Steps down the high-voltage DC bus into lower voltages required by the TV chassis (commonly 12V and 24V rails).

You can hear sound or see a faint image with a flashlight, but the screen remains black. High-value resistors (1–5 MΩ) in the startup path

: Fuses, varistors (MOV), X/Y noise suppression capacitors, common-mode chokes, and a primary bridge rectifier diode.

: This is where power enters. It uses fuses, varistors (for surge protection), and a bridge rectifier to turn AC into a rough DC signal [6]. PFC (Power Factor Correction) : High-end versions like the Whether you're working on a repair project, designing

Without the , this repair would be impossible in under 6 hours.

Steps down the high-frequency AC from the transformer into stable DC voltages.

Regulates input power to provide a stable 400V DC output. It utilizes a PFC controller (often the FAN7529 ) and a MOSFET to improve efficiency.
