The Canon G9 has a problem where two screws in the top of the camera work themselves loose over time, then fall out and short out the fuse on what's called the DC/DC board.

This board needs to be replaced, both screws need to be found within the camera (if both fell out), and they need to be put back in place and held in with 'Locktite' so they don't fall out again.

If you do a Google search for "g9 no power repair" you will see in the #3 position Darntoothysam com, where you can have this repair performed for $85 total! This includes the part, installation, and return shipping of the camera.

If you want to do the repair yourself (no instructions included, sorry) you may purchase the part you need for $48 including shipping.

Hope this helps!

Canon powershot s90 wont turn on. used it and took pics and it worked fine. shut it off. went to use it a day later and dead. new batteries didnt help.

If you already tried a second battery with no luck, you'll need to have it serviced. If the camera is over a year, the manufacturers warranty is up. If that's the situation, go to this site All they deal with are Canon Powershot cameras and they do excellent work, the best part is they are much cheaper than Canon. They do really great work on the Canons. That's were a lot of people go for help with the Powershot models.

My canon powershot g9 will not turn on

Your camera probably developed a common short that the G9's sometimes get. You'll need to have it serviced and if you go to this site: they service the Canon Powershots exclusively and they are excellent on these models. It's $89 with them and you get parts, labor, servicing for the camera, and most important they perform the no power correction on the camera too. Shipping is included on the way back with them too. For $89 they're tough to beat. They are experts on these models and the only place I'd go for a Canon Powershot. Good luck with yours.

My canon powershot g9, my pride and joy :(, will not stay on with a full battery. When the battery is fully charged and you press the power button, the lense comes out only half way and the screen does not...

Yes it does sound like a battery problem. Keep in mind that the rechargeable battery is only meant to last a couple years maximum, regardless of use. You may consider a low-cost generic alternative just to troubleshoot. Here's one from Amazon with reasonably good ratings.

My two year old Canon G9 was working fine. I took the battery out to recharge it and now it won't power on - as if the battery is completely dead.

A great place to get help with these G9 no power problems is:
They just specialize in the service for the Canon Powershot models and they are very familiar with this specific problem. The nice thing with them is for $89, you get everything included in their service package for the G9, all parts / labor, shipping back and the service for the camera too. The best part, they include the no power correction to the internal screws for all of the G9's they service. If you need a hand, is the place for service on these. The work is excellent and their pricing and knowledge of these cameras is what I liked.

My cannon g9 camera stopped working. the lens is stuck open and it won't turn on. Any suggestions?

Common no power problem on the G9, you just need to get it serviced. There's a great site that only services the Powershots, they're amazing when it comes to servicing these models. On the G9, they do a fix in the camera so the short never happens again which is great, plus they service up the rest of the camera. They don't charge much and they're amazing if you need help with a Powershot. Try them, their site is: Good luck, that's the best place if you need help with a Powershot problem.

Formatting memory card

First of all, yes, you will lose your pics if you format the card now. Get a card reader and download the pics to your computer. If you've used 1.7GB on a 2GB card, it may very well be full since the camera uses part of the card to write the files.

Won't turn on

Make sure the battery is new or in good shape to hold a full charge. It may be a good idea to check the voltage the charger is putting out. Also test the voltage the battery is receiving and holding when not in the camera.
It may be possible to test this camera with an external voltage adapter of the correct voltage. If you can get the camera started, then go to the menus and set all to factory default settings.
If you still have no results, then I would suggest to call Canon at the repair department and ask questions, and also find how much a repair is. Canon also has a trade-up or trade-in program.
Go to and to the repair section.
This same thing happened to one of the cameras I had which is similar. The external power supply made it work, some problem is internally. Canon had checked it for me, and found internal damage due to water buildup on the circuit board.

My Cannon G9 digital camera wont power up even though I have a fully charged battery?

This is usually from a loose screw inside the camera, a screw inside the camera can come loose and cause a short which is very common on the G9. If you go to: all they deal with is service for the Canon Powershots. They're great if you need a hand with one of these and they automatically do the no power correction on the G7's and the G9's they service which is nice. They are about the least expensive out there at $89 and they include the service and the shipping back. The best part, they do excellent work which is a must for me. Hope that helps you some.

It's a common problem with the loose screws on the G7 and the G9 cameras. The camera needs to be serviced since it likely blew a fuse when it shorted. The site that's really good for help with these is: They just service the powershots and they are less than most places charge. They do wonderful work but the best part is they do the correction for these problem on all G9's they work on so the problem doesn't keep happening. That's where a lot of people go for help with this problem. Good luck with yours.

Blank screen

Did you accidentally hit the lower left "Display" button on the back of your camera? It manually turns the screen on or off to save batteries. Turn the camera on and press it once to check.
