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.

You may not have the patience level to attack it. Few ppeople do.
