I have weird issue with my camera. LCD is working and I can see the menu, but when I turn on the live view screen it looks wavy and a big blue line is showing up on the bottom of the screen. Also, I can see one dead pixel when I turn it on the live view. Camera section is working but I cannot take a picture or video with live view. Do you know what would be the problem? I would appreciate it if anybody could help me with this issue.
