For the FULL
SPECTRUM MOD only, you will need to do some extra work to adjust
the CMOS Imaging Chip Assembly by re-shimming its position so
that the camera's Auto Focus function will operate correctly.
If you do not need the camera's Auto Focus function to operate
correctly, you can skip this procedure. CLICK HERE for re-shimming procedure.
35. Blow out any dust from the camera body
cavity with a blowers bulb. The filter/CMOS assembly will now
be placed back into the camera body. Notice the three focus shim
locations in the photo below. There are black pins holding the
shims in place and each shim has a hole for a mounting screw.
Line up the three holes in the filter/CMOS assembly frame with
the three pins and place onto camera body. Start by inserting
the upper left corner, then lower left corner and then upper right
corner being careful of the two ribbon cables. Note the orientation
of the two ribbon cables in the Step 36
photo. ***500D: For 500D skip Step 35 and continue HERE. ***550D:
For 550D skip Step 35 and continue HERE.
36. Install four screws as shown:
37. Connect the ribbon cable into the white
slider connector using a toothpick as shown. There is no ribbon cable to connect for
the Full Spectrum mod.
38. If you removed the metal ground
shield in Step #17, reinstall it by pushing down on all four corners
until the shield snaps into hold down clips:
Install one long screw as shown. Also install the two short screws
as shown if you removed them in Step #17.
40. Place circuit board into camera body.
Note that on the upper right of the circuit board, there is a
white plastic pin connector that mates with a black plastic receptical
with a hole in it. Make sure it connects fully.
41. When inserting the circuit board note
the routing of the ribbon cables. The circuit board rests on two
alignment pins shown here. Connect the white "push-in"
slide connector and make sure it is fully seated. If you removed
the grounding strap screw in Step 14 instead of bending the strap,
reinstall the screw now.
42. Install screw as shown:
43. Connect all ribbon cables labeled "A"
through "J" in reverse order, starting with "J"
first. Open the "J" hinge connector and use a toothpick
to insert the ribbon cable into connector. I had some trouble
inserting this ribbon cable all the way so I unscrewed the circuit
board and pushed it in with my thumb and forefinger. (This is where
small surgical forceps might have been a useful tool as recommended
by Skyler) . Snap the
connector closed. Using the diagram below as a guide, connect
all remaining labeled ribbon cables through "A".
