This side is isolated by the main transformer (T801). It produces 12V, 24V, and 5VSB.

The board has four distinct functional blocks. If you do not have the schematic on your bench, memorize this topology: Without specific details on the TPV56PB801, we can

| Block | Function | Key Components | | :--- | :--- | :--- | | EMI/Standby | Filters AC noise; generates 5V Standby (5VSB) | T3.15A fuse, Viper22A (IC901), Transformer T901 | | Main PFC | Boosts DC bus to 380V-400V | L6562D (IC601), Power MOSFET Q601, D601 | | Main Switcher | Produces 12V, 24V for main board & audio | NCP1200 (IC201), Transformer T201 | | Inverter | Drives CCFL backlight tubes (20+ lamps) | OZ964 (IC701), MOSFETs Q701-Q704, High-voltage transformers |

Critical Safety Note: The Primary side (hot ground) contains lethal voltages up to 400V DC. Capacitors discharge slowly. Always discharge the large 450V capacitor (C605) with a 10k ohm resistor before probing.
