Check if the conductor pattern on the LGC board is short- or open-circuited. Check if the conductor patterns on the PFP board and LGC board are shortor open-circuited. Check if the connector pins are disconnected and the harnesses are opencircuited. Check if the connector CN303 on the LGC board is disconnected. Check if any of the connectors CN241, CN247 and CN248 on the PFP board is disconnected. Check if the connector of the sensor is disconnected. YES Is the tray-up sensor working? (Perform the input check in the test mode: 03-OFF//, //) NO 1. Check if any of the connectors CN241, CN242 and CN244 on the PFP board is disconnected. Check if the connector of the tray-up motor is disconnected.
Check if the power line connector CN502 of the PFP motor is disconnected. Check if the signal line connector CN503 of the PFP motor is disconnected. Remedy: Is the PFP motor working? (Perform the output check in the test mode: 03-109/159) NO 1.Description: PFP motor abnormality: The PFP motor is not rotating normally.Check if the voltage supplied to the CPU input terminal IC24-14 is always “L”? 3. Check if the PLL lock signal CN318-A1 output from the LGC board is always level “L”? 2. Check if the conductor patterns on the main motor board and LGC board are short- or open-circuited.
YES Is the LED on the main motor board lit without flickering? NO 1. Check if the connector pins are disconnected and the harnesses are open-circuited. Check if the connector CN318 on the LGC board is disconnected. Check if the connector CN1 of the main motor is disconnected.
