Solved Imac Won T Start After Hdd Replacement No Chime Black Screen Dvd Imac Intel 20 Emc 2133 And 2210
Chosen Solution I don’t know if you were able to fix the display issue or not but I ran into a similar problem as you with only 3 LEDs lighting up on boot, after I upgraded the processor, airport extreme card and swapped the HDD for an SSD. I also thought that I might have broken the LCD connectors or might have done something to damage the logic board but that did not turn out to be the issue....
