| Where does the 9565BGH get it’s gate from? My continuity check reveals to be connected to only ZD2 and R11. | |

| + | After some more exploring I have found out that the gate is driven by R12 and Q4. When the 9565BGH blew it must have damaged the copper trace between the gate, ZD2 and R11. To make it work again I had to replace the mosfet, ZD2 and the two MBR5200 schottky diodes ( one was short ciruited and I did not want to take any chance with not replacing the second one) and re-trace from R11 to the gate of the mosfet. I have added the circuit from a small part of the reverse enginered circuitboard. Hope this helps someone. |
