Hi all, I have just acquired a U20 and when I first powered it up all seemed OK. All keys played,display showed Grandpiano.I then selected RomPlay and both tunes played OK so I turned it off and congratulated myself on an absolute bargain. When I powered it up again instead of Grandpiano on the display I got some musical notes(quavers etc) and general rubbish, non of the keys play anything but the Romplay still works OK. I've read it could be the battery but if I change it will I have to Factory Reset it. If so where can I can a factory reset rom and how do I do it? I have a working U220,can this be used in some way. Sorry if this message appears twice but when I first sent it nothing appeared on the group(the same happened with the last post I sent) so I've had to post again. Any help gratefully accepted,It would be a shame to split it up for spares.
Regards Colin
