I hope for your sake it is on a service contract, cause you need a trained tech. The following is just a glimpse of the service manual (which is not able to be posted here)
116-323 Switch the power Off, then On. If the problem still exists, perform the following: CAUTION Switch the power Off and observe correct ESD procedures when removing and re-installing items from the ESS PWB. • Remove/insert NV-RAM Board and power ON. . • If 116-323 problem persists, replace NV-RAM Board. • After replacement of NV-RAM Board , 116-334 may occur. Take the action for 116-334.
