Features a bridge rectifier configuration (often using RL207 diodes) and a main filter capacitor where high voltage ( positive 400 cap V or standard tilde 310 cap V depending on PFC) is present. Oscillator IC & MOSFET: Typically uses a (U1) as the PWM controller and a (U2) for the LED driver. Voltage Rails: Common outputs include , and specific supply lines for the LED backlight. Note that there are over 200 variants of this board. You must match the barcode number Oscillator IC & MOSFET: Typically uses a (U1)
