Sorry this post got way long, hopefully not too much info to get some advice. I didn't know what to edit out. I'd love to find a DIY fix for this problem and feel sure its the power source thats the issue, not the display picture.
2009 MacPro 2 x 2.26 Ghz Quad core Intel Xeon / 32 GB memory silver tower (Model No.A1289). [link|https://everymac.com/monitors/apple/studio_cinema/specs/apple_cinema_display_30.html|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!

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.

Winter is full on here; my pipes froze & I'm still in the throes of crawlspace work so may not be as responsive as usual. And if I disappear for any length of time, the electricity has likely gone out - but I'll be back =0) Thanks for trying to help me!

Experimenting, I found the oval/racetrack-shaped plug connection (don’t know the proper term) in the “Dual-link DVI” adapter brick (Apple HD Display 150W Power Adapter A1098, connects to the MacPro) may be the problem, because unplugging and replugging it fixes the issue temporarily.

- Shopped around for other 30” monitors, like this [link|https://www.walmart.com/ip/Dell-UltraSharp-U3014-30-Class-WQXGA-LCD-Monitor-16-10/33043751|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
Sorry this post got way long, hopefully not too much info to get some advice. I didn't know what to edit out. I'd love to find a DIY fix for this problem and feel sure its the power source thats the issue, not the monitor itself.
2009 MacPro 2 x 2.26 Ghz Quad core Intel Xeon / 32 GB memory silver tower (Model No.A1289). [link|https://everymac.com/monitors/apple/studio_cinema/specs/apple_cinema_display_30.html|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 “Dual-link DVI” adapter brick (Apple HD Display 150W Power Adapter A1098, connects to the MacPro) 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?). [br]

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

***Can I replace it myself without much tech experience?*** Viewed a Youtube video [link|https://www.youtube.com/watch?v=fidZNrjHwfU|Apple Cinema Display - Teardown and Repair] - a cord replacement guide for a 27” thunderbolt Cinema Display, and think I could manage that much, but mine isnt a TB display.

***Can I replace it myself without much tech experience?*** Checked [link|https://www.ifixit.com/Teardown/Apple+Cinema+HD+Display+30-Inch+Teardown/126212|this ifixit guide] and viewed this [link|https://www.youtube.com/watch?v=fidZNrjHwfU|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
