Hi everyone. My name is James. I'm new on this zone. I would like to ask if you have the diagram of this board and possibly have the value of each resistor and zener diode. Any help will be appreciated. Thank you!
This board came from a power amplifier (a local brand) probably a chinese brand. They called this a stepper and obviously has an issue.

Plus a photo of the components side, description of the fault.
The broken tracks can be repaired with fine wire, soldered across the gaps after carefully scraping off the resist.
