you have at risk a schematics diagram of your unit problem? may be the problem is still in the power supply section.
just take note if you flug to ac supply and monitor the present of voltage accross the main
filter capacitor + or - 300v . then unplug watch the voltage across that capacitor if not
directly drain out then the problem is still in primary section of your choper power supply.
