How to Diagnose Power Supply Failure?
- The following situations may cause this issue
- Case 1: The LED on the power supply does not light up; Case 2: Amp/Preamp does not turn on; Case 3: When plugged into the Amp, both light on the amp & power supply start blinking; Case 4: Amp/Preamp make noise; Case 5: Sound shuts off by itself
