Rubber Pads In A Musical Keyboard Replaced and Maintained. Model: KORG-B2
A guy from Jerusalem area about 30 minutes away brought this musical key board for repair.
That is an expensive musical key board and the main problem is some of the keys on it not active (no sound when the key is hit).
If you look closely to the keys marked with green stickers; these are the keys that not active and from checking on line
about this problem it has to do with cleaning unless the key rubber pads are worn out and need replacement.
The keys are divided into sections. On every section there are two screws holding it down to the base. Took these screws out; there are two plastic clips on the back and once they are unclipped, the keys will come out nicely.
So the keys were out and the rubber key pads are exposed. As seen in the photo, it was really dusty. I cleaned all the pads and the boards but sad to say the keyboard was not repaired. I checked almost everywhere about these pads; they are hard to be found and if they are found, they are expensive to buy. I called the customer about the situation so he came and got his unfixable keyboard back.
Later that night I was checking online and surprisingly, I found the same exact pads on Ali Express for a cheap price. I called the customer and told him what I found. I sent him the link and he ordered them online.
About two weeks later the customer showed up to my shop with these new rubber pads and the keyboard. I replaced all the pads; when I was done the sound was restored in all keys and the customer was jumping with joy to the sound of the key board that was playing music in my shop.
The customer paid me very generously and thanked me for not giving up on this repair. The customer’s son was joyful and his smile was wide on his face. I was pleased with the outcome and happy it worked out just fine.
