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.
(click on pictures to enlarge)
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.

To disconnect the cable, you need to flip up the black part
of the connector to unlock the it. When you connect the cable back, press down
the clipper to lock the cable.

Thank you! My G9 is working again (for the moment) – I could only find one screw, but I know I’m not skilled enough to dive deeper into the camera’s innards, so I’ll stop here.
After I received my Canon G9 back from service (they did not even check it for loose screw, and I declined $160 flatrate repair), I mulled what to do next. I decided to look inside the camera. After just a few minutes I was able to see enough inside to verify the strap bracket had only one screw holding it. Did not see or hear or find the other immediately. After some more careful (and video’d) disassembly, I located the loose screw lodged up by the viewfinder. But there is still the issue of ‘no power’, and the issue of Canon’s failure to acknowledge this as a G9/G7 model defect. What hope for a Canon turn-around?
***Thanks to xscrewdriver and other posters for tips & how-to.
Looks like I may need to perform this surgery on my camera as well. I have sent mine in already and I received a letter from canon saying it will be $149 to fix it plus tax and shipping. I’m not going to pay them anything. If they don’t fix it for free I told them just to send it back. I was planning on doing a YouTube video of me shooting the camera with my 40 cal and sending canon the link, but now I’ll take it apart and see if I can fix it. Either way it looks like I’ll become a fan of Nikon. I needed a camera so I picked up a S560 and have been very happy with it. I know it’s just a point and shoot, but I needed a camera and the price was right – free

Well i got my G9 back from canon today. I took it apart and one screw was missing and another half out. I’m waiting for my battery to charge to test it.
I’m really upset that canon just took the its out of warranty approach. They must know full well there is a problem with this model. Who knows how many were sent back under warranty.
Oh well i guess they don’t need my business in this down economy.
well no luck – still does not work
@Glenn K
Did you check the fuse? Try to replace the fuse if it’s open.
@xscrewdriver
