1. Power Supply (a) The filter network consists of L104, C101, C107, L101, L102, C103 and C104. The main function of this filter circuit is to eliminate the noise that is produced from monitor itself. (b) T101 is an energy converter which transfers the energy from primary winding to secondary load. R104, C112 and D105 are the snubber circuit and they function to absorb the spike to protect Q101. (c) U101 is a pulse width modulation IC which supplies the drive pulse to Q101.

(2) C344 is the Cs capacitor, and Q324 controls C345, Q326 controls C347, Q325 controls C346, Q327 controls C348. The U701 pin 1, 2, 3, 4 controls the Q324, Q326, Q325 and Q327 respectively. So different frequency has different combination to meet the requirement.
