Logic Board Replacement Gone Wrong
Howdy. Help, please? Thanks. The short tale: bad spill damage. Corrupted logic board, but only partially. No local video, fried ethernet port. Everything else, including external video, survived. The replacement cost quoted me by the local non-Apple, Mac shop was more than I could justify on a year and 1/2 old machine. I'm handy so off to iFixit I went where a kind gent linked me to an inexpensive ($500) replacement out of Shenzen City. I have it, installed it but get nothing but the chassis power/status light when I boot up. SO, the first question I'm hoping the hive mind can educate me on is: post-logic board swap with everything healthy and in it's proper place, should the computer start up "normally" without any other software/format
Generally yes replacing a logic board will repair a liquid spill, unless the spill damaged other components like dc in, wireless, hds, optical drives, RAM. If HD was not damaged you should be good to boot the machine... try a safe (shift-) boot just to ensure that there's no unusual startup files hanging you. Try a Single User mode start by holding Command-S during startup. If that doesn't fly you could have other problems.
