I only replace the old battery with a new one
Try looking for a power fuse and see if its burnt out or if u have another new battery because ive had batteries that were new but really old and they were no good
Hi Joe Spect. Still trouble in your XP80?
Let me tell you: I fixed some Roland´s keys where the problem was as you said, and the battery was perfect. In one case, the problem was a tiny PCB track dissapeared by corrosion. In other cases there was a problem in the battery measuring circut, caused by malfunction of a discret component or a soldering connection loose.
I hope it can help you
It's always possible the new battery had lost it's charge before it was installed. Check it with an ohm meter for it's voltage. Other than that, either the contacts in the battery holder may be in need of cleaning or the battery wasn't installed correctly.
