“Yamaha DX7 61-Key Synthesizer Keyboard w/ Case & #3 Cartridge. Internal Battery is at 2.8v
So all the keys work and I went through the presets and all of them worked. The backlight for the display isn’t working. I don’t know how to use the functions. The volume knob works the pitch and the modulation work as well. I think it may need an internal battery but I’m not sure. I’m selling this working for parts or repair due to the light and me not being able to test all the functions properly besides the keys. I don’t want to hide anything but I want you to know that it does play nice and sound good. I took a close up of the chunk that’s out of the back corner. Other than that it’s in fairly nice condition. A little bit of tape residue here and there. The case is solid but the interior padding isn’t super protective so I’m going to add some extra protection when I ship it so it doesn’t move. It will get to you safely. I’m going to wrap the keyboard case and bubble wrap and then put it in a box.” Click here to visit listing on eBay
