Tip & How-To about Canon PowerShot G11 Digital Camera

Problems with Control Wheel on Canon G11

There have been reports by many Canon G11 owners of malfunctions of the Control Wheel on the back.
This problem often is due to a lubricant used on the G11.
Cleaning the contacts underneath the Control Wheel will resume normal operation of the camera.
I use an electrical contract cleaner I purchase from Amazon. See photo

I don't take the camera apart at all.
I merely use the thin straw-like attachment to the spray can and inject a small amount of Contact Cleaner into the space under the Control Wheel, using the space that is around the circumference of the wheel.

Spray, rotate to distribute, spray, rotate to distribute, etc.

Only a very tiny amount of Contact Cleaner will be necessary.

You have to zoom the camera lens out for that lens to work.

I have a powershot G11. I charged my battery and when I put it back in the camera it won't power on

The G9 has a design defect with screws that loosen, fall out, and short out the camera. I don't think the G11 has this problem, but it is most likely the fuse on the DC/DC board that has 'blown' causing there to be no power.

I'm not sure how much the part costs, usually about $30-40. We repair the no power problem for the Canon G9 for $85 incl parts, installation and return shipping of the camera.

Hi, I've seen that issue before with the G11, it's due to faulty wiring on the circuit board and can only be fixed by a Canon authorized repair shop as fixing that issue is very involved.
