Yamaha DX7iiFD issues

Postby ajloeff15 » Sat Aug 19, 2017 4:58 am

Hello,

I have recently purchased a DX7iiFD and am in the process of getting it back to working order. The synth powers on, but doesn't respond to any button presses. It also doesn't send any midi data. I have checked the battery, as it seems that is a common issue, but it reads 2.7V with a meter. I'm wondering where to go from here. I have attached a picture of what happens with the screen and numeric displays when it powers on.

Thank you!
