N-3626 This is the revised edition of Tech-Info No. 0341. See page 2. Symptom: Occasionally the unit does not boot. At this time, only STOP LED lights. Cause: +5 V has been supplied to U16 (PLL, Main FW PCB Assy) from two different sources. If there is a time difference between them upon booting, U16-14 will not generate the internal clock causing no boot. Solution: Supply +5 V from an identical source (U49-3). This change has been made on the products with S/No. 0080551 and higher.
