This typically indicates an overload or a short circuit on one of the output rails, often due to faulty diodes. Backlight Issues:

If voltages are pulsing (hunting), it often indicates a failure in the feedback loop or the oscillator driving the MOSFET not maintaining continuous oscillation. optocoupler feedback components. Reference Resources 17ips72 schematic work

Regulates the input power from the mains to provide a stable +400V DC output for downstream components. It often utilizes a FAN7529 controller chip and a dedicated MOSFET on a heatsink. This typically indicates an overload or a short

If there’s no standby light, the schematic points to the primary side. Diodes often short out, or the main fuse blows because a MOSFET has failed. 17ips72 schematic work
