MAIN board, INPUT board and RGB board
Note that the MAIN board is attached to the I/O metal with the
INPUT board and the RGB boar. They all are removed from the
projector together. (See the picture on the right.)
When you detach this block from the projector, lift the side of the
MAIN board while sliding it as shown in the picture so that the
INPUT board cannot be caught by the optical unit.
PWB assembly MAIN
Attach the MAIN board in reverse way of the disassembly procedure above so that the INPUT
board cannot be caught by the optical unit when assembling the projector.
I/O cover
When you attach the I/O cover, insert its claws to the slits of I/O metal as shown by black arrows
in the picture, and lock it. It makes this work easy to insert two claws on the lower side fi rst.
Confi rm that two bosses of the I/O cover are fi xed in each holes of I/O metal as shown by white
arrows in the picture. Make sure that the I/O cover is contact with the I/O metal tightly.
