    Hallo All :

    My ACD 23" plugged to my G5 Power Tower Quad was working great
    moved everything into another room
    now the ACD LED lights short - long - short - means not getting enough power

    Got a new power brick 90 amp - not solve problem - Same LED light sequence - took both bricks to Genius Bar and the tech there said they both powered up a display properly

    anyone have an idea what I might be in store for

    I have an appt. scheduled for the Genius Bar on Monday morning - dunno - the Genius Bar here leaves much to be desired

    cheers in advance

    I am guessing that you have both ends of the display cable seated correctly. Of you haven't already check that and then check to make sure the g5's graphics card is still properly seated onto the logic board.

    Hallo Blackhand1001 - Cheers for the prompt reply

    Fixed cable on back of ACD so as for that side I cant speak
    2 connections possible for display connection on the G5 Power Tower -
    thought the connections were correct there - will now check the graphics card to make certain is set properly

    report back with news ...

    Hallo :

    Ok - plugged into my G4 PB - same issue with the LED on both bricks

    on the PB - it does recognize the cinema display but is dim recognition as to bright and clickable - though does show brightly resolution options ( 3 ) under the dim "Cinema HD"

    what do you think ?

    cheers in advance:
