Hello! Has anyone encountered problems on the Imac 2020 27 inches with a T2 chip? I had to replace 2 T2 chips on two iMacs, the first one was successfully replaced, tested and given to the client. The second iMac after replacing the T2 is flashed, the system is installed through the target mod, it boots into the system, you can hear me tapping on the keyboard, but the image does not display (and to an external monitor). I reballed the T2 chip, changed the processor, RAM, display. No positive result! My friend said that he had 2 such devices and on both of them, after replacing the T2 boards, they either did not boot into the system or showed artifacts.Maybe this board has a factory defect? Who has encountered this?
