Schematic _hot_: 17ips72

Converts the transformer output back to low DC voltages.

Use an isolation transformer when measuring live voltages with an oscilloscope on the primary side. 17ips72 schematic

Steps up voltage specifically to run the television's backlight array. Common Failure Points Converts the transformer output back to low DC voltages

Check the main fuse. If blown, the primary bridge rectifier or the PFC MOSFET is likely shorted. 17ips72 schematic

Boosts and regulates the DC rail to roughly 400V.
