Display keeps tuning off
Hoping someone can assist me with this.
I have a Apple LED 27" display which has been slowly dying. i say slowly because what happens is, while using it for a few minutes, the display just turns off, and i have to unplug the power and plug it back in and then the screen works again.
its important to note that the USB and thunderbolt still works even when the screen turns off.
i have installed all latest firmware updates, and i have even installed a new power motherboard on the device which i got off ebay because someone told me it was power related.
when it first started doing it, it would last almost an hour and then turn off, now its almost a minute and then turns off.
i dont mind replacing the logic board too, although that cost is quite large, i just want an expert opinion before i fork out that kind of cash first whether a new logic board will solve the problem or not.
if anyone knows any fixes i can try, please let me know.
