My iMac wont start after ssd upgrade. 1 LED, momentary 2nd LED
So I took on the task of upgrading my HDD to a Samsung 850 1TB EVO. I had done this to my Macbook pro and worked amazing and decided to do it on my iMac.
Everything went smooth as far as the installation. Upon pressing the power button, the unit does not turn on. You can hear the fans intermittently turning on and off. Nothing happens after that, just a continuous attempt to power up.
So I took off LCD again, there are 4 LED's on the board, 1 lights up solid, #2 lights up about every 3-4 seconds, at the same time of the LED turning on a for a sec, the fans turn on, when light turns back off, the fans turn off. Again talking about the 2nd LED, thats basically where it stops.
I am at a loss, apple just wants me to bring it in, but I feel its something simple or something I can replace. Any help would be great!
Talking to Apple, they mentioned it's not likely its the power supply, but COULD be...
Is this a good question?
