Thanks a lot! You just helped me fix the dead keys on my 30 year old D50. I was 17 years old when I bought this synth. I have been using it ever since. I am glad I found this video and the courage to repair it myself. Hail from the Netherlands!

All I can say is AMAZING!!!!! I own a Roland JV1000. I hadn't played it in years because of the dreaded red glob ooze. When I took it out, my initial intention was to address that. I marked the keys that were still stuck from a prior attempt to "unstick" them .. I was very meticulous and methodical. I found that there was a thin plastic strip which prevented the keys from sliding out. I stripped that off and then went to work on all the stuck keys. Fixed them and put the synth back together and to my surprise had about 10 dead keys and some that were striking full on.. I was so irritated. I looked at the contact boards and there appeared to be some glue residue, cleaned the boards and still had dead notes. I scoured the Internet and found used replacement contact boards for a JV80 which would have fit the JV1000 but I did one more search and found this here. I gently cleaned the tips of the rubber contact strips and used the "graphite" fix for all of the contacts on the contact board, turn it on and every key played flawlessly. Thank you .. Thank you .. Thank you!!

A really nice video for us happy People playing a Roland D-50 😀

Hi Tom. This video helped so much. I fixed my dead note on middle C using your video. Thanks Avesh from South Africa 🇿🇦

I have just fixed a dead note problem on an old S50. I have little electronics knowledge but followed a number of videos. The keys were, from the bottom, Csharp A above and F above that. Tried all the cleaning tips on these videos and no joy. Tested the diodes and continuity of circuit traces with a multimeter - all diodes were OK but there was a break in continuity on one trace beween the bottom and adjacent keyboard circuit boards. The problem was a pinhead size spot of corrosion on one copper trace. Cleaned back and fixed using silver conductive paint - voila - notes restored. These videos are a great source of info.

Thank you so much for this video. I bought a D50 last week and one of the keys dropped and stayed like that. I figured it was probably a spring or something. I am so happy to have learned how to fix it myself with your help showing how to remove the keybed. A very enjoyable experience.

I've spent half an hour trying to get the bottom back on but you've just clipped it in. :')

Many thanks, your tutorial was really helpful ! From Brussels with love.

Worked like a charm! For my D20. I thought it was gone forever. Thanks so much!

Great video! Very thorough, all bases covered! My only comments would be that I admire your confidence that the problem(s) was fixed before you replaced ALL the base retention screws! I always test the repair(s) before putting all cover screws back in. Next, I highly recommend magnetizing all my screwdrivers, manual and powered, to keep extracted screws from falling into whatever I'm working on. I use a salvaged hard drive magnet to quickly magnetize the shafts. Screw replacement is also much easier with screws which stick to the driver bits.

Thank you! I have a few dead keys grouped together on my Roland and am going to try this. I would love to get it working again.

Cheers Tommy Thanks for this needed to change a broken Key , Followed u and now works great, Difference was wires also tied with plastic ties to keyboard as well as screws, Advice to anyone be careful very hard to cut without cutting wires so make sure you put a small screwdriver between wires and blade when cutting, you can cut one tie then pull keyboard out slightly and cut from bottom.

Cool, nice video, thanks. I had the same problem on my D50. Just 2 points :

Awesome! This actually helped me with my Roland D20! Thanks! :)

This is why men rock. Thank you so so much.

If you haven’t, try patch base- I can import/export entire D50 libraries at the touch of my iPad, I can also control every parameter in real time. All patches get backed up to the cloud. It’s incredible.

Thank you for sharing this video. I had 1 dead key that wasn't working, and wondering how to get to it and clean it. This really helps.

Thanks a lot for posting this. I had two keys on my D20 that always sounded at maximum velocity, I fixed them today.

Tommy, thank you for doing this video! I'm going to attempt to fix a couple dead and nearly-dead keys on my old D-50 before I do the unthinkable....trade it in!

Ok thank You very much.
