I just upgraded my late 2015 imac’s cpu to an intel core i7 6700k skylake unlocked 4.0Ghz processor and when i tried to turn it on after, i got the chime that it turned on, but the screen will not turn on . I checked the connections and they’re all good, so i have no idea what it could be . Anyone have an idea? Thanks
Did you fix it? Are the led’s on the LB on?
