2012? Imac starts up fine, after a bit of time the screen goes black, walk away, come back, all is normal again. Repeat...
Did a Nvram reset with up to 4 startup sounds.
The fan does not make noise!
Could it be because the fan does not work?😱
can the fan be replaced? 😌
thanks much for any help or pointers to help🥴

Likely a hardware problem, please take the computer to your local Apple Authorized Service Provider to have it diagnosed. Then you can decide what to do.

Thanks for your answer, I will consider this after some more research.
The computer is already on it's last legs, because the OS cannot be updated beyond MacOS High Sierra Very 10:13, a fact that reminds me of my Microsoft days. Alas
Thanks again and stay safe.
Your welcome and good luck. My guess is it may be a failing backlight or failing display. If it is a backlight these are not too bad to repair assuming you can find the part on pre 2011 iMacs.
