iMac won't start after installing SSD and dust cleaning
Have SSD installed on my iMac and did dust cleaning, however, after putting everything back, it won’t start, here is what I found:
- Get the display unconnected.
- Connect the power cable, LED 1 lights up.
- Press power button, LED 2 lights up very shortly, then lights off quickly, 2 seconds later, LED2 lights up again, but off quickly, it then goes into this loop.
- I can see fans are spinning for a short of time when lED 2 lights up, but stop spinning when LED2 goes off.
I double checked everything, can’t see any cable connected wrongly.
Does anyone know what could be wrong here?
