Don,

Bummer! I'll bet that the integrated circuits are surface mounted and soldered in. I spent ten years in the repair business and I wouldn't dream of trying to replace a surface mounter soldered in chip. It would be a disaster. There is a downside to socketed chips that I haven't heard mentioned. They are not as reliable as soldered in.

They should send you a replacement board with the new chips installed. Your dealer could swap this out in less than an hour and you would be on your way. If Yamaha had envisioned the 2000 for professional use maybe they would have done that.

BTW - I'm insulted that you think summer in Michigan only goes from July 3 to July 4. It is only the first of May and it is 50 degrees already. I'll bet by June it might be 60. We only have two seasons here: winter and construction.
