Given the lack of specificity, here's a simplified conceptual schematic:
The "brains" that control the timing of the pulses. The secondary side rectifies and regulates the output
: If you experience "no power" or "no display," the most frequent culprits are blown fuses or faulty capacitors .
Finding a reliable schematic for specific bench power supplies like the can be a challenging task for electronics hobbyists and repair technicians. These variable DC power supplies are popular in repair shops for their affordability, but official service manuals are rarely published. : If you experience "no power" or "no

The device completely fails to power on; no standby lights.
A bridge rectifier converts the AC voltage to unregulated DC.
Schottky diodes and low-ESR electrolytic capacitors convert the transformer's output back into stable, low-voltage DC (commonly 5V, 12V, or 24V).
