Hi,
I am troubleshooting a Panasonic PT-AE4000U power supply. I tried testing the MOSFET K3561 with my DMM in diode setting and the mosfet didn't turn on. I order a new 2sk3561 and it would not turn on either. I tried three different DMM's. What is going on? Do my DMM's not have enought voltage to turn on the K3561 or what?
I have an old Heathkit IT-121 transistor tester that will test FET semiconductors. Do you think that will test MOSFETs?
Any help would be greatly appreciated.
