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?

Low battery power ? (rechargeables do not last forever).

Try a brand new set of batteries

if you are changing the lever to different positions...the green/edit, red viewfinder, or the red lcd view and get nothing...chances are your camera has the same problem mine does. The lever is broken and is not engaging the mechanism internally to change the views or power the lens to fully extend.

you won't be able to take pictures like me. I don't know if there is a fix or not. I guess the camera is prone to these problems as there are a few similar to what u describe with yours.

Try some of the less severe repair techniques for a lens error:

SkiPowder, the E18 error is fairly common. Usually it's sand or grit interfering with the lens extension mechanism. Or the camera's been dropped with the lens extended. Or the camera has been powered on, but the lens had been blocked preventing its extension.
Here's some things that you can do to try to correct it. Have already fixed several cameras with this problem by using these methods:

Guest has a different problem. Guest's problem sounds like it might be a defective CCD imager. If so, Canon should fix this for you for free, including free shipping both ways. This is regardless of your cameras warranty status. Please check the following two links for more info:

Applicable cameras include:
A40, A60, A70, A75, A80, A85, A95, A300, A310, S1 IS, S60, S200, S230, S330, S400, S410, S500, SD100, SD110

Use the audio-visual cable that came with your camera and connect your camera to your TV.  Now turn-on your camera and switch to "view mode", e.g., to see a already taken picture on your LCD.  You will not see anything on your LCD but may see an image on your TV, even if the image is "F18". 

I used the above trick to clear an F18 error on an A75.  Right now I am trying to get the camera to focus properly, but somehow the above cleared the F18 error.

If the above does not work, try connecting your camera to your computer's USB port using the other cable that came with the camera.  Your camera will want to be on, and in the "view mode".  I have read that this trick can reset an F18 error.

Good luck.  At least it costs zero to try these two tips.

there may be two reasons for this problem. 1. may be a defective or broken CCD. 2. the shutter is not working may be due to broken flex circuit cable. in any of the case you have to get it fixed from a professional camera repairer
