“Vintage Yamaha DX7 Synthesizer (not working) the most likely fix is a new battery and a factory re-set, however this is only an educated guess on my part after doing some research. I played it for many years and has been stored in a case and out of dust.The original book is included. I don’t have the tools, knowledge or time to make the repairs myself. – Aaron” Click here to visit listing on eBay
