I've got a Yamaha P7000S Power Amplifier on my desk. It is not powering up. In general,can anyone please advice me on steps to find faults in SMPS?
To be more specific on the problem here, Two power resistors were blown and also two igbt close to the main transformer were blown.
Please help. Thank you
