I have a 41C which died about 10 years ago. The battery contacts were totally damaged when the batteries ran out.
Now I powered it by an 6V DC power supply and found that
it's running without any problems after a power on reset.
But once I turned it off it never starts again. With a multimeter I measured a current of 0.33 mA in the ON state
which drops to 0.3 µA when I turn it off. After pressing
ON again the current is 0.33 mA again, but nothing happens
in the display.
Any ideas what's wrong with my 41C ?
