My S90XS is around 5 years old and has worked flawlessly until now.  When I turn it on, the screen doesn’t go through its normal boot up, ending with the “Lay It Down” screen.  Instead, it displays a message that says “Searching for firmware updater”.  After a few seconds another message appears, which says “USB memory not found”.  As far as I know, I have done nothing to initiate this.  It just happened about a week ago when I turned the keyboard on.  In this mode, the keyboard will not accept input from any button (except to make it cycle through the same messages), and of course it does not play.  I have tried turning it off and back on, removing the power cord and plugging it back in, and tried to do a factory reset but, as I said, pushing any button has no effect.  I looked through the forum and tried searching but didn’t find anything on this problem.  Does anyone have any idea what is wrong?  I’d like to try anything you may suggest before spending a lot of cash.

Thanks,
Steve

Welcome to the forum.

Under normal circumstances, the S90 XS firmware can be updated by simultaneously pressing the [ ^ ](Cursor Up) and [UTILITY] buttons while powering on the S90 XS. At the time, the firmware would be on a USB flash drive inserted in the TO DEVICE port at the back of the S90 XS. If those buttons were pressed without a USB drive inserted, the error messages you’re seeing would be displayed.

I presume you’re not pressing those buttons - but your S90 XS “thinks” you are. One way that can happen is if something was spilled on the front panel, and there’s now a conductive path at the relevant switch contacts.

Any possibility there was an “accident” with a liquid?

Well, if there was, I don’t know about it.  We do have grandkids though so anything is possible.  What you say certainly makes sense; it seems the “key” to the problem is what made it go into this mode to begin with. I guess I need to open it up and see if it looks like there’s anything there.  What I’m afraid of is that it came from some kind of component failure and I’m going to have to buy a new board of some kind.  I expect that would be pretty big money.  I put in an email to Yamaha support and they sent me the names of a couple of local companies that might be able to work on it.  I already contacted one of them and got no response so I’m not too encouraged about taking that route.  Thanks very much for your comments.

And thanks for the welcome!

I’m not sure how obvious it will be to get to the top side of the control board where the switches are, and any possible spilled liquid might have found its way. I’d suggest first obtaining the service manual from Yamaha if you intend to investigate this yourself.

By the way, sometimes the problem isn’t obvious. I’ve seen spills which dry and everything seems normal until the humidity gets high, and residue becomes sufficiently conductive.

Of course, there might be some other cause of the symptom, but in my experience it’s worth checking for signs of a spill before considering something worse.

Best of luck.
