I need to replace a broken LCD view screen, so would like to purchase the LCD and repair it myself. Looks like the entire camera body needs to be dis-assembled in order to accomplish this task.
TOP COVER. Obviously , to many steps that make it tough to post completely on here. I added the service manual to the device page. Page 3-3 and on will show you all you need to know to get the job accomplished. Go to this page, scroll down to Repair Documents and click on the blue canon-powershot-g3.pdf link. Hope this helps, good luck.
