I have a Sony A-300 that I have been using almost exclusively for my grandkids ball games. My DGS had a game tonight. I normally use the viewfinder when taking pics as I find I hold the camera a little steadier. His first at bat I took pics and after he scored I went to check them. My live view screen was white with a bunch of lines. I tried everything I could think of and nothing changed. I have no idea what happened as it worked fine last night. After freaking out just a little I called Best Buy and thankfully I have an extended warranty so it will be fixed. Unfortunately I now have to use a handheld for my DGD's dance recital. I have been thinking of a second body so I may be getting one this week. I think I will be getting extended warranty's on all future camera purchases.
