Question about Canon PowerShot G7 Digital Camera

Wont turn on

I was using my canon powershot G7 and suddenly it turned itself off and wont turn back on. I have charged the battery and replaced it but it still refuses to turn on.
Does anyone have any solutions or reasons to why this might be happening? Camera has fully charged battery was working perfectly no abuse, moisture, impact. Yet, does not turn on

Does the light blink at all on it.

Many canons have had this same exact problem and either the owners just purchased a new camera or sent it in for repairs to Canon and I don't know exactly what canon does with them but you can call them and see if they will tell you but I bet they will just tell you to send it in.

But you've probably got dirty terminals in your camera body, or battery (or BOTH)!
I've found that the best fix if this is it is to (CAREFULLY!) clean any build- up on the contact terminals between you cam and battery with and ordinary pencil eraser... Make sure you don't leave any eraser crumbs behind...

Many times, if the camera senses an intermittent power supply, it will shut down before it even powers up. I've found this to be the 'culprit' on several cameras I have worked on and repaired... but have never had to work on this canon camera

Let me know if this works or if you need any more help

Is it possible that the battery contacts are dirty?


also, on some other electronics, I've had sucess trying this:

remove the battery and the power cord. hold down the power button for about ten seconds, then release.  wait another minute, then re-insert the battery.

the camera may also require warranty repairs, if those two solutions don't work.

Did you recently purchase this model, or have you owned it for a while? Has this happened to you before or is this the first time you have experienced this issue?

I can tell you, as an Avid Nikon user..which isnt much different from Canon since they are huge competitors of each other..that this might be a defective battery. I'd recomend contacting the manufacturer or seeking on their website, if they list it, as I know nikon does, and see if there are a select serial number and manufacturer dates on a battery for your model. Nikon had this for their D50 and you might also want to make sure the same thing didnt happen to yours..chances are they might of shared the same OEM battery..

let me know how that goes. We can work on other steps as well...

It turned itself off and wont turn back on


Hello :

It seems that the batteries are dead [ can't be recharged anymore ] . You need to replace them with new batteries . If you are sure that the batteries are fine , then you may check the base where the batteries set . Maybe it's rusty or some isolation stuff on it . If it's clean , then I recommend you to get your Cam to the service .

good luck .

Camera wont turn on


If you bought the camera in January, it's still under warranty for a year. When you get home call 1-800-OK-CANON to arrange warranty repair. They're usually very good about it, and will try to make things right.

Canon g7 dead wont turn on My Canon G7 wont turn on. I have tried new battery without succes. Please help nlthomsen@hotmail.com


That's a loose screw issue inside the G7 and the G9 that is common. The best place I know to get help for that one would be camerasandparts.com They just specialize in the powershots and they are awesome if you need help with one of these. Best of luck, they have your exact G7 no power problem right there on their site. I hope that helps.

Canon Powershot G7 just wont turn on... for no reason I can tell.


Usually you can't hear the loose screws in these when they fall out and short out the camera, although many people will say you can. When you have no power on a G7 or a G9, it is most always that loose screw problem. The screws inside should be corrected at the time of the repair so the problem doesn't happen again later. The site that is great for help with the Canon Powershot Camera problems is: www.camerasandparts.com They are great with these and that is all they specialize in. I would see if they can help, they're amazing if you need a hand with the Powershots, plus they do that no power correction on all G7 and G9's they service which I like. Good luck with it

Cannon G7 need help


Hi
Had the same problem a few months ago.There was a high pitchedwhisltle and I think the screen said "lens fault.turn off camera" or something similar.Bought a G9 to replace as the 7 was out of guarantee but sent the 9 back to the e-bay reseller as it was obviously secondhand with grit around the lens ring and the viewfinder.Ebay never again!.So 3 months ago ago I tried the G7 again with a fresh charged battery before I consigned the camera to the loft.I noticed that each time i switched on the whistle and message was there but the lens extended slightly further each timeso I kept rebooting until the lens was fully extended.Turned the camera off and on again and everything was back to normal.It seems that this may be Canons protocol when a camera goes back.Its been absolutely fine until today.It wont boot up at all.I have tried 2 fresh charged batteries and its dead.Any ideas anyone?

Powershot G7 Camera won't turn on.


Same issue happened on Saturday. Only difference was the lens cover didn't completely shut when I tried to turn it off. I turned it on then off again and the cover shut....but it wouldn't turn back on. I fully charged the battery, but nothing. Tried two different batteries.

I was going to take mine in today to Wolf Camera in CO where I bought it.

Note that the camera was fully cleaned and and a new lense added less than a month ago by Canon (through the warranty program through Wolf)

Thougths?
Did anyone get any feedback?

Wont turn on


It may be the SD memory card causing the problem. I just bought a G7. When I turned it on without an SD card, no problem. I put it my old cheap SD card and it wont turn on. I take out the memory card and battery, then insert the Canon SD card and battery and turn it on, no problem.
Hope this helps someone.
