Black screen after hard drive replacement
Hi,
I replaced the HHD to an SDD following the instructions on ifixit. Before gluing the screen with new stripes, I tested the devices by turning it on. Everything worked and I was able to re-install the macOS. So far so good.
Next, I used the stripes to finalize the process. It seems, that something got wrong during that step: my screen is black now.
So, I re-opened the iMac again and checked, whether I forgot to connect a cable or damaged anything in course of the process. Didn‘t find any hints, though.
Next, I connected the two cables, put the display back (w/o the stripes) and started the device. I am able to see some content on the screen, but it‘s very dark.
=> My assumption is, that the backlight is not working. Maybe I damaged the cable or even more. Would you agree?
I would like to start with replacing the cable. Question: which one (of the two)?
Thanks in advance.
