Anyone have advice on troubleshooting a apple model a2m6021? Got no power, I haven't found schematic so obviously prior knowlege will be important. But before the easy electrical stuff I have a physical issue that I can't figure out... it appears the back panel isn't separating from the case when opening it up, is that correct? Shouldn't that powre/control panel stay with the frame not the case?
EDIT, I decieded to see if it was just friction and carful pressure I was able to get the case free of the panel and it's open now. Basic check and all fuses I could find are good. I don't see any obvious damage, everthing looks brand new there's not even much dust inside. I'll start probing the board but if anyone has a squence for this system tthat would be helpful.
