My tech found the problem with an electronic part that was too small to replace so he changed the hole jack board and it took almost 3 months to get the parts. Works fine now, but I had to buy a whole new keytar in the meantime. Gigging without it made me settle for the only one I could get my hands on and it’s a black one. I was skeptical but it’s so sexy and I’m in total love now. Now the repaired white one is reliable a backup.
Hello. Sorry it took me 2 years to answer your question. I was having exactly the same problem with my AX-Edge(white) which was just out of the warranty period(Murphy's Law). I need to say Roland's customer service is not the greatest or the fastest. I found a local service center through Sweetwater Music Center(great service) but before taking the units there, avoiding a service charge, I decided to open the unit and inspect it visually to see if there was a replaceable coin battery. The process was very easy. Just put the unit facing dawn on a soft bed and take the screws one by one into a cardboard in the same position to ensure you put them back in the same order. They are many screws, all the same width but there are different lengths. To my surprise I could not found a replaceable battery! Yep, no coin battery to replace. Instead I carefully disconnect and reconnect all the multipin connectors I could find in the main board and then reassemble the unit. And Voilá!! Its working perfectly now. The only tool I needed was a Phillips #2(common standard) screwdriver. I took me about 5 to 10 minutes. I really hope this publication can help any other colleagues out there. Please keep making music, it can make the world a better place. Rock & Roll!!!
