Table 7.1: 35/70 Fuse Block Identification
The corrective procedures in the checklist allow for recalibration of various electronic cards. This should be necessary
only in cases where cards have been replaced or unnecessary adjustments have previously been made. All electrical
adjustments are factory-set; additional adjustment should not be required, especially on a projector that has been
operating.
This troubleshooting procedure goes only to the card level. Defective cards should be returned to
