Dead iMac, how to do?
I replaced the thermal paste of my iMac as it has been getting very hot lately. Once mounted, the computer no longer turns on: no sound, no fan ... dead. Diagnostic LED # 1 is on, all others are off. I replaced the power supply but nothing has changed. I tried to remove the Ram, the button battery, reset SMC but nothing, it doesn't want to turn on. Logic board dead, CPU dead? How can I understand what's wrong?
Questa è una buona domanda?
