Inleiding

This guide covers cleaning ice cream, sand or other debris from the zoom button of a Cannon superzoom camera. This guide should apply equally to the SX50 SX50 SX60 SX510 SX520 and similar models.

  1. The rocker buttons on a Cannon superzoom camera are susceptible to debris entering the cracks.  This debris travels down into the body of the camera where it can interfere with smooth operation.  This guide will cover removal and cleaning of the buttons.

  2. Remove the battery before starting.
    • Remove the battery before starting.

    • Screw management is key to a successful repair. I like using a series of bowls for each side or component of the camera, with scraps of paper to document anything unusual such as an extra long screw.

    • You'll need a small cross head screwdriver, and preferably a magnet stuck to the screwdriver to assist in picking up screws.

    • Optionally a silicon grease and lubricant can be used at the last step.

  3. The camera shell opens easily enough., and all screw heads are visible. The front shell slides straight out, the sides just come off.  Nothing needs to be forced, pried, or unglued. The only tricky part is the back case, which has a fragile ribbon connector.  Unlatch this, carefully, and slide the ribbon out.

    • Optionally, use a silicon grease on the plastic and rubber parts, and a polyphenyl ether (PPE) lubricant on the gold contacts. If you don't have a PPE lubricant a very very light coating of a light lubricating oil also works. This step is optional.

    You only need to remove the front fascia, not the back. Then you take off the top zoom/dial fascia, under which you get to the zoom button/rocker. To take off the front fascia, apart from the screws on the sides, don’t forget two screws in the flash compartment. Pull off the front. Unplug small ribbon connector to the left of the flash (as you look at lens) near another screw. Unscrew this screw. Then the top zoom/dial fascia comes off with a bit of prying - don’t touch big battery capacitor tube with finger or metal, it may have a charge. Under the top plastic fascia/panel are various screws and plates, pretty easy to unscrew these to expose zoom button which must be pushed out from between two small spring levers - easy. Debris gathers with age around inner circular periphery of the plastic zoom rocker. Use a screwdriver to clear it out, and wipe away remains. It will then go back and forth smoothly when assembled back with the two spring levers, as it was when new, without need for lubricants. Reassemble.

Bryce Nesbitt is an awesome iFixit contributor. You remove every screw: as it says above they are all visible from the outside.
