The operation of the keyboard, each button and slider was ok.
There is no problem with liquid crystal display.” Link

“Selling my dad’s old DX7 as a result of it suddenly developing a major fault mid-concert this winter.

The keyboard sadly no longer makes any sound, whatsoever, regardless of output used or amplification source. We have no idea what is the cause of the problem, or the fix, and don’t have the necessity for the keyboard any more to bother to find out.

Up until then the DX7 has worked flawlessly. The keyboard is in overall good clean condition. It has had its fair share of use in the nineties, but has been looked after and kept stored well in its case (soft case included in sale). The keys are not sticky and depress and release evenly and fluidly. The keyboard powers up fine and the LCD display works, although as before would display “grand piano” or descriptions of the sound option selected, now displays random characters as though the memory has been wiped. The cartridge is all there and included.

I do apologise for my poor description- I’m much more a pianist than a keyboardist! If you have any questions please feel free to message me, and I will ask my dad and my aunty to help provide as much info as possible. Considering how much of a cracking keyboard the DX7 is, it’d be a shame not to go to an expert in the field who could restore it to its former glory. ” Link

I really took care of this keyboard, as evidenced by the pictures, and it is in excellent condition both cosmetically and functionally with everything working as it should.

I had the Grey Matter E! board installed shortly after it was released and I also have the original Yamaha DX7 II FD chip that was removed to install the Grey Matter E! board.” Link

s7ii “I’m selling a Yamaha DX7IID in excellent condition. It has a fresh battery installed and plays like a charm.

The Yamaha DX7 synthesizer debuted in 1983 and completely changed the game.

The Yamaha DX7IID is an upgrade from the original “brownie”. It is in a black metal case and has dual timbre capability which means the sounds can be split or layered.

I do not have any voice catridges (RAM or ROM). However, this DX7IID is loaded with 64 sounds and 32 performances. A huge library of sounds can easily be found on the internet.

I highly recommend FM Alive as a utility for getting sounds in and out of the DX7IID and programming as well.

I do not have the original box and packing material. Nope. I can do better. This DX7IID comes with a solid hard case manufactured by Hybrid Cases..” Link

dx7iifd “Here’s a YAMAHA DX7 II-FD. This is a true Classic Vintage Polyphonic Digital Synthesizer straight out of the 1980’s in EXCELLENT cosmetic condition, and perfect working condition. Display is bright, and crisp. Always used and stored in a smoke-free studio environment. My father is the original owner of this synth. He’s an accomplished, successful Motown/Soul/R&B artist, and a complete gear-head. His studio is too cluttered with too much vintage gear that he’s collected throughout his 30+ years in the music business, so I finally convinced him to let some of it go. This item needs no further introduction. If you’re looking at it, you already know what it is. His loss is your gain.” Link

dx7iid “Zu ersteigern gibt es hier einen YAMAHA DX 7 II D Synthesizer, voll funktionsfähig bis auf Audio-Output-Signal, defekt!

Optisch noch guter, aber gebrauchter Zustand, keine groben Blessuren wie Risse, Beulen o.ä., nur normale Gebrauchsspuren durch Gebrauch. Tastatur komplett in Ordnung, alle Taster und Regler funktionieren tadellos.

Das Display hat in der linken unteren Ecke einen kleinen schwarzen Streifen, was aber keine Funktion beeinträchtigt (s. Bild).

Das Gerät geht an und alle Funktionen können abgerufen, bzw. editiert werden, aber es kommt kein Signal aus dem Output, also kein Ton. Die Speicherbatterie ist noch in Ordnung und zeigt keine Fehlermeldung an, und via Midi kann man mit dem DX7 problemlos andere Module, Computer oder Keyboards ansteuern, funktioniert alles wunderbar, sowohl Midi-In als auch Midi-Out.

Wegen des mangelnden Outputsignals verkaufe ich das Gerät ausdrücklich als defekt.

Geliefert wird nur das Gerät, kein weiteres Zubehör.” Link

Keyboard had a new internal battery recently installed as well – looks and plays great! There is a slight clicking sound on the C# key above middle C, but it is completely functional. I am the original owner and the unit has been well cared for; however, due to the age of the instrument (almost 30 years old) it is being sold AS IS. Keyboard will be shipped in hard shell case as a bonus, just needs re-foaming on the inside and it’s good to go. ” Link

2d “Up for sale is a Yamaha DX7IIFD with E! Grey Matter expansion board installed. The synth is in good condition. A couple things to note: The volume slider doesn’t work as it should. When you slide it from down to up the sound goes from off to on at full volume and no in-between. A good cleaning might do the trick. If not, I know where you can buy a replacement. The floppy drive doesn’t consistently work and you may want to replace it if you care to use floppy disks. It’s possible one of those floppy disk emulators could work. It’s just as easy to use midi sysex transfer. Aside from the 2 issues, everything else works and the synth sounds great! Plus, a new battery is installed (with a battery holder so changing it later would be a breeze) and Grey Matter sounds have been loaded! ” Link

dx7iifd “Yamaha DX7 II-FD Digital Programmable Algorithm Synthesizer

Cosmetically this synth is in great condition considering age, minor scuffs to sides, back has some scuffs/scratches, screen/display/keys all in very nice condition.

I purchased this Synth from an estate along with an Ensoniq ASR-10 and DSR1 sequencer (for sale in my other auctions),..I purchased these knowing little about synthesizers.

This DX7 powers up, but I was not able to produce sound, after some research, I found that these synths have an on-board battery, once the battery is dead, all of the internal sound samples get deleted, since this one was said to have came out of a studio many years ago, It is safe to say the on-board battery needs to be replaced. This requires the use of a solder gun, not a hard job. Other than that, I had no way of testing any further. There are no disks or cartridges included.” Link

dx7iifd “Hello! I am selling this classic 80’s synthesizer because I no longer need it. When I had it, it had sounds but now it doesn’t have any. I am not sure if they got erased accidentally. One of the keys is dropped (a black one as shown in the picture) so it would have to be repaired. This model is sold for about 500-600 so I would like to sell it for less than that of course to compensate for the repairs it needs which shouldn’t be major as it was working not so long ago. It could also be the battery since the synthesizer is really old.

Because it is REALLY HEAVY and to prevent damage, I am only offering it for pick up only. It is used so there are no returns. Please feel free to reach me for any questions you may have. Synth is in the Los Angeles area. Thank you! Note: synth sold by itself.” Link
