I recently got a 9 year old HLT-3270 32" LCD TV and thought it would be worth fixing.

The Defect

TV will not turn on, no power LED on, no current draw on the mains supply. Mains fuse on the power supply broken.

Power Supply

This set uses a Bentec DMC BP-170AWL power supply according to the sticker on the circuit board. I was not able to find schematics on that particular board.

Key parts:

  • PFC controller: Fairchild FAN7527B
  • PWM controller, switch Fairchild FS7M0880
