Also, if you've have taken one apart, how long are the CCFL's and what diameter?

I'm trying to find some replacements.

Thanks

I have no FireWire ports on my Laptop so i can’t try out the FireWire capabilities.

I tried the USB connector and Windows detects it as „generic USB Hub“ but doesn’t detect USB devices or flash drives plugged into the monitor.

I don’t have a DVI port and I ordered an adapter so I can’t test connectivity yet.

Does it need a video signal to turn on? I’ve been holding down the touch power button, Double and triple pressing it - no avail.

am i doing something wrong?

So, even when using the new power supply plugged into the wall the power-on light on the monitor remains dark.

My regular repair shop says can't be fixed, but I noted that mother/inverter boards are only $50 online. Can anyone tell me if they are mistaken and that it can be fixed or does it sound like time to take it to the recycling dump? (i.e. replace inverter board).

I have a faulty 23" Apple Cinema HD Display that powers up but no video is shown. However, led power light flashes 3 times. Does the 3 flashes of the power LED indicate the nature of the fault as I can repair if I know what was wrong.

NOTE: I usually have it hooked up to my Mac Mini 3.1 (late 2012) with 16GB RAM, NVIDIA GeForce 9400 w/256MB VRAM.

NOTE: Light on monitor does not light up now.

Well I'm on a quest to repair my HD Cinema Display, rather than replace — or at least I was until I just saw this. Opened up the casing to find this major blow on the main logic board.

Can anyone tell me what this is and what would have caused it?

I have already procured the following replacement parts (which can be returned):

• New 150W Power Brick & New Power Cord

• New DVI/Firewire/USB All in One Cable

• Tested but previously used Logic Board

I am wondering what function this orange square serves and what would have caused such a blow out so that I can treat the root problem as well as the symptoms.

UPDATE 7/2/15: Helpful advice! Upon further inspection I realized it was not actually the orange square, but was in fact, the sections directly below it that blew.

Any advice, input or guidance would be much appreciated!

Thank You!

2009 MacPro 2 x 2.26 Ghz Quad core Intel Xeon / 32 GB memory silver tower (Model No.A1289). 30” Cinema HD Display aluminum monitor with 2560x1600 resolution. Bought new - its a beautiful display and once a primo $5K workstation. I’ve been running OS 10.6.8 on it to continue using some obsolete legacy apps I happen to love. I also own a newer 27" iMac.

From the beginning, this display got very hot, so I’ve always had a small quiet fan blowing across the back of it. Starting years ago, for no apparent reason, the monitor would intermittently go “completely black”, usually after a few hours, while I’m doing nothing more than typing or moving the mouse. And the tiny green light in front bottom right goes out. After a few minutes, it might flicker back on and stay on, but eventually go black again. At first I’d restart the MacPro, which often helped. Then it didn’t help. I asked around, tried zapping PRAM and firmware updates.

Experimenting, I found the oval/racetrack-shaped plug connection (don’t know the proper term) in the 3-way cable that connects the monitor to the “Dual-link DVI” adapter brick (Apple HD Display 150W Power Adapter A1098) may be the problem, because unplugging and replugging it fixes the issue temporarily. But invariably, after some time, the monitor goes black again. As time goes by, I’d unplug/replug this adapter connection plug 3, 4, 5 times a day. Eventually after many mos. of unplugging & replugging, even that won’t get the monitor going again.

So I found a used adapter on eBay ($75+) and replacing it seemed to fix the problem. But after a few months, up to a year, the monitor starts to flicker/go black again. Frustrated, I buy another adapter, which gets the monitor going again, but eventually stops. I did this many times over the past 7 years. At this point, it seems likely I’m buying others’ problem adapters. Now my 5th used adapter no longer works after only 2 months, the plastic plug guard on the cable from the monitor has broken and it looks like replacing the three-way monitor cable is the only way forward.

I’m finally posting this request for help in exasperation. Thanks for reading it all!

Is there a way to confirm what the problem is, that replacing the cable would fix it? (e.g., could it be a logic or power board or graphics card?).

Is a cable still available? How to get the right one? Saw reports the 3 way cable is non-existent

Can I replace it myself without much tech experience? Checked this ifixit guide and viewed this Youtube video and think I could manage but never done anything more than swap in a graphics card and memory.

What I’ve tried:

- Unplugged replugged the cord from the MacPro to the DVI adapter

- Zapped PRAM

- Contacted Apple (“Obsolete hardware and systems aren’t supported”)

- Replaced the DVI adapter brick (5 times in 7 years)

- Asked for help on the Apple forum. Determined that its unlikely a graphics card or firmware issue

- Read numerous forum posts including:

• 27” Cinema Display turns off randomly

• How can I fix my display blacking out intermittently?

• I have a 30 inch Apple Cinema Display that just went blank

• Apple LED Cinema Display 27" LED Panel Replacement

• Apple Cinema HD Display 30" Teardown

- Shopped around for other 30” monitors, like this Dell UltraSharp U3014 But a reviewer states it requires a DVI dual link adapter system to work - which is apparently the same thing causing the issue with my Apple monitor

Heres my current adapter. I've kept the last 2 as well, thinking it may not be the adapters at all, but they are identical to this one. For all its life until only a few weeks ago, the (4-way) cord built into the monitor looked newish, but the plastic casing broke recently after I used a clamp to hold it in place into the adapter in frustration. It still worked for a time even with the guts exposed but admittedly it now looks like this is clearly the current reason for the problem even though thats not necessarily the case. I've cleaned the plug shiny many times over the years - and the hole as well - and that made zero difference, so now the metal is tarnished from constant plugging/unplugging.

Thanks for trying to help me!

Had high hopes posting my question here would lead to getting help to fix my monitor. Anyone?

I just purchased two Apple Cinema Displays - both "30". I checked each display before I bought it -- worked perfectly. However, after driving home with the displays and plugging each into my MBP M1 via a separate USB-C to Dual DVI adapter, one display works perfectly (and is detected as Cinema HD), but the other display is showing just a black screen, and the LED power indicator is also dark, and is detected, but not as a Cinema HD display, but as "Display". Any ideas on what I should do?

This is what the System Information shows:

I would like to know the pin assignments for the power adaptor of an Apple Cinema HD Display.

I need to know the Voltage Supply for each Pin of the 5-Pin connection-cable for the original Cinema HD Power Adaptor.

I need to test this display as the original adaptor is broken. I would like to supply power with another adaptor accordingly.

I guess the pin assignment is the same for the 20", 24" and 30" models.

Any help is much appreciated.

I have an Apple cinema display 30-inch 2007. I can't get the resolution up to 1280x800. i changed all connections dvi, hdmi. I work with a 2013 Mac Pro 6.1 and a 2010 Mac Pro.

I have two 30-inch 2007 displays and one works fine at 2560x1600 resolution. The other connecting to the same computer only gives 1280x800 resolution.

Is there any new firmware someone could help me?.

What do you think is the fault?

Thank you very much. Regards Harry Macias

What I find particularly weird is that whenever I plug the Cinema Display’s USB connector into my laptop and my external Apple USB Keyboard into the Cinema Display’s USB inputs, the external keyboard is fully functioning and able to control my laptop. I guess this could mean that the screen does get power to some extent and is not fully dead? I wanted to test the power adapter with a multimeter, but does this mean that I need to take the power adapter apart to do so?

I’ve tried ‘the Jacobeon method’ (covering the middle pin with tape) with no success. Furthermore, I’ve considered buying a 150W adapter to test if it can make the screen work, but as I’ve only spent 35$ on the screen and 90W adapter in total I’m a bit hesitant to spend more than 50 $ on Ebay on a used power adapter that may not fix the problem. It could also be a faulty logic board….

What should I do? Can I fix it myself (I’m a rookie in electronics), should I try to get it fixed by a professional or is it more reasonable to simply toss this beautiful yet fairly old screen?

Does any one have the same problem or has seen that before? I'm trying to find out if it can be repaired or at least find out how these noise / distortion could be described because I can't find any thing on line that relates to it.

It is quite weird as the screen works fine as long as there is nothing too bright on the screen, but as you can see, even when a white / light grey or any other color that could be quite bright comes up is holds up, but as soon as one of these bright pixels goes to the right side of the screen is when the noise happens and invades the whole of the screen...I've never seen any thing like it before...any help or comments more than appreciated!
