Old Apple LED cinema display problems

[_thomas]

I have a 2011 (ish) Apple LED Cinema Display 27". TO be clear, it's the MDP model, not thunderbolt. Recently it's developed this behaviour where it's screen will go black whilst in use. It's always still dectected as a display and it's speakers etc stil work whilst whatever desktop I have extended or duplicated there remains running. 

 

To get it working I can unplug it from power and then plug it back in again, a few times, and then it'll work constantly (hours and hours) until I power down whatever machine I have it hooked up to. 

 

IS this a common issue and is there a home spun fix for this? Feels like it could be a power issue but perhaps limited only to the display?

 

For context it behaves the same way when using any machine plugged into it - currently it is regulary used with a 2010 macbook, a 2014 macbook pro 15" and a couple of Lenovo laptop (a newish thinkpad and an ultrabook).

 

Any ideas?

Sounds like either a bad display cable or a dying display panel to me. You should first try a new or different display cable and see if the issue still persists, if it does then it's either the port or the display panel itself my guess is the panel. You can maybe find a replacement panel for it, but with the age and the probable cost of that kind of part (Apple parts if rare or in high enough demand will be expensive even if they're that old), depending on the price of a new panel you may just want to look into getting a new monitor entirely.
