I have a Canon GL2 that has thick bars across it on playback. It appears to be more of a problem than a simple cleaning could fix. So my questions are: 1.) Has anyone ever had a similar problem? 2.) How much would you estimate this might cost to have repaired? 3.) Has anyone sent in a repair order through Canon's website and how was your experience? I appreciate any feedback you might have, as it is very disappointing to have my expensive toy stop working even though I rarely use it and take extremely good care of it. Thanks for your help!
