    Be sure to replace booth at the same time. The blank panel is caused by a blown BICU. The BICU is blown because of the polygon motor. If you only replace the BICU, the bad polygon motor will blow the new BICU.

    Cools. Thank you for all advices.
    So replace both BICU and Laser unit at the same time is the key.
