    Hi,

    I have a 23" Cinema HD Display. It turns on, my Macbook Pro can see it in the Displays panel but there is no visible picture actually on the screen.

    Any thoughts / ideas on how to get it working again?

    * The power light does not flash any diagnostic pattern.
    * If I shine a torch to the display I can't see anything, not even faintly.

    Do you have any other computers you can test it with?

    Hi there,

    I'll soon have a Mac Pro up and running but until then I've only got the laptop. I did however test the laptop running a Dell monitor at work without any trouble. Do you think it's potentially the macbook pro?

    Could be anything in the system. The MacBook Pro, the adapter, the cable, the monitor, God...

    By process of elimination then...

    - I plugged the monitor into the Mac Pro and the same problem: Power light on, no diagnostic flashing pattern; recognised by the system.
    - The power adpter is brand new, so I'm ruling that out.
    - The cables are permenantly secured to the monitor, right? Any recommendations as to how I could replace the DVI cable?

    Many thanks

    Apple Cinema Displays can be mailed in to Apple's service depots under the 1 year limited warranty or the 3-year AppleCare Protection Plan. I think AppleCare can send out a replacement USB/FireWire/DVI/power cord though, try giving them a call.

    MBP plugged into refurbished (just received in mail) 23" display - blank desktop

    I just got my refurbished 23 inch display for my MBP and plugged it in as instructed, but the desktop on my MBP does not show up on my display? Is there something I'm supposed to do beyond the plugging in / turning on phase that makes the two talk to each other?

    JediMeister, no apple care I'm afraid. Trying to troubleshoot the problem myself. Not sure it's even the cable, so still researching in forums and so on.

    jnasca. Once pluged in as you previously stated open the following control panel
    System Preferences> Displays>
    You should see a picture of the monitors, side by side. Drag the screens into the arrangement you have them on your desk. I think that you can from here then set the 23" to have all the toolbars etc. Good luck.

    Any more thoughts on trouble shooting my monitor - checking the cable?
