“Amazing mint condition D50. Comes with manual, memory card , video tutorial , and sound charts.
Unit is mint condition but remember it is a 1980’s keyboard. Sounds amazing by the way.

Purchased a year ago from the original owner to use on a production, But it arrived to late and therefore we never actually used the item.
Original owner said he had it from new and never used it , so it has little to no use as seen in pictures and has all the accessories you see in the pics.”

“Powers on, but gives a ‘check internal battery’ error. I’ve tried replacing the battery several times, but no success. It doesn’t retain any sounds in internal memory. Also, the 4 buttons (Upper/Lower/Value/Local) next to the X/Y joystick don’t work.

It is possible to load and play patches one at a time into RAM via SYSEX or MIDI and the Roland D-50 Librarian software on a PC (see picture 8), so the keyboard does work. All the keys work and respond to velocity, and the rest of the front panel functions, including the bender and after-touch.
It sounds lovely with a low noise floor and all outputs seem to be functioning correctly as well as MIDI in/out/thru. I haven’t tested it with a memory card as I don’t own any to test with.

I tried to fix the problems myself by replacing several capacitors, diodes and chips on the main board, having taken advice from an engineer, but to no avail. My soldering is not neat but the replaced components appear to work correctly.

The exterior of the keyboard has various scratches and scuffs, some of the keys have chips/marks, all consistent with age. (See pictures)

Given the above problems I am selling the keyboard strictly for SPARES OR REPAIR, although I recommend repair to be attempted only by a professional electronic musical equipment repair technician. I will not consider selling individual components separately. This auction is for the whole keyboard. No power cable included, but uses a standard IEC kettle lead. UK Voltage 220V-240V.” Click here to search for synths on eBay

“This keyboard is in good condition for its age. It’s recently (6 months ago) had a new memory battery fitted, and has all its original patches.” Click here to search for synths on eBay

“Works perfectly, has very minor cosmetic issues at all. Sounds great and comes with power cable. The pitch bender seemed to stop working, but I will attempt to fix that before shipping.

I only used it through a mono output and it had a minor scratchy sound to it but it may be just some part of the patches/configurations.”

” This was a project I picked up with the hope of fixing but it’s now sat on my desk for a few months without me touching it leading me to realize I won’t have the time. It does start up but there are lines over most of the LCD screen. In testing when you push certain buttons the display does change (see pictures). Plugging it into my board I wasn’t able to get any sound out of it. Last, but not least, the person I got it from lost all the screws keeping the back metal panel secured to the frame, so you’ll need new screws. My lack of time can be your gain.”

“Selling my Roland D50 for Parts or Repair. I have tried to get this thing going, but I must be missing something.

The power supply has been rebuild to be the Caps were out of spec and some voltages were off. Also the key contacts have been clean. I have changed out the back up battery as well.

As you can see in the photos when the unit is powered on it loads and goes to what looks like the patch screen but it is call scrambled up. I have read on like were people reload the factory patches from a card, but I do not have any D50 cards.

Most of the panel buttons work, but they will all need to be cleaned. And you can see it is missing one key from the photo.” Click here to search for synths on eBay
