Hi all, I've just acquired a Roland U20 keyboard and when I powered it up it showed Grand piano,the keys all worked,I tried the Romplay demo, they worked and I thought Great, I've got a bargain. When I next powered it up a few hours later instead of the display showing Grand piano it showed some strange characters(crochets and things) and the keyboard plays nothing.The Romplay still works but no keys.Could it need a new battery,if I replace it will I need to load factory reset data and if so where can I get it and how do I do it? Or has it just given up the ghost.
Any help gratefully accepted as I don't really want to scrap a nice keyboard.
Regards Colin
