Keyboard Troubleshooting

If some of the knobs fail the keyboard self test but some work properly, replace the

rear board of the keyboard assembly.

If none of the knobs work properly, replace the front board of the keyboard assembly.

If any of the keys do not work properly but the LEDs light up, replace the front board

of the keyboard assembly.

If the keys still do not work properly, check the incoming cables.
