How to repair canon powershot sx50

SOURCE: CANON FAULTY SCREEN IMPORTANT READ ME

Only for the brave, on a warrenty expired camera.

Buy a set of jeweller's screwdrivers.

Make sure it is off, with the lens retracted, and remove the battery and SD card.

Remove the 11 screws holding it together

The metal shell is in two halves that can be pulled apart. The rubber socket cover flap has to be removed once one half is off. A rubber gasket round the eypiece lens may drop off - it is easily replaced.

Hold the inner chassis by the edges.

The lcd screen is held by one screw, half hidden under the wiring to the flash - remove it.

Push the wiring to one side just sufficiently to enable you to hinge the lcd screen up on its flexible printed circuit wiring loom.

Underneath you will see the back of the ccd pod, with a flexibe printed circuit wiring loom pinioned under a metal plate with two Y shaped holes filled with brown gunk, and held down by a torex screw locked with some holt melt adhesive, and two further screws inaccessible under the metal chassis to the right.

I hypothesised these were the contacts that become detatched in hot conditions, and (1) tried to shift the flexible printed circuit minutely from side to side using the hole in it (it didn't move appreciably)and (2) pressed down quite hard in the centre of the metal plate, having supported the chassis from below so as not to damage the lens.

I reassembled the whole thing and it worked immediately, with just a faint light smear down the left hand side of the image (the whole image had been completely smeared, then dark, before) which was only noticeable when photographing in dark conditions.

So I took a gamble and it seems to have worked. If it hadn't I was going to break the glue seal on the Torex screw and unscrew and then screw it up again.

Obviously doing this is on your own responsibility.

SOURCE: Canon PowerShot SX100 IS Lens Stuck

If the lens does not extend/retract when the camera is powered on, then lens assembly is damaged.

Unfortunately, such Canon SX100 (and the SX110 too) has a very fragile lens assembly, and it's damaged very easily. Most of the times the internal gears, the plastic post guides and the motor are damaged at the same time, so the only solution is to replace the whole lens assembly.

The lens replacement requires a qualified camera repair technician, unless you want to try in repair it yourself, which requires tools (scredrivers, soldering iron, desoldering tool, magnifier glass with light, etc).

Best regards,

if ur very sure that the battery is fully charged... first we would advice you to change the batteries and see ...... if that doesnt work... the battery contacts may be corroded or bent and hence not making correct contact with the battery
.... sometimes there cud be dust or sand particles in the lens retraction passage... blow out air in those places..... this cud help a great deal.... I was able to fix a similar problem by wiggling the outermost part of the lens.as its trying to go in....
also try Place the camera flat on its back on a table, pointed at the ceiling. Press and hold the shutter button down, and at the same time press the power-on button. The idea is that the camera will try to autofocus while the lens is extending, hopefully seating the lens barrel guide pins in their slots.
if that doest help
Remove the batteries, then remove the memory card. Then install the new batteries, when you turn it on it should come back to life. turn it off, slip in the memory card and turn it on one last time.
if that doesnt help

Insert the cameras Audio/Video (AV) cable, and turn the camera on. Inserting this cable ensures that the camera's LCD screen remains off during the start process. Thus extra battery power is available to the camera's lens motor during startup. This extra power can be useful in overcoming grit or sand particals that may be jamming the lens. If the AV cable doesn't fix the lens error by itself, consider keeping this cable installed while trying the above fixes and 7 as a means to provide extra help to these fixes. But note that I DON'T recommend keeping the cable installed during Fix 6 as you may damage the AV port while tapping the camera. Reinsert the cable only AFTER tapping the camera.



Now we're entering into the realm of potentially damaging your camera in conducting the fix. There is definitely some risk here, so take care when conducting the following two fixes.
Fix #6: Repeatedly tap the padded/rubber usb cover on a hard surface with the intent of dislodging any particles that may be jamming the lens. Other variations include hitting a side of the camera against the palm of your hand. A lot of people have reported success with this method. HOWEVER, there is also some potential for damaging or dislodging internal components with this method, such as unseating ribbon cables, or cracking LCD screens.

Fix #7: Try forcing the lens. More people have reported success with this method than with any of the other methods. HOWEVER, there's obviously some potential for damaging your camera by using this method. Variations include gently pulling, rotating, and/or twisting the lens barrel while hitting the power button. Attempt to gently straighten or align the barrel if it's crooked or twisted. Another variation includes looking for uneven gaps around the lens barrel, and then pushing on the side of the lens barrel that has the largest gap (note pushing the lens barrel all the way in is NOT recommended as it may become stuck there). While doing any of the above, listen for a click that indicates that the lens barrel guide pins may have reseated in their guide slots. If you hear this click, immediately stop and try the camera.

if you felt i've spent my time for u... a very helpful rating is appreciated...

Camera likely has a common short that comes up on the G9 camera. You just need to get the camera serviced and you'll be back in business again. The site that specializes in service for the powershots is: camerasandparts.com They're amazing if you need help with one of these, that's all they deal with. The good thing with them is they do the correction so that common short never comes back again on the G9. Good luck, that's the place if you need help with a powershot model, they're excellent when it comes to service for these.
