[SOLVED]iMac 27" 2011 no backlight

Make sure to check for damage/shorts on the backlight LED cable first.
After that probably the usual LED strips inside the LCD. Completely rip apart the LCD, take out the 2 LED strips and reflow all LEDs and the 2 connectors. If this is the first time you will probably destroy the LCD so be prepared to buy a new one. Or find a cracked/scratched one to practice on first!
