This power supply is for a HP Pavilion Slimline PC.
1 Turn on 330vdc at high voltage cap.
2 No 5vstby or any low voltage rails.
3 PWM chip is UC3845B.
4 PFC chip is 1CE1PCS02.
5 Switcher TNY267.
6 There are 4 optocouplers. PC123. and TL431.
I am retired and a novice at electronics.
Any help would be much appreciated and a schematic would be handy if anyone knows where to get one.
Many thanks in advance, John.
