View Full Version : How to fix Canon camera?

Someone here has a Canon PowerShot SD750 compact camera.
It appears that they attempted to put the battery back in and closed
the compartment door without first getting the battery all the way in.
Now the camera doesn't work and the door can't be opened. It will
start to slide open but stops before it moves far enough to unlatch.
I have just read online that Canon service isn't worth anything.
Whether that is true or not, does anyone have any suggestions for
what we should do next? A website or discussion forum where we
can get more info?

Perhaps a holding the camera upside-down and giving it a couple of firm-but-not-too-hard raps against the heal of your hand could seat the battery?

This site showed a lens repair. He took the back plate off. Perhaps that is relevant to your problem. http://www.cockeyed.com/lessons/canon_sd750/canon_sd750_01.php

For all the disassembly involved in that lens replacement, it didn't open
up the battery compartment.

I expect that the battery and the tiny latch that holds the battery in
place are wedged in by the door, so it might take a hundred g's or more
to unwedge them. WE WILL NEVER KNOW. That would be true even
if it were MY camera.

I'd take it to a local, proprietary (i.e. not Ritz or Wolf) shop with a good reputation. Could be a simple, 10-sec fix. Might not be. Regardless, if they can't fix it, they can sub it out to a trusted service center, or possibly recommend one.

My Canon developed a nasty problem, and I was in Kuala Lumpur at the time. I went into a Canon dealer and the guy said, "you very lucky, they make this model here in KL. I have contacts there I think will sort it for you, but will take a few days". Now either he had a very good spiel to extract a good fee for a simple fix, or I was indeed very lucky.

I would second PetersCreek's suggestion of giving it a couple of firm taps on the battery cover to try to get the battery to pop down into place. If that doesn't work, then probably Mugaliens' idea. :)

Either that or see if you can get a replacement battery cover, then just push/pull/pry the stuck cover until it breaks.

(I just had to go back and put the "y" at the end of all three of my usages of the word "battery," because I had originally typed "batter." All three times. What's up with that?)


I have just read online that Canon service isn't worth anything.
Had a Canon camera that quit working a couple years ago - bad CCD sensor. Canon replaced the camera with a new, higher-end model, absolutely free, even though the camera was no longer under warranty (and I had never even sent in the warranty registration anyway).

I can't complain about their service.

Jeff,

One thing to try before abandoning all hope - get a thin piece of firm plastic (such as that from a blister pack) and insert the edge into the crack around the battery door. Work this gently around the perimeter of the door. It may help to free the latch.

(As an aside, this technique works beautifully for opening certain plastic housings that are held together by internal tabs and not by screws. Prying or pulling these apart mars the case and breaks the tabs, but the thin plastic slides readily between the tabs and slots and pops them free with no damage and minimal effort.)

I can't give you anything more specific to try without seeing the mechanism.

So, the door opens at the press of a button, is that it?

In my experience, cameras don't do well under high g-force.

(I just had to go back and put the "y" at the end of all three of my usages of the word "battery," because I had originally typed "batter." All three times. What's up with that?)Either deep-seated emotional baggage from tremendously violent childhood battering. Or, you're thinking about making cookies.

The door slides out about a quarter of an inch to unlatch it, then it
swings open. Inside the compartment, the batter is supposed to be
stirred until creamy... uh... the battery is supposed to be held in place
by a tiny little latch that should rotate into position after the battery
has been pushed in all the way. My guess is that the battery was
not pushed in all the way, but far enough to make the latch rotate.
I think there must be a spring behind the battery to push it out when
the latch is manually pushed aside. That spring is what would prevent
the battery from being bumped into place by any knock less than one
provided by a baseball batter.

I should mention that if you do deep surgery on a camera (such as unhooking the LCD or the lens assembly) it may require a factory recalibration to make everything work properly again. Indeed, if you check page 7 on this site, you see that he had trouble with the LCD and blurry pictures after reassembly.

Replacing a battery door does not, I think, count as 'deep surgery.'

Jeff: if you do a web search with the terms 'SD750 battery door', it returns a lot of pages. Apparently this was not a well designed part. I didn't see any pages addressing how to clear a jam, but you can find replacement doors for sale, and it's possible that the sellers can give you advice on how to replace the door, if it comes to that.

Can someone post pictures of the battery compartment, door, latch etc. of one of these (working) cameras?

We got the door open!

It is my dad's camera. I took the battery out to recharge it, and
left it to him to put it back in. Turns out he put it in upside down.
The last thing I said to him was that it will only go in one way, so
if it doesn't go in, try a different way. My sister is the one who
did all the analysis and repair. She says that there is a hole in the
battery compartment door, filled by a rubber plug. Yesterday she
removed the plug and tried pushing on the battery through the hole,
but with no result. Based on comments here, I suggested that she
try that again. This time she found a pen cap that fit through the
hole, and while pushing in on the battery with it, she pulled out on
the door. It worked in less time than it takes to read this.
No damage done to the camera! Her best guess as to why the
hole is in the door: To push the battery in when it gets jammed!

Thank you, everyone.

Are you nervous? Is your wife in labor? Better attend to her...


I can't complain about their service.

Neither can I. I sent in my older Canon once and it was returned fixed, without question.

If I didn't know any better, I'd swear their corporate mission was as simple as:

- Best dang optics
- Best dang customer service
- Best dang camera

Thanks much for the higher opinions of Canon service! Obviously the
quality of anything can vary from one occasion to another.
