the warranty has expired. The power supply has been checked and is ok. Suspicions about the built-in CMOS NAND memory. To check this you need a dump from the working tool. Then it will be possible to write it to a new memory.

Hello! The instrument froze during performance. After resetting the power and turning it on, the download stops and does not reach the end, all buttons are inactive. You can turn it off only by unplugging the power supply from the outlet. The piano can no longer boot. What could be the reason?
