Hi Bill

 I do not recommend erasing the EEP-ROM.
 All maintenance information is erased and has a negative effect.

 I would advise you to check following points.

If you can remove the keyboard lid, check the  sensor connector ( around 88C key)
reconnect the D-sub control cable.

Test mode--- Error history display ---Error message.

Maintenance mode ---Test play ----pp,---- Key No, and Velocity(V,v)
