blank screen works fine on external only if dp cable is unplugged
symptoms: no image black screen, works on external only if Display port cable is unplugged
diagnostic leds - all on except the last one which is pulsating faintly
problem started after a power failure …
I ruled out most of the parts including screen , cables , powerh source
I have a spare same model with faulty motherboard is there anything else I can try?
it all points to the display-port connector but problem started when Imac was never touched inside still sealed
. any other suggestions ?
