Hi Hoxuthi
you could try to reinstall the latest firmware...

Last Year I had a problem with the sx900 that getting stuck on the logo, I could only turn it off.
 I installed its latest firmware and it resumed operation. Try it as a last resort ... and good luck.

Hi hoxuthi,

• I suggest to try first a normal System Reset (already mentioned by tyros5psr): Press and hold the right-most white key (C6) while powering on the S970.


•  If this doesn't help try re-installing the latest firmware first (already mentioned by Aquilauno):
>>> https://uk.yamaha.com/en/support/updates/firm_psr-s970.html

Please refer to the "Firmware Installation Guide" that you can download here:
>>> https://uk.yamaha.com/files/download/other_assets/8/789598/PSR-S970S770A3000_Firmware_Installation_EN.pdf

If you are successful with this method, this has the advantage that your system settings and the content of the user drive are retained.


• If this doesn't help either, i.e. the error still occurs, I recommend trying to perform a Factory Reset using the internal Test Program:

- Download the S770/S970 Service Manual and open the PDF on your computer:
>>> https://psrtutorial.com/lessons/workshops/ServiceManuals.html

- Read pages 38 & 39 of the Service Manual and try to start up the Test Mode. (There are two different methods to do this. So if the method 1 fails, try method 2.)
 
- If the Test Mode can be started successfully, execute Test item "081 : Factory Set", then execute Test item "083 : Test Exit".

- Then restart the S970 and wait unil the "Force Format" procedure is completely finished. If you're lucky, the S970 will start normally again.


Hope this helps!

Best regards,
Chris
