The contacts can be dirty but most likely they are broken. Contact switches and key contacts are cheap but the labor to replace them is extensive. I would suggest bringing it to a service center if you have not taken apart a keyboard before.

SOURCE: I have a yamaha electone hs4, The foot pedals do not work.

JM: Your problem is this: There are rubber washerson the bolt that holds the pedal on. They are shot. Most likely Yamaha doesnot have the parts.Go to the plumbing dept of a hardware store and get some faucet washers and replace them. YYou can tell if the washers are shot by tiping over the organ and looking at the pivot bolt. Most likely that is yoiur problem. I am an organ tech. and have replaced many of these. DM

When cleaning buttons HOPEFULLY you did NOT use DeOxit or other contact cleaners like Blue Shower as these can damage the buttons that are conductive rubber.

The conductive rubber buttons should ONLY be cleaned with 99% isoprophyl alcohol and Q Tips. Both the conductive "pill" and the traces they contact on the circuit board should be gently cleaned with the Q Tip wetted with the alcohol.

If you used anything but the 99% isoprophyl alcohol, you can TRY cleaning properly and hopefully they will not have permanent damage.

Hi,
You can get the schematic model from your vendor. The model is not available on the internet. See if the electone si still in warranty. If it is call the service centre and get it repaired. I would suggest contacting your country's Yamaha subsidiary or wholesale distributor who may have one in their spare parts department

SOURCE: I have a Yamaha PSR-S700.

You MAY be confusing touch sensitivity with VELOCITY sensing. Touch sensitivity is PRESSURE put on AFTER the note sounds that causes modulation. VELOCITY is what is used for example to control the loudness of pianoo notes depending how fast they are struck. VELOCITY sensing is done by using TWO contacts at every key... one closes first. IF one of these gets dirty, FULL velocity will be sensed and it will be LOUD. The contacts can be cleaned using ONLY 99% isoprophyl alcohol and Qtips after MUCH disassembly of the keyboard. The contacts are conductive rubber pills in silicone rubber domes. Clean boththe contacts and the circuit traces they pres down onto.

Not likely iit is a fuse. The keys are likely scanned as a matrix with two contacts per key. You need to get a maintenance manual for thee organ. Contact Yamaha America parts for music products. They may have the service manual on CD... they used to get $15 for the CD of the manual. Unless you can find something simple like a cable knocked off this could be hard to troubleshoot.
