A friend brought me the control panel from his washing machine, made by the now defunkt ISE.
A switching IC in the power supply has "let out the smoke", unfortunately the top of the IC has blown off (and cannot be found) so we are left trying to identify it.
It's an 8-pin DIL device. Pins 1, 2, 7 & 8 are ground/heatsink, pin 5 is connected to the switching transformer and 3 & 4 are connected to a couple of feedback? resistors and the on-standby toggle switch.
I've removed the chip and there is noting on the underside to identify it.
Any help/hints gratefully received, TIA.
