Who killed my G9?
Do you have a Canon G9 died suddenly? You would find you are not alone when searching on the Internet.
If you are a G9 owner, you better read this tip, even your G9 is still alive. Why? Because there is a timer-bomb clicking inside! You don’t know when it is going to be triggered.
How to dismantle it? I’ll show you.But take out the battery before reading this tips.
Take off all the screws around the camera. Don’t forget this one.

Remove the ring on the front cover and open up the camera. Can you see some thing weird? Not sure? Keep going.
Remove the screw here.
Remove screws shown on here, and take off the small cover.
Disconnect the cables and remove these screws too.
The screws fell off! This is the one you have seen on Figure 2. Where is the other one?
Here it is.
Disconnect the cable and turn over the board…
These loosen screws will go anywhere inside the camera. They may short the DC/DC board even the main board.
In this case, I found the fuse (shown with a letter ‘R’) was open. I connected a meter, lucky me, the unit turned on!
What is the remedy?
Before I find out the exact part number for the fuse, here is the temporary solution:
1. replace the fuse with a 1A 32V SMD fuse. (I found the current was not over 500mA)
2. put those screws back on the top cover with a little bit Thread Locker.
If the new fuse won’t solve your problem, you may need to replace the DC/DC board or main board .
Is your G9 still alive? You better open it, check it out.
Hi. Superb info and pictures!
Yesterday my G9 just died after opening the lens, realy strange! Now its out of warranty so I guess I should open and check the fuse. A question before I do… the fuse, is it “pull&push” or do I need to solder?
I hope I can get a answer soonish…
Thanks in advance.

It’s a tiny SMD fuse, you need to solder it. Click on Figure 10 to enlarge the picture, then you can see it clearly.
Hey awesome guide…. I have the same problem but mine is really dead.

Thank you. Yes, it’s no problem to link me from your site.
Wow, What a great write up, My dads G7 dead. I think it is the fuse. I found one screw but no luck on the other screw. I have checked the fuse with ohm meter it was open. Where can i get the fuse?
wow.i was suspecting something like that after i found my screw from outside cover where missing.when i open my camera my jaw drop-find two of those litle screw gone.find only one of them.put camera together and got lucky.it’s working like new.thank you for nice tip
Please make sure the missing screw is not inside the camera, otherwise it’s still a trouble maker.
Hi, I had exactly the same problem with a screw loose near the DC board. The fuse was blown. Even though I’m just out of warranty my next step will be to go to Canon and convince them to fix it for free, I think this is clearly a design fault. The strap holder screws should have been loctited in in the factory.
Have you seen this Service Notice for a screw loose on the Canon PowerShot SD950IS?

Doesn’t look like they’ve put out a service notice for the G9 – perhaps some emails to Canon would help.
I have heard some people got free repair from Canon even though the cameras were out of warranty. So if you have a dead G9, try to contact Canon first and tell them it could be the loose screws.
