Hi,
i've got my hands on a HP16702A Logic Analyzer. Unfortunately, a few seconds after power on the Power supply died. It looks like there's a small standby power supply in these units. An unknown TO220 Mosfet(?) bursted, so i can't read any part number anymore. I've attached a Picture of the PCB with the missing part. Does anyone know, what this part is?
What is strange is that Pin 2 connects to GND, and Pin 3 connects to the small standby transformer. I would have expected it the other way round.
