Re: iMac 21.5-Inch "Core i5" 2.3 (Mid-2017) 820-01069-b
So I have to report back again that the computer is not working any more. Now it has only led 1 and 2 on. Led 3 flashes and turns off. No chime, screen is black and fan is on. I guess the GPU died and it is integrated on this model. Tried reflowing the CPU/GPU chip with hot air station but there is no change. Just Led 1 and 2 are on....

Re: iMac 21.5-Inch "Core i5" 2.3 (Mid-2017) 820-01069-b
Update: dismantled everything again, cleaned RAM stick contacts with alcohol, checked the voltage on PRAM battery 2.8 Volts so changed it just to be sure. After that it started without RAM sticks. So I asembled everything with current/old RAM and it works. Restarted it a few times and made a power cycle and so far everything works. I still haven't tried unplugging it (the problem occurred last time I unplugged the computer because I wanted to put it in another room). Could it be that the battery made all these problems...

Hi all. In my case with this exact model I get first and third led lights coming up and cycling again only first and third. Second one never comes up and fourth if off because the screen is of. I am thinking it could be bad PSU. Appreciate any suggestions.
