No Display back light only - can't see icons wont display externally
Does anyone know if the GPU is upgradeable or replaceable? on the iFixit teardown, I cannot see where the GPU is on the logic board or whether it’s a replaceable part?
The issue is Currently, the iMac turns on and chimes and but no display, just backlight glow and can’t see any icons using a torch. It also won’t display externally using an external display port.
