Yamaha DX7 with E! Grey Matter Project Machine

“vintage yamaha dx7- the keyboard is clean with standard wear. when turned on the screen says ram corrupted. the internal sounds are zero. if turned on holding down #16 & #32 simultaneously the cartridges will play. I’m told the sounds have to be re-installed and the synth is a half step below C. There is a way to tune it but I don’t know a thing about the keyboard. I’m selling it exactly as photographed. No other parts, no cartridges. Consider the synth in ‘not working’ condition. It may be an easy fix for someone who has dealt with these before. I borrowed a couple of cartridges and the instruments sounded great through an amp. I bought it untested about 10 years ago thinking it was in working condition because it looks great, very clean. I thought maybe it needed a battery but youtube instructions looked too complex for a non-repair guy.” Click here to visit listing on eBay
