SYMPTOM
No display on the operation panel LCD, some characters on the LCD are displayed
garbled, or the power LED does not light when the main switch is turned on.
CAUSE
Some controller boxes were attached on the production line slightly higher than their
optimal position, resulting in poor connection between the controller board and BCU board
connectors.
SOLUTION
Temporary (from mid-October 2003 production):
The screws for the controller box are secured while the controller box is held in the proper
position.
Permanent (from November 2003 production):
The height of the application middle bracket has been reduced by 0.6 mm to ensure the
controller is always attached in the optimal position.
