3) Separate the optical front plate (containing the CCD sensor) from the video board gently while
keeping the board parallel to the optical front plate. Twisting the board set during this step can
bend the CCD pins and will make re-assembly quite difficult ! The CCD chip is mounted within
the optical front plate and should not be removed.
4) After the separation is complete, note the position of pin 1 of the CCD and the corresponding
pin of the socket on the video board. Pin 1 on the CCD is identified by its longer length relative
to the other pins. On the video board, a triangular mark (near the socket) identifies pin 1 of the
socket.
Note: Matching pin 1 of the CCD sensor to pin 1 of the socket on the video board is very
important during the re-assembly process.
