PSR-S775 stop loading at yamaha logo

[yazarphyo]

Hi guys
My yamaha PSR-S775 stop loading at yamaha logo as per attach file.
I heard that there are some shortcuts keys to go into system files and the keyboard itself can check which error is happening.
But i have no idea which buttons have to be used to reach into system.
Can u guys pls suggest me what should i do and is there anyone who knows about shortcut keys ??
The current is stable and the power supply is normal .

You can try several things:

   
• Make sure no devices are attached, so disconnect all USB drives, pedals, switches etc.
• Try the Test Program. I don't know on PSR-S series, but on a Tyros it works like this: turn the power on with [C#2], [F2] and [G#2] keys pressed and held
• If nothing shows up, try a soft reset. This can probable be done by holding the most right white key while turning the power on. You'll loose some settings, though.

No, holding the most right white key while powering on is a soft reset. You will lose some settings, but not your files.

You're right, I corrected the text.

C#2 , F2 , G#2 also doesn't work

It sounds like maybe it isn't even getting far enough along in the boot process to check whether any keys are being held down and take the desired action (clear the system memory, clear the user flash memory, or run in test mode).

You should take or ship it to a certified Yamaha repair shop and let them look at it.
