I have an imac 27 "core i5 of 2011 Model A1312 (EMC 2429), I recently started with a black screen while I'm working. The computer is still operating, but I can't see anything. I stop using it until it stops due to inactivity, I press a key and the black screen It disappears and I see the desk with the task I was doing. After a few minutes the black screen returns.
Any solution?
Thanks in advance for the possible help.
Please attempt resetting the NVRAM and also restarting in Safe Mode first to see if either addresses the problem. Can you tell us which GPU your computer has?

Hello rkaufmann87,
I have already done the mentioned steps and everything remains the same.
I will try to connect a second monitor to the video output.
With the TeamViewer app I can control and turn off the imac when the black screen is on.
The your display or the backlighting has failed which means it's hardware and there is nothing a forum can do to help you fix it. You can take it to an Apple Authorized Service Provider to see if they can fix it.
Yes 8 years. For these lands we use the mac to exceed the limit. It is not easy to update the models constantly. They arrive in Argentina and very high taxes are applied, the mac are considered exotic and expensive products, unfortunately.
I have been an Apple user since 1986, more than 30 years with the brand.
Returning to the problem: the solution was to buy a monitor (LG with hdmi input) and connect it to the displayport with an adapter for hdmi.
In the system preferences set the second monitor as the main one.
I am working and there are no blackout problems or black screen on the new monitor.
Thank you, I consulted the official support (Argentina) and the answer was: it is a discontinued model and they cannot help me.
Well it's 8 years old, you can take it to another AASP and get a second opinion or you can buy a new computer.
