RolandXP-50 mainboard repair

I have a roland xp-50 . everything works great ie display, dial, all buttons etc. I lost sound and replaced the backup battery. I did a factory reset. Still no fix. I ran the internal test program and in memory test everything checks ok. But where it says battery (which should read around 3.0 volts) it reads 0.0 volts. Has anyone else run into this issue? If so please help! I love my Roland!!!
