Remedy: 1. Check the connection between RX motor and the Connect A PCB (P90). (See page 2-1.) 2. Verify the RX motor rotates when the power is on. If OK, see step 6. 3. Check the power is supplied to the Rx motor. If it does not, see step 5. 4. Replace the RX motor if it doesn’t rotate. 5. Replace the Connect A PCB. 6. If the problem is not correct, replace the main control board.
Code: 02

Code: 06
Description: LCD Failure
Remedy: 1. Verify that the power cord is correctly connected and the power switch is ON. 2. Check for a blown fuse or open circuit on the unit’s internal power supply. 3. Check the DC output voltages from the power supply unit to connector P3 on the main control PCB. If any of the following voltages are incorrect, replace the power supply. • Pin 4, 5 : +5 V • Pin 8, 9 : +3.3 V • Pin 6, 7, 10, 11, 14, 15 : GND 4. Check the following connectors: • LCD assembly to the Panel PCB (P52) • Panel PCB (P50) to the Harness to the main control PCB (P5) 5. Replace the associated PCBs and connector harness.
