Screen backlight goes out randomly.
I bought a 2011 iMac used knowing that there was a problem with it "shutting off at random times" and I thought I could simply replace the power supply. After receiving the computer I noticed that the only thing that's shutting off was the backlight because I could shine a flashlight at the screen and the computer was working fine. I then replaced the led backlight control board, but the problem persists. Now all i can think to do is replace the lcd itself, but I can't figure out what part would be compatible. Would a screen listed from a 2009 or 2010 iMac of the same size also work? In addition I don't know if there is a better place to buy the parts than eBay. Thanks for any help you can give:)
