Hat geantwortet auf: Power supply I think?Bad install? Ok, I will contact the supplier and request a return and another power supply to be sent. I will then touch base., here. It gives the LED 1 then flashes all LED 1-4 and completely off, without me pressing a power button or touching the iMac right after plugging into multiple outlets. And pressing the power button does nothing. If I leave it unplugged for a minute and retry, same result. What would be considered a "bad" install @rany ?? Just curious to see what you might know what I might be missing when you say bad install.
