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.
sorry the fuse on the main board of the canon g9
I have a rattle in my G9 – so I think I have a loose screw.
I want to put it back, or get it out before it kills the camera.
But….
What is picture ‘F6′ off?
I can’t see what part of the camera that is?
Just taken my G9 apart, and someone has already been in an applied a red anti tamper type soluttion to these two screws! was this fix made by the factory on late models – my serial number is: 6731403980 – not sure where this lies in the production run. (I bought it second hand so I don’t have the full history…
Good luck, It was worth a look – I can use mine again without fear!

In Fig 5, how do you remove the ribon cable from the white plastic clip? Do you lift the clip up or just pull the cable out? How do you replace this cable?

@Bill Lucas
Bill, there is a little black flap on that, flip it up and the cable will come right out.
I now cant figure out how to take off the other type of clip. Flat white clip no black holding the LCD on. Does anybody have an idea?
@Bill Lucas Lift the small black lip at the bottom and the cable slides out, reverse to refit.
Mine suddenly died today. So I removed the cover, and guess what… there was a tiny screw rattling about between two circuit boards. I’ve had it for 2 years and bought it second hand. Nothing to do? Just buy a new one?
Hi,
just to report that I opened mine – it had rattled for a while before it died. a loose screw fell out – I put it back together again and it works! – so fingers crossed and thanks for posting this.
Funny thing happened today. My Cannon Powershot G9 stopped working. I recharged the battery and it still did not power up. It is out of warranty
Hey, thanks a bunch! There was only one screw loose for me. Put it back and everything works great!
Figure 5 Cable was a bit vague, I just pulled it out… But then I saw Bill’s comment -_-;
Besides that great post!!
