Chosen Solution
So a costumer bring me this iMac A1311 because the device don´t power on. We live in Varadero, Cuba, so the ambiental contamination of the sea its pretty destroying (the salt) rustting almost everything. I clean up the logic board and still wont power on. I need the boardview of the logic board : 820-2494-A, so I could continue to check the device. And if anyone have possible solutions…
@annielservitec you need to know that those are copyrighted and thus we will never post any off this on here. You will have to give us more information so that we can try to assist you with the problem. Number one suspect would be the power supply.
