Detail:
The 2640 rear TFT LCD cover was made with and without LCD Bosses (locator pins). A small number of LCD panels were installed incorrectly on the locator boss covers. This has the potential to cause a horizontal crack across the LCD glass panel. This ECA covers two actions:
1. Preventive Action:
Locator bosses should be removed during any LCD FRU component service action.
Note: All rear cover FRU stock is now made without locator bosses and all FRU stock has been purged of locator boss rear cover FRUs.
2. LCD replacement:
LCD panels can be replaced if they have horizontal cracks and are mounted in rear covers that contain locator bosses.
Locator boss location and removal instructions:
LCD front Cover: TFT Removal.
Note: The Hardware Maintenance Manual dated February 1997 form # S84H-8101-00 contains complete cover removal and replacement instructions.
The complete HMM description is on page 169 of S84H-8101-00. The locator boss identified with a + in the above diagram can be removed with a pair of flush-cut diagonal cutting pliers. The panel can then be reinstalled in the reworked rear cover.
If the rework can not be done, order a new rear cover FRU P/N20H4264.
Notes:
This ECA expiration date is 07/31/1998.
Order all FRU parts locally and record Time and Material to service code 33, ECA 001, and OTHER OFFICE 990.
