Well folks, I found the problem. I finally figured out how to take the rubber key pads off for examination; and sure enough, one of them was ripped as if had been cut by a knife. Don't understand how something like this could happen, unless something fell on top of the key and hit it quite hard; it's something I consider almost impossible to do by just "playing" normally. (Donny, I know you are a “hard hitter” but even you couldn’t have done it on our last session)
Any way, the KB has a total of 4 sections of rubber pads plus one single pad for the top key. The repair is a rather simple one, since all I need is to replace the damaged pad section. Which I'll be ordering from yamaha in the morning.
Taking the structure around the pads to get access to them is a little tricky, unless you know how the whole thing is put together, which took me a while to figure out. Essentially, the pads are "sandwiched" in place by two solid-state circuit boards, which simply snap in place held by plastic push lock tabs, not screws.
I switched the rubber pads in the keyboard by placing the bad one (which was in the lower section) at the high end of the KB or the highest octave, which I can do without until I get the replacement pad section.
I am excited that I won't have to send the keyboard out for repair and get laid up for a month by fixing it myself and, that I will be able to perform on Saturday night.
I hope this can help someone who might run into the same predicament in the future.
Are you listening Scott? It’s just a matter of time buddy!
Yes, this keyboard was built as if Yamaha was already losing money on it. Lets hope the Tyros isn't built with the same philosophy of the psr2000, you know folks, catering to the "home players market"
