Canon PowerShot G9 Disassembly Part I
After 10 years of use, mine is filled with dust in and our of the lens. Time to take it apart and clean it!

The Canon PowerShot G9 made its debut around 2007. With 12.1 mega pixels and 3200 ISO, it's easily one of the more economical choice for amateur and hobbyists.
-
I mean, after 10 years it's still pretty good. The 12.1 mega pixel is more than needed, coupled with a 6x optical zoom to take sharp photos of everyday objects.
-
It got a few scuffs and maybe some dings and some paint scraped off (or it fell off on itself) but it's still very capable.
-
And yep, I did took out that 10 year old SD card. A miracle that it still works after a trip to the washing machine.
-
-
-
For starters, we'll pop out that battery.
-
And the SD card, if you had not done that already.
-
The battery tolls in a good 720mAh @ 7.4 V with a capacity of 5.3Wh.
-
And ... there is a battery-eliminator for the G9 if you happen to take lots of photos indoors. Proof? A trap-door like mechanism on the side of the battery compartment -- for the wires to go in and out.

We'll start
attackingremoving the screws on the outside of the machine. -
Which tolls in at ... 6?
-
I'm not sure if there are screws around the mounting point (for the camera tri-pods). I don't have it on my unit ...
-
I know there will be a LOT of screws, so prepare some
food container... containers.
-
-
-
So this part would be empty.
-
There will be a screw on the bottom holding down the display, so you will unscrew that ...
-
And then you would push the screen toward the bottom of the camera with your fingers.
-
And then the screen will ....
-
???
-
The flex cable had still a long way to go before being "free". Apparently we would need to remove the steel brackets ...
-
-
-
-
So this is how the camera looks like ...
-
I'll DEFINITELY leave that for later. Look at that flex cable. It had a scary amount of connection AND test point.
-
So what are we here to do? We are supposed to remove everything, which includes the motherboard, and then I'll take apart the lens and clean its insides and outsides. Or I think I am going to do that.
-
-
-
We had this ELPIDA DDR3 RAM HB0010A17EE for ... shots buffers?
-
Which is overlaid on ... a processor?
-
We had the Sony D4807GA823DG4V
-
15019GB 7MR4G 07G
-
We had a unnamed IC and another ... IC on the front. But hey ... this one on the back is REALLY eye-catching. A exposed-die processor!
-
Could this be the GPU?
-
-
-
And to remove the motherboard, we will need to remove the top assembly (which appears to be a single large piece) which requires removal of the front ...
-
Cover? Panel? Plate?
-
Start by prying near the TOP of the front plate. There is a plastic tab holding it.
-
Hello .... how are you doing there?
-
-
-
And ...
-
BOOBY TRAP!
-
Sadly, this is largely how it would be done. That tiny connector is for the microphone on top of the machine, near the function wheel.
-
Look at that assembly! It's absolutely monstrous -- the numerous dials, the power button, the playback button, the hot shoe ...
-
Some of which looks unnecessarily delicate, but hey, these are dials. Non-digital dials that use physical contact on every single click. And the copy-paste button (that's how I call it) had its own light.
-
-
-
So how exactly on earth should I do to remove these stuff without snagging a single copper line on these flex cables?
-
Answer: inter-board connectors.
-
BOOM! You're out.
-
Which leave us with this power board ...
-
Apparently the power is directed to the entire "system" part through this single connector, so the board is free to move after the screw is removed ...

To reassemble your device, follow these instructions in reverse order. CAREFULLY. After cleaning the dust. Or, continue to part II of the disassembly.
