    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. R105, C112 and D105 are the snubber circuit and they function to absorb the spike to protect Q101.
