Do you mean pin 2? It doesn't hook to pin 3.
What do you measure for voltage at the jcn of R41 D2 to ground?
Is D2 a zener diode? If so what part number is it?
Did you buy a new one or re-use the old part?
R41 should be 120 ohms. brown red brown gold
Right?

Hey Bob, I've got thee two measurements, and they are OK. But it seems like the point R41 - D2 doesn't reach directly IC5 (measurement show a resistance of ~5k between R41-D2 and IC5 pin 3)
The definition of the bottom layer isn't enough to see were the pin goes. I'm waiting on the picture of Jed.
