    Hi, guys!

    I've problem with my iMac. LCD Display shows black screen (no picture at all), external display works correctly through Mini Display Port - HDMI. 4th LED doesn't lit up, only 3 LEDs are lit up.

    I've already changed LVDS cable and LCD Display - problem still exists. But if problem is a logic board or graphics - how external display works?

    The external monitor/display shows the image without problems?

    What do you mean with "4th LED doesn't lit up, only 3 LEDs are lit up."? What LEDs?

    No problems with external monitor.
    LEDs I have mentioned are indication LEDs on logic board.

    Which begs the question, what caused the fuse to blow.
