We just inherited a Kurzweil Mark 10 electric piano/keyboard. We brought it home and set it up and it played fine for about 15 minutes. It then shut itself off and we cannot get it to start up again. It is like it was unplugged but of course it was not. What do you suggest we do to get it started again? Any help would be appreciated. Thank You, John Penders

Does anything happen at all when you turn it on or is it completely dead?

The Mark 10 looks like it is brand new and it played for about 15 minutes and then just stopped and went dead. No idea what went wrong.

I have no idea and I'm not familiar with a Mark but can it be as simple as a blowen fuse in the powersupply somewhere.

Is it under warranty? If you do not have the receipt then you might contact Kurzwell service, give them the serial number, ask if it's still covered under warranty.

Mark 10 problem

The consenses was that there is a fuse problem but we cannot find the area where the fuse is. We were told it is near where the cord goes into the machine but we cannot find it. Please help and advise

A fuse holder can be a round object about 1.5 centimeters diameter that unscrews probably counterclockwise likely located on the back of the keyboard. Inside you may find a cylindrical fuse about 6 mm wide 3 cm long. If it is made of glass then you might see the fuse wire inside broken.

Is there not a fuse in the plug itself? Or is that just a UK thing?

The fuses for the Mark 10 are inside the piano right behind where the cord plugs in. To get at it, just unscrew the three screws at the top (from the back). Now you can slide the top (the left on mine slides a bit towards the front, (rotate the top a bit), then slide the right in a bit. Tilt the top towards the back- careful because there are two wires (one each side) for the top speakers. You can see the circuit board with the plug - there are two fuses on the board.

Hope this helps.

I also have a kurzweil mark 10. When I turn it on the lights light up once then nothing. Has anyone ever experienced this. Sometimes it has blinked three times

I have a mark 12 that would not stay powered up. when turned on it would scan and sit at the ready, but press a key and it would restart. you could even sometimes get 1 note. I look at the boards and at the caps on them. on 1 I saw a little bulge. so I went about changing it. I got 5 mins of play before the reset. so I did them all just because. now its working. total cost 54 bucks
