FSP 271-4F01 TV Power Supply Repair Service

Professional diagnostic and board-level repair service for this FSP FSP271-4F01 TV Power Supply.

FSP FSP271‑4F01 is a TV power supply board used in Sony/Philips/LG models, featuring a switching regulator and multiple output rails. Common failures include blown fuses due to internal shorts from degraded electrolytic capacitors or damaged MOSFETs; the fuse often blows immediately even when disconnected from the TV. First‑check diagnostics: verify input AC voltage and polarity, test the main fuse and replace if blown, then visually inspect for bulging or leaking capacitors and any solder bridges on the board. Next, measure output voltages with a multimeter while the supply is powered (but not connected to the TV) to confirm regulator operation; finally review any error codes or LED indicators on the host unit that may point to power‑supply faults.
