I have the same problem Mary. The imac starts but no screen and i need to shut down/turn on a few times until i see the normal screen. Very ocassionally the screen blinks too or turns to black and i can only see stuff by flashing a light to the LCD. Where did you buy the LED Driver Board?? Can’t find it anywhere..
