LCD backlight and video half work half don't
LCD backlight and video not working completely. Backlight does not work at all. I used the trick posted in one of the questions/answers about shining a light through the Apple Logo, what I get is the left half of the screen has wavy lines through it, the right side appears to be ok. I have replaced the video cable because the hinges had gotten very loose and pinched the cable so bad that the copper was visible on the video cable. My question is how do I tell for sure that I need a new LCD? I have a picture of what is happening attached.
Is this a good question?
