Roland CR8000 buttons repair made easy

Roland Compurhythm drum machine CR8000 with faulty or worn buttons.

Sounds a lot like the TR808, but a design fault makes these buttons useless after a while.

You will have to pull the plastic covers first, to reveal the spring and rubber dome under which we will drop a bit of conductive paint..

To pull the plastic part you need to push the sides using a screwdriver or two like on this video:

Youtuber The Imp Of The Perverse has made a few vids of his restoration-he used my method too, check them

      1. Ok! Does it seem to last/stay put on the rubber? I’ve seen some comments/reviews by people who have used it for reparing TV remote buttons and claims that it rubs off and creates a short circuit on the PCB (i.e. the button seems to be pressed all the time)

        Perhaps they didn’t let it try properly? I’ve no experience with this kind of paint so that’s why I’m asking 🙂

      2. It worked great for me. Just be careful and do not smear it around-follow my guide-just a drop on the tip! And let it dry for a couple of days. It has worked great for me.. still going strong after all this time.

  1. hello, how did you pull the TOP plastic buttons out ? i cant see it on the video…would be a great help,,,thanx, ned

  2. it saves a lot of work if you don’t have to disassemble the device and solder out all the switches.
    But the way you open the switches doesn’t seem suitable to me, as you can see in the picture above, the side holders are broken.

    1. The machine arrived to me like that. I always assumed they are not broken, they are made like that. But i am always open to suggestions and i am sure there are a few better ways to do this-please show me how you would go about doing this 🙂

  3. the probably “better” but also more complicated way is to open the CR8000, take out the PCB and solder out any defective button, then you can open it carefully by lifting the two brackets slightly on both sides.
    I soldered out all 31 switches and was able to clean the circuit board at the same time.
    i also solved the contact problem with foil, instead of glue i worked with adhesive foil, which seems to work well.

    1. Ok your way is more comparable to restoring the unit-if i had to do that i would have bought new switches and soldered them in. Mine was more a quick and easy repair of what’s there already and non working. At the end of the day no soldering skills were required doing it my way- that may appeal to a few people that are not accustomed to soldering/unsoldering.. different strokes for different folks

    2. Also, my unit had been repaired before using foil.. i cant comment on how long that material can last.. on mine they were not very effective as repair material
