Maybe Yamaha should ship over a few new systems boards to swap out at this end and then fix the old ones at their leisure "back at base" to put the fixed boards back into new PSR2000? Unless theres been a board change this shouldn't affect the new machines. Machines out of commission for a period of weeks rather than days is not a viable option for most people.

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.

Dear DonM, Bob Gelman and others members,

My PSR 2000 is Main Program 1.10. However it has the main problems DonM claim, solved. So, though I have the possibility to get the upgrade to Main Program 1.20, I am in doubt if I need to make it, as I don´t know any bug 1.20 solve compared with 1.10.
Again I ask the favor to 1.20 owners if they can help to answer to this doubt.

I have seen the main printed circuit board of the 2000.
It is designed to have EPROM and FLASH ROM (both). This is, it could be mounted with EPROMs or FLASH ROMs as there are in in the printed circuit board the places for the two alternatives.
However as all we know, Yamaha decided to mount SMD (Surface Mounted Device) EPROMs. Now the desoldering/soldering problems appear.

I don't know if there is sockets to SMD EPROMs as Bob Gelman suggest, though I guess there is not.

Macallock,

Agreed. That is the way Yamaha should have handled it to begin with. New versions of the KB began showing up in Europe while I still owned mine and it sat in the repair shop for weeks. Yamaha should have either sent one of these to my dealer or sent the internal parts ( entire board if necesssary )to the repair center instead of making me wait for many weeks for a chip that never came. All I wanted as a 2000 that worked the way it was supposed to. I didn't care if it was mine with an updated chip or flash upgrade, or a new one. In subscribing to the "if it ain't broke don't fix it ' theory, my 2000 had other minor quirks, but had it not had the major registration memory problems it did, I would not have sent it out for repair in the first place and chances are I'd still have it. I had already been burned once before when my 740 had a broken pitch wheel. Eleven weeks at the repair center. I feel for Mario. At least in my case, the registration memories failed miserably BEFORE I brought my 2000 to a show, as opposed to during a live performance as was the case with his 2000.
