Inspect the optocoupler and the reference voltage regulator (TL431). If the optocoupler fails, it falsely triggers the PWM chip's over-voltage safety lock, shutting down the 48V output rail completely.
Perform a thorough visual check of the board. Look for:
Check the housing for damage caused by overheating, which is a primary reason for PSU failure. Safety Note
