Topic: Can you give me some advice on zener diode (Read 15 times) previous topic - next topic


Hi, I am a total novice when it comes to circuit boards and was wondering if someone could help me. I have a Horizon Omega CS treadmill and there was a loud bang when I plugged it in last week and the circuit board had blown a couple of transistors and a couple of zener diodes. As the diodes have blown, I am unable to test what voltage ones I would need to replace them. I am attaching a picture and would be really grateful if someone could help me. I have looked online for a diagram of the circuit board

Thank you
