21.5" iMac screen displays a very faint Apple Logo after hd swap
I replaced the hard drive in my late 2015 iMac 21.5” Per the iFixit instructions, I tested the unit before permanently sealing the screen to its back.
The screen does not display anything EXCEPT for a very faint pulsating Apple logo. My local uBreakiFix store got the same pulsating logo using a different monitor but could go no further. Reinstalling the old hard drive resulted in the same results.
Any ideas?
Thanks in advance.

Is this a good question?
