I need help

Can someone help me out?

My keyboard is a KN 6000 when I entered the customize menu and hit the button display time out or midi setting load option, the keyboard turns off and restarts. I can you say that I can do, or if instead the keyboard has a defect. Warm regards. Thank you very much.

Re: HELP

Evening

I think you have a hardware failure there. I would also suggest that hitting the keys is just a coincidence rather than the cause of the problem. If it restarts then the 5 and 3.3v power lines are failing. Some of the button presses can be current hungry and enough to stop the machine but it is unlikely.

The power supply circuit you would need to find is on the main logic / voice board and is in two parts, one chopper circuit for the 5volt where the main cap is C355 and for the 3v3 it is C338 both of which are 6.3volt 1000uf capacitors. I would however change them to 16volt 1000uf and ensure they are low esr 105 degree types as these will last the rest of the life of the machine.

This should bring things back to normal.

Let me know how you get on.

Regards

Dave
