Problems after replacing PSU
My EMC 2390 (mid-2010 27”) iMac had a dead PSU. After replacing the PSU with one from iFixit, firstly the fans go crazy (I know have to use Macs Fan Control which I didn’t before) but most annoyingly the iMac’s display blacks out, then the iMac goes to sleep, after about 30 seconds. I read a comment from another poster who had the exact same issue and advised resetting the NVRAM on boot - this works for me as well, but like that poster I have to do it every time I boot or else the problem reoccurs. I’ve tried resetting SMC also with no improvement.
I am thinking it’s something wrong with the iFixit PSU, but not sure. Would appreciate any guidance!
