A thick blue horizontal line appeared in my LCD screen and won't go away. I can still take pictures and they print out fine, but how can I get rid of the blue line?
This is probably a problem with your LCD monitor or the connections to it. Does the blue line show in all situations such as record, playback, and menu mode?
Test your monitor by plugging into your camera the TV cord that came with your camera. Connect to a TV and use it as a monitor when your camera is on. be sure to switch to the TV to channel three or video to get a picture. Check the different screen modes: record, play, and menu. If the blue line does not appear on the TV then there is damage to your monitor or its connections. My guess is you won't see the blue line on your TV since you get good prints. If you are on warranty, get it fixed. Otherwise, you have a choice between paying for a repair or living with it. Good luck.
