Funky Weird image on 23" Cinema Display; where can I find a service manual?

Hi all,
I bought a 23" Cinema HD Display 'as is' on eBay; the seller had reported that its power light was flashing several times. I found the support article pertaining to this. Unfortunately I had no way to test it at home because it did not come with the power brick, so I did the next best thing. I took it to my local Apple Store and one of the employees hooked it up with one of their demo machines to see what would happen. It powered on, all right, but displayed this funky weird image where it was mostly black with a striped green edge and this very thin jagged strip that looked like the outline of a mountain going from left to right across the screen.
Does anyone have any idea what's going on here--bad inverter board, or what? Also, is there a service manual out there I could download for this display? I have experience working on a wide variety of Macs, from the SE/30 and Classic on up to the newer Powermacs--replacing motherboards, hard drives, floppy drives, video cards, etc., etc., but have never worked on an LCD display or ANY monitor for that matter....
Many thanks for your help!
Sally

Hi-
Here is how to take it apart.
That's about as far as I can get you. Would look for the obvious loose connection, burnt component on board, burnt trace, etc.

  • Where can I find a service manual for Satellite L30?

    Hi guys
    Just wondering if anyone knows where I can find a service manual / engineers guide for a Satellite L30?? I have a broken hinge on my laptop and Toshiba were very helpful in helping me find replacement parts - via Topaz. They were also a bargain at only 8.00 + postage for a pair of them. However......when I enquired about 'how to fit them?' they both became rather 'un-helpful'!!!!
    And I really don't feel like paying PC World the 219.00 they quoted to fit them!!!
    I have no fear of opening and playing around with the insides, but any help or 'pointers' would be gratefully appreciated.
    Many thanks in advance :-)

  • Where can I find a User Manual for Mavericks?

    Is there a Mavericks User Manual? If so, where can I find it?

    Hi..
    There is no user manual per se.
    Open the Finder. From the Finder menu bar click Help > Help Center then use keywords to find what you need help with.
    There are books available for purchase such as OS X Mavericks for Dummies at Amazon here.
    Since OS X Yosemite will be released most likely this month, you may want to hold off purchasing any books for Mavericks.

  • Where can i find a dutch manual for photoshop cs6

    Hi,
    I'm trying to find the dutch manual for Photoshop CS6.
    There is a hyperlink available on this page Help bij Photoshop | Archief called Help bij Adobe Photoshop CS5 (PDF), but if I follow this I end up on an "error page" in English telling me that the requested page isn't available.
    Can someone provide me with this PDF-file please?
    I can download this PDF in English, but it would be so much easier for me to read and understand the subject matter in Dutch.
    So, is there anybody out there who can send it to me?
    Thanks!
    Michael
