Coleco Telstar Arcade Repair Help


Recommended Posts

I am in the process of repairing a Coleco Telstar arcade which would not power up. There is a simple voltage regular circuit in the corner of the main board which wasn't working. I replace the bad Q2 transistor, but then the CR3 zener diode burned out. Unfortunately it burned to the point where I can't read the part number. I can see IN75 but not the last two digits which are the ones that indicate the operating voltage. I also have not been able to find any schematics. I was wonder if someone has one of these if they could read the part number off that diode, or take a voltage measurement between the two points circled in red in the second picture.
