iMac startup but nothing on the display...
I’ve got an iMac 21,5” from Early 2013.
When I press the power button, I can hear the fan spinning and I hear the startup chime, but it doesn’t show anything on the screen.
I’ve tested it and the display panel is good, this isn’t something that’s wrong with the software and it can’t be the GPU because I’ve replaced the CPU (it only has integrated graphics) and it still doesn’t display anything… It’s not the RAM, the disk drive, the display nor the power supply.
The fan doesn’t speed up to the max and the only LED’s on the Logic Board that are on are the lower two LED’s.
I’m kind of getting lost with this iMac… I hope someone is able to help or has some advise…
