Hi,

I hope someone might be able to help.

An issue has just arisen with my daughter's keyboard, it's worked with no problems for the 2 years we've had it, but now it keeps freezing after we turn it on.

When it powers up it will work, all keys, all buttons, for anywhere between 1 - 10 seconds before freezing and showing just "ROLAND KR-500 DIGITAL KEYBOARD" on the display.

It will then not operate at all, no buttons, no keys.

I find the factory reset buttons, pressing from and to and then write, which shows on the display as being reset, but it hasn't fixed the problem of it freezing.

Any help would be greatly appreciated.

If DIY is what you mean, I would start by opening it and disconnecting and reconnecting the power supply to mainboard(ish) cable to check ir some bad contact is occurring. Also take a look at power supply's electrolytic capacitors and see if they are not bulged, what indicates they are deffective. Also check for leaks around the same capacitors. If no leaks, bulges and no bad contact, try the same with other cables. These would be my first troubleshooting steps.

Yes, EVC2017 has got it... unplug it, turn the power switch on and off a few times... then let it set overnight. This will allow most of the juice in the capacitors to dissipate and you should get a fresh reboot. If this does not work, Roland has a pretty darn good help line. I have used it and they are pretty good.... although they may just give you a local authorized repair shop.

Oh... and disconnect anything you have plugged into it such as headphones etc.....
