Group code f-e-e2d15i164c-: “laser driver not all lasers red/green/blue write off”

It's most likely that together with this error code another error code is displayed which indicates which laser driver is actually failing. If this is the case see service manual chapter "Location of the main components of the projector", to know the physical location of the specific laser driver.

Situation	Solution
Bad connection between laser driver board, fuse board and LCB.	Check data connection (e.g. reference 1 image and e.g. reference 2 image) between all busbar fuse boards and laser driver boards inside the sealed laser compartment. Check if all data connections (e.g. reference 3 image) between the busbar fuse boards inside the sealed laser compartment. Check data connection, outside the sealed laser compartment, between the busbar fuse board (reference 6 image) and the Laser Control Board (reference 7 image)
