820-3023 mouse is on and off


New member
Recived this macbook. Board: 820-3023
When I press power no video, but I can see how mouse light up for 2 seg and off and on and off again and so on. I check the board and found cracked ram. Could be that the problem?

Ram is written: J2108BCSE-DJ-F

Also I cannot find where to buy this ram. All board from aliexpress comes without ram chips. Any idea?


Cracked RAM will not let the board boot. You have to wonder how it got cracked though, was this dropped?
J2108BCSE-DJ-F is on Aliexpress.
