Psr s 910 keyboard. Why does it turn on for 5 minutes, then turn off?

Be sure to use the original adapter and still in good condition/normal.
Have you tried, at the time after 5 minutes then turn off, and then you restart immediately, the unit is turn ON again? Or is there a time lag to ON, after power-switch is pressed?
Errors like this one,may be due to defective adapters (works only for a moment, after being hot, stop sending voltage), and can also be caused by damage to the regulator section in PSR910.
To check this, it must open/disassemble the PSR910.
