My cousin gave me an sx240 he bought in 1984.
It doesn't work.
When I switched on the Kawai, sometimes nothing happens, sometime there's a little bip and then nothing, sometimes randomly some buttons are one, something appear on the lcd screen, but with no meaning.
I opened it and it seems that the battery didn't leak, even though it's 32 years old.
Can it be the battery with no charge? If I manage to remove the battery, the sx240 should work the same, without obviously saving changes made? Or it seems something more serious, maybe something electric or electronic?
Thank you in advance.
Have a nice day.
Sim
