Blown 23" Cinema Display -- main board? or Inverter?

I bought an Apple OEM Nvidia Geforce 3 for my G4 Cube, and the idea was that it should power my 23" Cinema Display (clear). But the monitor became blown when I connected it to an incompatible video card -- although the power light comes ON, the screen fails to illuminate.
I'm hoping that someone can contribute to a diagnosis of my Display's problem. Here is the situation:
The online Authorized Reseller "The Mac Support Store" sells various parts for this monitor. There appear to be two choices:
1) The main board for the 23" Cinema Display is offered here:
http://www.macsupportstore.com/product.asp?pf_id=922%2D5582
and...
2) the inverter board is offered here:
http://www.macsupportstore.com/product.asp?pf_id=922%2D5581
But which one should I buy?
I realize this is pretty lame, inviting a stranger to diagnose a monitor he's not seen, but... you never know. Maybe you know what you're talking about. You probably know more about it than I do.
Is there a good reason for suspecting that the blown Display is the main board? Or the inverter board?
Thanks.

Hi,
I don't know whether this will be of help but last year I started having all sorts of problems with my 23" Cinema Display. I replaced the power supply 'brick' - but still had problems (blank screen etc) - read lots about issues with these displays. I was running 10.4.11 - In the end I tried re-installing the system on another drive up to 10.4.8 - and it's worked fine ever since (it also cured a number of other weird problems) - ok, so I can't get the latest itunes software - but at least I have a screen that works. It seems that anything above 10.4.8 causes problems on my G5 Dual Power PC.

WANTED! L.G. Phillips Main Board out of 22" Cinema Disp.

I have a 22" Clear Acrylic Cinema Display. The inverter board went bad so I got one and installed it. It woks fine, I now have a backlight. However, in the process I managed to break the little (miniature) white hold down tabs on the digital main board. They must have become brittle with time. They break off very easily. It's NOT the main board (in the middle) that the power and signal go into but there is another board (on the far right side) that has (2) ribbon cables top & bottom that I assume create the video signal. Anyhow, I Googled this board and found only ONE on the whole internet and it is in Liverpool England. I don't want to order/buy that far away.
Does anyone have a broken 22" or 23" cinema display that may have a good video board with known good ribbon cable clasps.
Below are the specs I have found:
This LG Main board comes from a 22" Apple Cinema Display with a native resolution of 1600x1024. This board screws into the frame behind the LCD.   Product Number: LM22OW1 Control, P/N: 6870L-C016F.
I have a picture of it but can't seem to put it in this post.

How can I set up Cinema Display as a main screen and leave my macbook pro as a second screen instead?

How can I set up Cinema Display as a main screen and leave my macbook pro as a second screen instead?

I learned that the Dock is positioned at the chosen edge of whatever Display is positioned farthest to that side. E.g. for the Dock to be positioned on the right side of the Cinema Display (instead of the right side of the MacBook), the Cinema Display must be oriented (by dragging) to the right of the MacBook monitor on the "Arrangement" tab of the Displays Preference Panel.

I'm trying to connect my 30" Cinema Display to my new Mac Pro along with a new Apple 23'" monitor. The new Apple monitor is fine. On the cinema monitor everything is blown up pretty large. Any ideas on how to solve this?

The 30" display needs a DUAL-LINK adapter.

Where can I purchase a Logic Board for a 24" Apple Cinema Display?

My 24" Cinema Display started to flicker and black out shortly after I purchased my most recent MacBook Pro. Apple felt that the issue was the MacBook Pro so they replaced it. The problem continued so they suggested I take the Cinema Display to the Genius Bar. The display was out of warranty and the Apple Genius felt the issue was a bad display even after I told him I smelt silicon burning just before it went out completely. He said that he could "depot" the unit and have it repaired for ~$600. Due to the high cost of repair, I chose to purchase a new Thunderbolt Display instead. Recently, I opened the old Cinema Display and found that the Logic Board is fried. I have ordered a new board from 2 different Web retailers. Both accepted the purchase as "in stock" but then stated they could not get the board from Apple. Where can I purchase the Logic Board for a 24" Apple Cinema Display?
Many thanks!

I was very interested to read this document. I think there is a problem with the Cinema Display and that it is frying the computer.
My husband bought each of us a macbook pro. His was hooked up to the cinema display. After about a year, his MBP started to suffer intermittent failures where it would suddenly shut off and have to be hard rebooted. After 2 years, the power or logic board on his MBP completely failed. He bought a new MBP and a Thunderbolt display, and I inherited his Cinema Display for use with my original MBP.
After one month of use with the cinema display, my MBP started to have the same problems. It has to be hard rebooted almost every time I disconnect or reconnect with the cinema display. I went to the Genius bar, and they confirmed that my MBP logic board needs to be replaced; I'm just holding out until spring break to take it back in, as they say it may take a week. Fortunately, I have AppleCare for my MBP.
Our cinema display is 3-4 years old, but it looks like, even though it appears to be working, I should probably get rid of it. I can't keep frying computers!
I'm posting this because I'm wondering how many others are experiencing this problem.

Which type of logic board is compatible with my 23" Cinema Display?

I have a 23" Cinema Display M9178LL/A - A1082 with a faulty logic board and I have noticed that there seem to be multiple types or models of logic boards for this display. How can I determine which boards are compatible with my display?

Hi there...
Could you please describe the symptoms that makes you think it is the logic board?
I have 2 of the same display as yours - I have one 23" that does not power up at all and I am trying to figure out how to get it fix, and the other has the light blinking issue (short-long-short-pause) that I got it to work with a paper strip in the middle pin of the power connector.
Thank you,
John

Replacement logic board for my 20" cinema display?

I'm looking for good place online to buy replacement logic board for my 20" cinema display. Any suggestions?

You could ask the Apple store to let you have (or buy) one of the boxes they use to send the displays in for repair. They should have these on hand.

Main board has blown 3 times in last 10 months on 39" smart tv

I bought the 39" smart TV aug 2013.
It has been repaired (under warranty) 3 times to replace the main board.
The symptom of the TV is it goes only to a black screen, the green LED on the front stays ON, it cannot be powered on or off by the remote or the power button. Only unplugging the TV will 'turn off' the tv, which is only a black screen. Plugging the tv cord back into the outlet and it immediately is power on with the green LED light ON at the front panel.
Anyone have this issue, or know why a main board blows ~ every 3 to 4 months.
Also what recourse of action can I take to get a new TV? This one is a lemon.

You'd need to talk to customer support about that. I'm sorry to hear it.

Cinema display won't turn on

So my cinema display will not turn back on if I have it on, remove the cord from computer then try to put the cord back in. However if I put the usb back in and put my mouse in the cinema usb port the mouse still works. I restarted my computer and the display turned back on but I am afraid of ever taking the cord out again. My main computer is a MacBook Pro.

I have an early 2011 MBP and a 27 inch Cinema Display. Sounds like I am having the same issue. So far, no solution.
If I unplug the MiniDisplay port cord (All Original Apple cables) from the computer, when I try to replug in the MiniDisplay Port cable - the Cinema Display does not activate. I must try several unplug-replug ins to get the Display to light up. Usually takes about 10 attempted unpluggings and replug attempts for the display to come to life.
An SMC reset - has not effect.
I am now on my second Cinema Display - My first display was replaced at the Genius bar - they said it had a defective "logic board". The second display - operated normally for about 6 months, but over the past month has been exhibiting these same problems. I still have a bit of time before the one year anniversay for the Display so the warranty is still valid. Given that this is the same issue that happened with the first display - I guess I will need to buy the extended warranty. Don't like the idea of having to pay to have this problem fixed on a regular basis.

Cinema Display not detected

I got my 20" Cinema Display back from repair today (backlight problem) and now I can't get my MacBook Pro to detect that it's attached. While it was at the repair center, I used a CRT as a second monitor. So today, I just closed the MBP (didn't shut it off, which I think is what cause the problem), disconnected the CRT, connected the ACD and opened the MPB back up. Completely black screen, with the little LED on all the time.
So, troubleshooting:
- The MBP still detects the CRT
- ACD is detected by both a G4 and G5
- A different 20" ACD is ALSO not detected by my MBP
- Reset NVRAM and SMC
- Booted MBP in safe mode
- Booted MBP from startup CD
- Tried various resolutions while the CRT was connected, thinking maybe it was stuck on one that's not compatible with the ACD
- Moved and recreated the com.apple.windowserver.* files

Been messing with this for four hours, and I still have a blank display. Any other ideas? From one thread someone mentioned replacing the logic board fixed a similar problem.

UPDATE:
I just got back from my visit to a mac genius. Of course Murphy's law was in full effect! With my MBP connected to the cinema display in the Mac store, everything worked as it is supposed to.
Well, I rush home thinking that maybe mine would now work - - no luck! He did suggest that I try connecting analog with the provided dvi-to-vga adapter. This suggestion DID work! BUT, I want my video digital! That is why even though I was happy with the iBook G4 that I bought last year, I wanted digital video + expanded desktop!
I think I will make another reservation with the Mac Genius, but this time, bring my monitor. Will keep you posted...

Want to use a TV as a third monitor for Digital Cinema Display....HELP!

Hey Guys,
Here's my set up, please tell me where I am going wrong:
I have 2 22" LCD Monitors that I use for my main work. I added a second card to my MacPro so that I could add an additional monitor. Now I have a DVI to HDMI cable going to my Plasma that I want to use as playback for clients and such. Here's where it gets weird... In After Effects, I can use the Plasma in Digital Cinema Preview for Playback and Previews...works great. Then, when I open up Final Cut I have problems. First, when I go to "Digital Cinema Desktop - Full Screen" it display one frame and stay on that one frame even during playback. So then I changed my Sequence settings thinking my TV couldn't handle that Sequence. No I get a White Screen with no playback at all, not even the one frame. Now the weird part is that if I change the TV to my "Main Screen" in Monitor Prefs, and set Digital Cinema to "Main" it plays back fine. So, if I can playback with it as my main, why can't I playback otherwise? And...if it works in After Effects, why is Final Cut Having Problems with it? It's set to "All Frames" and "Desktop Mirroring". Thoughts? I have seen this set up work before...what am I doing wrong?

I'm trying to find out much the same thing. I would assume that anyone knows the answers can help both of us.
I'm purchasing a new Mac Pro desktop. I also use final cut but not after effects.
I actually have 4 monitors to choose from. 2 Dell 19" - One 27" Apple cinema display and a spector High Def 1080i monitor that has a DVI input.
I would like to use one of the Dell's as my primary home desk top monitors with folders and all the usual dock and stuff. I would like to use the cinema display as my primary final cut work surface.
I would like to use the HD monitor to show HD footage and use it as a client monitor. Remember it has a DVI input.
I've talked with the folks at the Local Apple store and they are not sure if I will get a real HD signal on the HD monitor if I add a second radeon 2700 card to the computer and take on of those DVI outputs and attach it to the HD monitor.
If thats not possible can I use the apple cinema display as my playback monitor?
Or do I have to go with a conversion box like a mxo, AJA board, or decklink box.
The goal is to have two monitors for the program and One monitor in HD for the client monitor,
Thanks everyone in advance.

Cinema Display 27" with iMac 24" Early 2008

I want to connect my Cinema Display 27" to an iMac 24" Early 2008. I recently bought two adapters, one from Mini DisplayPort to DisplayPort and another one from DisplayPort to Mini-DVI. Unfortunately they won't work together. Before I continue buying more adapters I wanted to ask here, if anyone has any experience with this combination and can recommend working adapters to me. Thanks in advance.

I've seen offers on the web for services which will replace one graphics card for another in an iMac. You pay for the hardware and the service, and the service... ain't cheap... because it's not a trivial operation. I would never spend the money to have this done, because there will still be no certainty that things won't go kah-blooey later.
I sympathize. The iMac I'm currently using blew out its logic board two years into its three-year AppleCare warranty. It was replaced at no cost to me, of course, but as you pointed out in the case of your iMac, this was a well-known issue. And if it were to happen now, I'd be SOL because my iMac is now almost a full year out of its warranty.
On the other hand, I've held onto this iMac as my main desktop for a long time, much longer than I have for any computer in the past. 3-4 years is a good long time for a mostly-not-upgradeable all-in-one machine so I won't shed too many tears if that problem repeats (although of course I hope it doesn't). You've gotten three years plus out of your iMac, and while it might be tempting to pay for a repair, it might be better to just yank the resellable components (hard drive, RAM, etc.) and purchase a replacement Mac.
If you decide to go for the repair, you might find a sympathetic ear at your local Apple Store, if you come armed with some evidence that this component commonly fails and remain polite but firm. If you're lucky, they'll do the repair at no cost. Hope for the best, but expect nothing.

Apple Cinema Display 22" doesn't power on

All - I have an old 22" Apple Cinema Display, model# M8149 that won't power on at all - no picture, no blinky lights on the front, just totally dead. I've tried it with a known function ADC capable video card as well as a known working DVIator external power supply - notta.
Does anyone have any idea which part may be defective? I see lots of posts about replacing the inverter board, but in all cases, the posts indicate the monitor powers on, just no or blank picture. Mine doesn't show any signs of life whatsoever.
any help is appreciated.
thx,

Are you sure that the connector on your laptop is a "AVG" ? Never heard of that one before. Perhaps it is a VGA???? If it is a VGA and your laptop graphics card is 16 MB video or less, it probably will not support the resolution of the 23 inch. As I can recall, it needs minimum of 32MB video ram to run it. Most older laptops will max out at resolutions of 1200X800. Find out what specs are on the card.

Broken LCD 23" cinema display need your HELP!!!!!!!!!!!!!!!!!

hi can anyone help me im trying to look for replacement LCD for my 23" cinema Display i check ebay none is there a web? i can buy it?

Thats really helpful Dave, well done for going to the effort of making a post which is less than useful.
It may surprise you to learn that not everybody speaks english, and a great many people don't speak perfect english. A purist/elitist would include the entire united states on that list.
If you don't have the capacity to interpret less than perfect english, please feel free to complain to someone else who might actually care about your opinion. I find your post ignorant and intolerant as well as thoughtless.
To provide a slightly more helpful answer to the original question, the LCD panel used in the 23" cinema display is not a common thing to find. Your best bet is to find one with a failed inverter or controller board and swap parts yourself. Apple service providers can only swap out the whole unit for you. Even they are not allowed to order components for these units.

Colored Lines on Cinema Display (30 inch) at start up

Sometimes when I start up my Mac Pro (2012 model) I see colored lines on my Cinema Display (30 inch).
It is gone when I press the start switch again.
What can be the problem?
The Mac Pro has a ATI Radeon HD 5870 1GB Graphics Card.

It is sometimes a sign the inverter cable or board is beginning to go that is used by the LCD.
