The FSP212-3F01 psu originally came in dead as a doe doe! Replaced all the secondary caps, q7, zd4, r65 which gave me a good 5V standby but no inverter voltage and no 12V.
Then changed the L6598 ic1 which has given me 20V and 10v when the tv is switched on. The voltages should be 24V and 12V and not 20V and 10V so wondering if its going to be the optoisolator that is causing the drop in the feedback circuit? As the outputs are 17% down!
Any thoughts on a solution?
