iMac 21.5" Black Screen Diagnostic LEDs All Green
Hey guys!
Recently bought an imac to repair and flip, just replaced the logic board, but upon turning the machine on and hearing the chime, the screen remains black.
I tried shining my phone on it to see if the blacklight was bad, but no luck. All 4 diagnostic LEDs on the motherboard are green and lit up.
Any ideas?
Is this a good question?
