Yamaha DX7

“Vintage Yamaha DX7 DX 7 digital programmable algorithm synthesizer for parts or repair. Powers on, display shows 88 and top row of LCD is solid black boxes. I’m a guitar player so not real familiar with these. Bought it sight unseen hoping it worked but not so much. From what I could find online, possible issue is dead battery. Opened it up and confirmed battery is good at 3v. My troubleshooting abilities and interest stopped there.” Click here to search for synths on eBay
