Question about Digital Cameras

8 Answers

My Canon G7 appears to have died! It will not turn on. I have tried recharging the battery and after no response again I purchased a new battery, charged it and agin no response. My last action was to successfully download images to the computor. The only thought is that I may have turned off the computor BEFORE disconnecting the camera. Help!!!

    With regard to the offered solution, the only reset button that I can find a reference to in the manual requires the camera to be switched on first!!!

  • bofalive Jul 13, 2008

    I have tried the offered solution before posting my problem, with no success.



    I am still of the opinion that my last action holds the clue. In the Canon Utilities CameraWindow readMe file it is stated that the owner should not put the computor in Standby mode while the camera is connected via the USB port. It explains what might happen to the computor but not what might happen to the camera as a consequence of this action. Has anyone any ideas related to this action which may explain why the camera is inoperative/ dead!

Try cleaning the gold contacts that connect the camera to the lens. Also check that your battery contacts are clean. use soft tissue and isopropyl alcohol to clean the contacts.

Best Buy can help you as well with the camera. You should be able to retrieve the photos with a memory card reader installed to your computer.

HI,

Polish the terminals with a dry cloth and make sure the terminals are clean. If the terminals are covered with oil from your skin or similar matter, this may cause poor contact and power may not be fully supplied to the camera.
Also, polish the battery charger terminals with a dry cloth before charging the battery. If the terminals are covered with oil from your skin or similar matter, this may cause poor contact and the battery may not be fully charged.

Just use a card reader and put the memory card on it so you can get all the data inside the memory of the camera.

Hope that helps........

    There may be a small screw (or other little piece of snot) rolling around in there, but I seriously doubt it came from OUTSIDE the camera.
    I also seriously doubt, (since the electronic boards are sealed from the collecting chip) that it has anything to do with your apparent inability to power up...
    You've probably got dirty terminals in your camera body, or battery (or BOTH)!
    I've found that the best fix 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...

    Hope that helps....

    Did you see this first realease note? Did you encounter this are have done any of this before the camera stop working?



    1) During communication between CameraWindow and the Canon camera, do not unplug the cable between the camera and PC, use the Canon camera's mode dial, memory card slot cover lock release switch or battery cover lock switch. Depending on your PC environment, using one of these may result in malfunctions.

Have you tryed pressing the reset button? if no effect is it still covered by warranty? IT does seem like a hardware proglem.

Does it start if connected to power adapter?

Posted on Jul 12, 2008

  • Ginko
    Ginko Jul 12, 2008

    If it starts when connected to power adapter, then it is a problem with the battery contacts. If it does not start at all, them there is a major problem, probably something blown on the main board, a short, or a broken contact.

  • Ginko
    Ginko Jul 12, 2008

    Check that the battery hasn't blown. Check if the battery released liquid on battery contacts, check also for oxide.

I would try and clean the contact leads to the battery first with rubbing alcohol then after it dries I would try the battery again if it does the same thing then it is a battery problem and you can purchase a new one, it sounds like it is not the camera.

You can use rechargable cells with high current( mA) rating. So try and use any rechargeble cells with above 2000mA . Also you can use a rechargeable adapter externally to charge these cells.

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 power shot G9 won't turn on


If it's under a year, send it in for warranty with proof of purchase. If the warranty has since expired, try this site: www.camerasandparts.com They're amazing for help with these. The no power problem on the G7 and the G9 is most often from a common loose screw that falls out inside the camera and causes a short, resulting in no power on the device. The site I gave you does the internal correction to the screws so you don't have to worry about the problem from keep happening. They're $89 with all of the service for the camera included and the repair and correction and even cover shipping back. The best part, they do amazing work on these Canons, good luck with it.

MY G9 IS NOT POWERING ON


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: www.camerasandparts.com 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.

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?

Canon powershot g5 - battery charge


Take out the battery and put it back and than recharge again. Some times in case of G5 it happens that the camera battery is not properly charged and the indicator shows that its fully charged (i.e. Green light) In such cases battery need to be taken out and than put back again and recharged

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.
