LCD Power / Boot up issues
I have a 2007 iMac I've been working on. Originally the computer worked fine then I started having issues with it not booting up.
It seemed if I held the power button longer than usual that would allow it to boot up sometimes.
It was a problem with the video or LCD cause soon as it hit LED 3 the machine would quit and have to be unplugged to continue.
I replaced the video card and still have the same problem. The only way to get the computer to boot up is to unplug the inverter cable from the back of the LCD (9 wire black cable). The computer boots up and runs like normal. You can see that the LCD works if you shine a flashlight on it.
From what I've read seems like its probably a problem with the backlight board on the LCD and not the power supply? Is it worth replacing? Thank you for your help!
Is this a good question?
