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.

When you turn a device on it is usual for it to test all lights. The three lights left on is an error code. It could be that one of the keys has got stuck down or that the instrument see it as stuck. There might be debris in the keys. Try shaking out any crumbs. Try vacuuming. Check all controls are in default position. Check noting stuck in any of the ports. The manual may have the error codes listed.

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.
