Hello,
I have an Yamaha S90 who not boot anymore. If I turn power on the Display light up, but nothing more.
I have tried with the OS Update to flash the system again, but at Block#2 it freezed.
To give a better understanding I have create a little Video from the Flash-Process.

Can anyone help me to repaire the S90?

Greetings from Germany

Were there any symptoms before this happened?

Perhaps. Let us know if there were earlier symptoms.

Hello 5pinDiN,

I dont know about any earlier symptoms.
The previous owner said that it works fine before this error.
It was only used at home in the livingroom and it looks like so.

Sorry, that you can’t download the video… I can load up to youtube. Is it a solution for you?

The S90 is known to have capacitors fail. This may or may not be related to your current problem:

Unfortunately, no.

Are there any messages on the screen?

No there is nothing in the Display - only light up.
I can start the OS Update Tool with Power on while pressing MASTER, UTIL and STRORE.
But I can not Start the Test Mode with CATOGORY SEARCH, REMOTE CONTROL and MUTE/SOLO.
Do you think it make sense to check the Power-Unit?

If “there is nothing in the Display”, then how did you determine that the updater started?

You could check voltages (as well as for excessive ripple, with an oscilloscope) at the main power supply, and at the various other points as mentioned in the thread I linked to.

While you’re at it, see page 74 of the S90 Service Manual.

Hello!

I also ran up with booting problems.
When starting up the dispay doesn’t go beyond memory reading.

I took my S90 to a Yamaha workshop, the guy tried reading service logs, checked capacitors and even changed one, but couldn’t fix the problem.

He’s advice was to try to get a replacement DM board.
Yamaha doesnt have them anymore.

I need to find a solution ASAP, because my son in using it for piano lessons. Or buy something new.

Cheers, Gregor

Exactly what is displayed on the S90 screen?

The S90 Service Manual diagrams the boot sequence and has procedures to help localize problems when the system freezes. Hopefully the person who attempted to repair the S90 applied that information.

My location is very far from Slovenia, so I can’t help directly. Since time is critical, buying something new might be your best option.

Booting would’t go beyond “ Now checking system memory” screen.

When problem first appeared it stuck one screen further:
“Now checking plug-in board”

When I restarted it, it did’t make it that far anymore.

Funny thing is, I lately had a feeling it needed a bit longer to boot up as before.

Because of urgent situation, I decided and oredered a MOXF8.
Now I don’t have that time pressure to fix S90.

Anybody here has a working DM board to sell ?
