My iMac started to show strange horizontal bars (perfectly dividing the screen into 4 areas), with flickering lines. The colors of these bars are blue/black.
Adjusting the brightness cause the bars get less or more visible.
Replaced my HDD with an SSD 6 months ago without issues until now. I was reading about opening the iMac and damaging the LCD display connectors.
The display works perfectly when it’s connected to an external monitor, wired or via airplay.
Did any kind of tests, even Apple Service Diagnostics, no issues found.
