Report "Opti 650es. Not working at all, blown bridge (BD201), also C204, not sure of pin out of the transistor K2608, (Q201), have removed from cicuit and tested using transistor test, only measuring 0.478 between 2 pins other pin appears open ciruit. Have concerns about the transformer (T201), only measuring 1 ohm between the leg going to R203 and the one going to R212. The surge actually blew out a leg of C204 and left a burn mark around the pad holding the heatsink attached to Q201. The transistor is completely isolated from the heatsink. Any help would be grateful regards John"
