Can logic board of 2009 iMac to be used in 2010 iMac, both 21.5"?
I have a mid 2010 iMac, 21.5”, A1311, can’t startup at all, no chime tone, black screen, but fan running ok. I have checked the power unit, it works, so suspect either GPU or logic board may be broken.
There are many forums on how to replace/upgrade GPU for old iMac, and how to choose right GPUs, but there were few sharing on how to choose right logic boards, so like to hear from you guys on how to choose and identify right logic boards to fix broken iMac.
For instance, it is possible that the logic board of 2009 iMac cab be used for replacing logic board of 2010 iMac, both 21.5"? Any official sites to find out how to identify logic boards for iMac? If two iMac have same model no., say, A1311, can their logic boards can be used for two machines ?
Thanks for sharing
