If you';re sure it's the instrument, rather than your amp cutting out or the cord being intermittent, do a factory reset. Beyond doing a reset, it's doubtfull this will be a user servicable problem. You need to contact Kurzweil Support. Here is a link to their page Support Kurzweil

Is this the correct sustain pedal for this unit? It sounds like it should be a momentary button type. I would look into that. Some have a push to work type of switch and some use momentary. If it is, I would open that pedal and clean the switch with contact cleaner, as it appears to be sticking.

It could be your internal battery. Do a search on keyboardforums.com for additional support or Kurzwil website. good luck!

Verify the sound in headphones directly from the unit. The cymbal MAY be panned to one side or the other and will require higher frequency response than some of the piano notes.

That happened to mine. All I did was hard reset it.

It sounds like the new board and firmware has gone to abbreviations instead of fully spelling it out.

I would complain to the store since they should warrant it if it is a problem... but be prepared to accept that the firmware has been changed and displays differently now.

Probably a cable has come loose inside the unit. The keys are scanned by the internal processor as a matrix of two contacts per key. Often the keyboard is divided into two sections.
You will need to have it repaired or if you are electronically adept, open the case and look for obvious problem.

You're correct, that's a power supply problem, but it may also be the power supply connector on the keyboard. If you have access to a voltmeter, check the power supply first.

I would do a factory reset. If this fails then hardware is likely broken and will take forever to be repaired.

Hard reset procedure 1. Turn the Kurzweil off 2. Hold down the KEY START, KEY STOP, and LAYER VOLUME buttons for 5 seconds while powering the unit up, then release 3. Select RUN DIAGS 4. Press the UP arrow until the display reads RAM TEST 5. Press the START/STOP button to run the test 6. When the display reads SUCCESS, turn the unit off and back on. The unit is now reset. If your Kurzweil still does not come up to the normal screen after this procedure, it will require service.
