    Is the ACD connected to a Mac, and if it is, what exact Mac is it and how is it connected?

    For the lost cause:

    Have you also taken a look at MRoogle, since that question may have been asked several times?

    I just checked with apple and it says if the light is blinking in a pattern of short long short then its my power supply.

    You might want to try this trick:

    "For those of you who don't want to spend +$100 on a 150W adapter may want to give this a try:

    It turns out the middle pin in the power connector is a ground. When it read an incorrect voltage it makes the displays inverter turn off to protect the unit. One way to circumvent this is to cover the middle pin in the cord going from the monitor to the power brick. I used a piece of paper in the shape of a "W" covering just the middle pin. I double folded a piece of paper and folded it over the plug and down into the connector and then gently pushed the plug into the power brick. Once i did this the monitor popped on and all was good in the world... " from Jakobeon in Apple discussion forum

    Ppl report it solves the problem..

    Took the monitor into apple today and they tested the power supply and that was not the problem. They said the monitor is getting power and the computer recognizes the monitor and what model it is and the resolution. Does anyone know what it could be ?
