due to bad lighting and resolution.
Give me the DC voltage off all of the terminals of U6.

The collector gets its voltage from Q35
I replaced Q26 and still have no voltage on the collector .
Is there a transistor I can put in place of Q35 2N6715 for testing ?
