Good Day My friend has a CANON Powershot A80, and suddenly there appears red and white vertical lines across the pictures. Do you have an idea what the problem could be? Thanks

Check your white balance...it may be set to something other than "auto white balance".

this is a common problem for these a80s and a whole bunch of other canon a's, call 1800 ok canon in canada or google ccd recall canon..

canon powershot A470 problem when i click photo then white image come? but when i use it night it is normal. but during daylight or with sunlight.. white image appear....and every time i take a picture there's a horizontal line appears in the picture..

Your CCD image sensor is failing. Believe it or not, Canon will fix this for you for free, including free shipping both ways. This is regardless of your camera's warranty status. Please check this link for more info.

I had the same thing happen to me last November. Canon has a recall of sorts on a wide range of older cameras. Apparently there is an issue with the sensor. Canon will fix the camera free under this recall program.

Here is a writeup of my experience with Canon's customer support (good):

and a direct link to Canon's site

There is recall on this model for this problem, Go to Canon USA web site, Look up Service advisory, CCD malfunction N/C to repair.

The matrix is dead. Probably because of an intensive light got into the lense while the camera was in night mode. It's dead. Nothing can be done.

This 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 camera's warranty status. Please check the following two links for more info:

sounds like you have a vertical sweep problem. Where the fault lies cpuld be the vertical output IC the verticle b+ feed, could be the capacitors in the vertical circuit?? Your gonna need to troubleshoot thr vrtical circuit if your not a tech thin my advise is to take the set to a pro for sn est. Good Luck
