I opened my 2019 27 inch IMac to fix a drive problem. Fixed problem, reattached display. Now screen is very dim. Can see the apple when it comes on, but it is very dim. First time I reassembled, I couldn’t see anything and the fan motor was racing. Checked and reattached connectors again, now display is dim, but fans are not racing. Does anyone have an idea what it could be?
Thank you!
