Hi, I am repairing the power supply of my video projector and I need to
understand what type of diode is mounted here, in the green circle:
http://tinypic.com/r/2ltiwko/6
I see that it have three colored rings, but if I decode it with resistor
color code I obtain 652, that don't tell me nothing...
because the red ring is more width than others, I suppose that the
reading is 6522, but I don't find SMD diodes with this coding...
this diode is connected between gate and source of power mosfet, that
its source is connected to ground through 1.2ohm resistor.
this is a zener diode or schottky diode? :-(
thanks for your aid
1N4256 ?
Can you identify the exploded 8pin driver?
Are the 4 pin devices ,over the isolation slot, opto couplers ?
Do you know the failure initiation/progression?
