I bought a Late 2015 27 inch 5K iMac without an HDD. At this stage, I was able to make an external SSD boot disk and it's working (externally). My plan is to install it inside later. But, as you can see in the pictures, it has some periodic lights on and off at the bottom edge of the screen, all the time. I'm new to Mac by the way. My understanding that this could be due to the LED strip(s)/bulbs or maybe the cable or maybe the board?. There is practically nothing online for videos on this matter and model that shows clearly what's happening.
I'm not even sure if it takes 1 or 2 LED strips? what part numbers?
The cable that powers the LED strip splits into two sides, right and left. I'm thinking it could be something due to the cable or the signal/electronics, because the stage lights are symmetric all along the edge and not shining in one side of the screen, the fault could be coming through both sides of the cable, it could originate from the root cable or before that ?!
Anyway, any more resources please? I can't even confirm the parts.
