Interesting discourse.

Luckily, my engineer friend was able to fix my PSR3000 last night. There was a loose wire.

Now I have to wait for my other one to get out of the repair shop. I might take it out and have my friend repair it as he charges me 1/2 of what the Yamaha authorized repair center charges - with much faster turnaround. He also seems to be more knowledgeable. With both keyboards that the repair shop technician fixed, he attached the Smart Media card drive wrong, and I had to go back for him to fix it. This happened twice!
