Service manual WP 895/895F, CP885/885F When the power switch is pushed on, VIN increases slowly. During this time, C806 is charged through R802. As soon as VIN reaches 16V, the STR-F6654 control circuit starts operating. Then, VIN is obtained by smoothing the winding voltage which appears between pin6 and pin7 of the SMPS transformer. As this winding voltage does not increase to the set voltage immediately after the control circuit starts operating, VIN starts dropping.

Service manual WP 895/895F, CP885/885F * power supply functioning during TV set normal run mode - I801 transmits controlled pulses to T801 which generates DC voltages after rectifications by secondary part diodes and electro capacitors (by example by D820 and C813 on 143V supply voltage line). - 8V, 5V, 3.3V supply voltage lines have stabilized voltages obtained by I820, I822, I823 voltage regulators.
