Thanks to anyone able to help. I hardly ever use my G12 but took it out again last week. It worked well, I shot video, uploaded to computer, I put camera away safely, etc. Today I took out the camera again and tried to shoot but the display after the menu is construed in violet hues. This isn't an LCD screen issue because the start up screen and menus appear normal. And when I point and shoot using the view finder, the photo displays as similarly distorted. I have tried to AF-assist beam toggle to ON and OFF. No change. Tried resetting the settings completely: same. Tried LCD brightness adjustment: same. Any other tips? I really doubt this is an issue with a wire or dropping the camera unless a ghost lives here and drops my camera when I am not around. Thanks again.
Since the video was uploaded to my computer, I deleted it on the camera last week. No issue at that time. Today, I took these images of my camera screen with my cell phone's camera. First purple one is what my camera sees. Second with the white stripe to the left is the image it displays when I use the flash to take a picture.
Oh, how sad. Ok, well, since this looks like it would most likely be headed for the garbage, I'd be down to replace the image sensor myself since I'm a bit handy and a former USMC electrician plus a wrencher on my mcycles. Is it possible that Canon supplies image sensors for replacement? Thanks again so much.
