Mac cinema display goes black

Before I resolder the backlight connectors and put everything together could you please confirm that these are the ones we are talking about see picture attached. I suppose you were referring to this youtube video where Italian gentleman uses an alternative approach? Yes that is the connector. Make sure not to damage the backlight diffuser if you are not taking out the complete strip.

It will also soak up a lot of heat because of the aluminium backing of the strip. The way back is definitely way harder then disassembling that thing! That plastic bezel that covers lcd and other layers is so hard to put back on and that sugar glass lcd is so freaking fragile that of course it cracked. Luckily I had an imac inch from lying around waiting to be refurbished.

I am testing it now and hopefully it will not randomly switch off till the end of the day. Lesson learned.

I will not attempt to do this again because there is too much risk for me doing that. Probably there is a good technic how to fit that bezel back on but I have not discovered it even after breaking the lcd. It is still doing the same thing with new LCD Can it be power supply or the logic board? All these LCDs have the same problem.

Sure it could be the board but I have not seen that before. Yes that is true. However, I did some testing and thinking. When the display turns black there is no image at all. Not just backlight. The more-common HDMI 1. You can check these standards before buying a monitor. Your Mac hardware also plays a part. The higher-end devices with discrete GPU chips can drive the most pixels, while something like a MacBook would be far less capable, even though they could theoretically connect to the same display with the same cable.

If one monitor displays significantly different colors than the other, you can use color calibration tools to fix the problem. Follow the instructions to create a new calibration from your display.

On your keyboard, locate these keys: P , R , Option and Command. Press and hold the four keys: P , R , Option and Command as soon as you hear the startup chime sound on the Mac, and hold until the sound plays a second time, then release all four simultaneously. Note: you can tell the NVRAM reset is successful by the different volume level of the second startup chime.

Skip to content. This looks more like a possible graphics card problem, in combination with a possible bug there seem to be some problems with people using very high resolutions on their displays lately.

How to Fix iMac Screen Goes Black

May I ask what GPU you're running? I notice that you use the app with floating windows the Mac way. I wonder if a workaround may be to use the Combined workspace - more Windows-like, but some posts I've seen show it to be more compatible with higher resolution monitors and combos. To enable it, Turn on "Application Frame" in the Window menu.

Apple MAC Computers going black screen, out of the blue

I didn't like this method of working at first, but found that once I got used to moving among my items, it was less kludgy than I originally thought. I also have a workspace in which I use my 2nd monitor for most of my panels, and use much more of my main screen for the image, the toolbar and the Options bar. I know that you may not find it ideal, but from some of my reading, it seems to have helped GPU incompatibility bug issues for some other people in other forums I read.

Even on these threads - although, admittedly, most of those problems seem to be occurring on Windows machines with Nvidia cards that need updated drivers. It's very likely that Adobe and Apple didn't communicate well about their driver usage, either. My first thought.

I tried with and without Application Frame. For now I'll just be more careful where I drag the doc window, and hope it is addressed at some point. Thanks for you help. Well, of course the "Staff" person confirmed it IS a bug - hopefully they'll fix it - or work with Apple to fix it. Sorry you're dealing with it. With a nice GPU like that, it should be making you toast and coffee, instead of giving you bugs!
