Having just completed the KIO2 module, I discovered that the onboard oscillator doesn't. I've isolated it, had it apart twice, checked all components and pcb lands, replaced the FET even though my analyser said it was OK. The FET is running very hot, perhaps 50 deg C. If I inject the required negative voltage into pin 8 of the IC, all voltages come up correct on the pins, so it doesn't seem to be anything to do with that. I'm just about to knock up a crystal checker, but while I do, has anyone else had this problem?
