Same problem here with a PC-1403

Thanks for the tip.

Funny thing is machine is unresponsive to ON/OFF switch position. Remains BUSY even if tab in OFF position. Reset buttom does not help. Switches off when Reset pressed, but return to BUSY when Reset released. No obvious corrosion/dirt on board.

Anyway, a nice looking machine. I do not think I would make much use of it, even if it worked.

edit: vendor claimed issue arised after a battery replacement. Perharps pressure on board during replacement set lose the chip ?

good luck, Dave. If you are lucky, maybe I will
