    My understanding was that the polygon mirror motor causes the SC202, but it's the BICU that causes the blank display, hence why both are replaced at the same time. I can't see that a faulty polygon mirror motor would give you the display problem
    A faulty driver IC on the polygon motor PCB can either blow a fuse-resistor on the BICU pcb or just somewhat messing with the BICU power circuit - in both cases - as a side effect - the panel remains dark. From my experience in 4 of 5 cases that little fuse on the BICU is defective.
