I have a Roland Juno-D that I've kept in storage but recently brought out to play again. But some of the keys don't play. Through hours of searching the Internet, I have found that I have to clean the rubber contact strips with 99% isopropyl alcohol. Well my issue is how do I get to the strips? I opened the bottom but see no way to get access to the contact strips. It seems that all the circuitry is blocking it. Thank you in advance for the help.
In order to access the contact strips, first the keyboard needs to be pulled out of the Juno. It is held in place by twelve screws going through the sliver mounting plates along the back edge of the keyboard, as well as two screws on either side of the keyboard. Once the keyboard is out, you need to remove the keys which are covering the contact strips. Use a pair of pliers to pull the spring off of the back of the key. Then you can lift the back of the key up slightly and move the key forward to remove it.The contact strips will now be visible. You will notice each key has two contacts, one is a little lower than the other. When you remove a contact strip, take note of which side the lower contact was. When you put it back it needs to go back the same way or velocity sensing will not work . Also, be careful when pulling the contact strips up. If you are too rough you could rip a contact strip.Cleaning does not always solve dead key problems. Sometimes the contacts are just too worn out. In that case the contact strips need to be replaced, or re-coated with a contact repair kit, like this conductive paint, or these stick-on discs.MusicTech1441063.620340162
Hello again. I came across this video which I believe shows the procedure better than I have explained it.
Yeah, I found that video earlier. Thank you though. I've tried cleaning the contacts but it didn't work, so I ordered the conductive paint. Thank you very much for the assistence
