2019 iMac 21.5" Black Screen / Loud fan
Any suggestions?
iMac has a black screen. It boots with a chime and I can use it with an external monitor, although the CPU seems to be throttled.
Apple store took a look at it and told me it needs a new screen - expensive. I replaced the screen on my own, but didn't solve the problem. Same symptoms as old screen.
All screen connections appear good.
Any suggestions about what I should try next?
Thanks!!
