I found that if I plug in the sustain pedal BEFORE turning the power on, it works fine. If I plug in the sustain pedal AFTER turning the power on, then it works in the opposite way. Probably just the design. So I would try playing with that before doing anything drastic.

I have same problem. Do you have any solution?

I was bird so I got on my yamaha won"t I c it and it don"t turn on

406-582-5849 if you want to talk about it. I have one here and I'm repairing it. Maybe if yours has part of the upper surface intact I can figure out how to fix mine from yours and fix yours at the same time and test it here

The control may be dirty, lint may have gotten into it. A shot of contact clener into the control while cycling the pedal should clear it up.

I've had the very same problem twice so far. The only solution I figured is to simpy purchase an equivalent key (contact Yamaha service in your country for this) and to replace the broken one. The reason why the key doesn't work smoothly as the other one is not dirt therefore any cleaning won't help. The key is cracked deep in the place where it's attached to its 'axis'. So you'll need to remove all the screws and unmount the cover (it needs a sideshift to open once the screws are removed), be careful with the speaker wires. However you'll need firm moves anyway. Opening is tricky and gets me surprised anytime I do it so you'll need some courage :). Replacing the key is even more tricky. You'll have to remove the broken one by pulling it horizontaly (use some force, it's broken anyway). Placing a new key you'll need to uplift the 'hammer' and then slide a new one. I'm sure you'll figure it out once you see it with your own eyes (it's really hard to decribe but not so hard to do it). Hope you'll do fine. I haven't tried glueing the crack for I doubt it would work for long. Good luck!
