“YAMAHA SY77 Synthesizer – USED but the built-in battery and the LCD backlight were replaced!! All keys have been checked and pronounced. The LCD backlight and the built-in memory battery were replaced. Bends and modulation are good. The FDD has not been tested, but it is possible to save tone data to PC via MIDI in bulk, so there was no particular inconvenience. Overall, the product is in good condition and shape though, it has some normal wear and tear. Please check the item images and the description carefully.”

“Yamaha sy77 SY-77 FM Synth Workstation – Vintage.

A great FM synth that sounds amazing.

It is in used condition with marks all around and some of the usual breaks to the casing at the back corners which is often seen on these.

There is some sticky residue on the back of the synth where someone has put tape on for some daft reason.

The print on the face is all still intact and clear.

The buttons mostly all work with the exception of one or two sticky buttons on the right hand section where you choose the patches but they still work with a few presses.

These buttons can be replaced quite cheaply, but as the board is deep in the synth it’s a bit of a long job to do, I have done this on another one I own and the actual soldering was easy enough as the circuit boards are old decent quality, but as the button mostly works anyway it would only be a job I’d personally do if I was replacing something else at the same time like the LCD panel.

I’m not sure if the floppy drive is still operational as I have no way of testing it. These can easily be replaced with a usb unit which offers a far superior experience. I have replace this in another one I own. These is info on Google, YouTube and eBay about this.

The keybed is all intact and nice and white, they quite often go yellow. I think there is maybe one sticky black key in the middle somewhere.

I’m not sure if the back up battery has been replaced but it still holds memory as it should.

The LCD screen backlight maybe gone as happens on these but you can still see what’s going on. These can be replaced with good modern led units or fixed using el panels, look of YouTube and eBay for info on this. I have done this with another one I own but it’s a bit of a long job as it is located deep within the synth under several circuit boards.” Click here to visit listing on eBay

” Yamaha SY77 Vintage Keyboard Synthesizer – NOT WORKING.

Please read the description carefully. I am not the original owner so I don’t know what’s broken or if it can be fixed. A couple weeks ago I bought this from another seller on here who listed it as “tested & working”. When it arrived it clearly didn’t. I then looked at the photos again and realized it wasn’t even the same SY77. I asked the seller if they had perhaps sent the wrong item by mistake, they gave me a full refund but offered no explanation. (You however will receive the exact item pictured, as shown by the serial number printed on the back). To corroborate my story I’ve posted my purchase and refund in the last two pictures, but if you have any doubts about this item, please do not buy.

The synth turns on, but the screen is completely blank. I know the screen is getting power because the contrast knob works, but nothing appears and there is no sound. I checked the power supply and verified all secondary voltages (+5v, -5v, +12v, -12v) work properly. I believe the floppy drive is dead because when I turned it on the red light kept blinking, so I disconnected it from the board. The screen backlight is also dead (a common problem with these) so I disconnected the backlight inverter too. Made no difference, the screen is still blank. The back is missing a few screws.

On the plus side, overall cosmetic condition is very good other than a few scratches. All of the keys appear to be in good condition, but since the sound doesn’t work I don’t have a way to test them. I opened it up and the boards look good, nothing is obviously missing. Previous owner soldered in a new battery, I tested it at 2.5v, so most likely someone has worked on this in the last few years. It may be possible to fix this synth or use it as a source of parts, but it’s beyond my abilities so I’m selling it. Feel free to ask additional questions or for more pictures.” Click here to visit listing on eBay

“I’ve had this monster since 1994 – overall good condition, a few scratches on the end panel, right hand side, a couple of minor scratches across 1 black key, some wear on the case paint under the keyboard – see photos. Home use only.

All button lettering is still visible, backlit LCD display in good working order & fully legible, all buttons and controls working, all audio totally clear and fine, MIDI all good, all keys working with velocity & aftertouch. The floppy disk drive spins but no longer reads data – this will require a replacement belt, and is a common age-related defect.

It still sounds *amazing*. Combine the FM synthesis engine of the DX7II with sampled AWM waveforms, pipe it through the powerful resonant filter, express yourself with the 2 mod-wheels and aftertouch, and complete the experience with the onboard effects.”

“Excellent Vintage Yamaha SY77 Music Synthesizer Made in Japan Works great. Condition is “Used”. Local pickup only.

I have no way of testing the floppy drive or Midi outputs and inputs. But it turns on, I can switch patches, and make sound through the headphone input. One little problem is that the D# an octave above middle C gets stuck. It makes sound, but it gets stuck so you have to lift it up to make it stop playing. I’m sure this just needs some cleaning and tlc. Otherwise everything works great.”

“I installed a gorgeous new black and white screen, a long and laborious task that is worth paying someone else to complete. Because the new screen is installed, there is no annoying converter whine. The keybed is fantastic, and there are no issues with it – the keys all work, the aftertouch feels great, and the velocity works perfectly. I’ve experienced no jitter/noise with any of the faders or the jog wheel. Comes with original Yamaha sustain pedal, as well as the SAX 1 and DRUMS 1 wave and voice cards. The onboard sequencer is very similar to Yamaha’s QY line (think Squarepusher), and integrates very well with the internal RCM synthesis engine.” Click here to visit listing on eBay
