550D Re-assembly Continued


36. 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. Place the CMOS assembly unit onto the three springs, by lining up the holes in the assembly frame with the black plastic pins next to the springs. Be careful because the springs are loose and may fall over. Return the three screws with the Torx driver to their original positions using one of the methods you used in STEP #17G. Place a drop of glue over the head of each Torx screw, to keep the screws from turning out of position.

37. Install two screws as shown for ground straps and place black tape over left screw:

38. Connect white pull-out connector to circuit board and slide in until fully seated. Place black fiber optic cable into its white connector. Slide it all the way in using tweezers. When inserting the circuit board note the routing of the ribbon cables. The circuit board rests on alignment pins.

39. Connect ribbon cables J, K & L into their hinged type connectors. Be careful of the large black capacitor and getting shocked. Connect all remaining labeled ribbon cables to circuitboard as labeled below.

40. Install five screws as shown below to secure the circuit board:

41. Push top of camera back down until it snaps in place. Place camera front piece back onto camera body. Start a the top and the bottom will snap into place as it slides over the metal tripod mount socket.

42. Install two screws above the lens mount and one screw below the lens mount as shown below:

43. Install two screws on bottom of camera as shown:

44. Install diopter adjustment screw and cam. The cam is keyed with a wide key and a thin key, so make sure to align it properly when installing.

45. The back of the camera is now connected to the camera body with this last ribbon cable:

46. Close up the camera by sliding the camera back fully onto the camera body. Install two small screws as shown along with plastic port cover and rubber piece:
