iMac mid 2011 black screen on boot
I opened up my iMac mid 2011 21.5 to change the HDD to an SSD.
Now all I get is a black screen after chime on boot. I’ve tried resetting PRAM, ensuring all 4 cables are seated correctly (the LVDS connection is a bit loose but is in), all 4 diagnostics LEDs come on and stay on.
I changed back to the original HDD, I’ve cleaned all the dust out…but still no luck.
Anybody got any other ideas? Thanks
Oh, and I can’t see any icons when shining a torch on the screen.
Is this a good question?
