Imac 20 a1224 repair
Hello, i have Imac 20 a1224. And when I turn it on, 1 diagnostic LED is constantly on, and 2 and 3 light up for 5 seconds and go out instantly. 4 LEDs off. I checked the surge voltage on the power supply, it matches the information on the network. Can anyone help in diagnosing the logic board? The components look intact, the capacitors are okay. I still don't really understand what chips and how to check when I look at the schematics. -
Imac a1224 logic board boardview search
Hi I have a faulty imac a1224. When turned on, 1 LED is constantly on, and also 2 and 3 diagnostic LEDs light up every 5 seconds, and then they immediately go out. I checked the voltages of the power supply when trying to start and they correspond to the declared. I think the fault is somewhere on the motherboard, but I can't find boardview for this model on the forum. Only .sch, no .brd. Can someone share? Thanks -

Hello from Russia! I'm just a guy who takes care of forgotten and unnecessary computers. I have accumulated several faulty machines over which I am now thinking. I hope that someone will prompt me in some questions, and also I will be able to help someone.
