Replaced the Logic Board and the left i/o board - now what?
No startup chime, no video, solid sleep LED, optical drive makes noise, and after staying on for a while, the part underneath the F keys gets hot.
I had a question about this same problem, and it was suggested the i/o board may have been the culprit, so I replaced it. Both the LB and the i/o board were brand new - not used or refurbished.
I followed the instructions here to the T, but I am just lost - I don't have the knowledge to know what to look for or troubleshoot beyond the obvious things I've read about.
Could it be bad wires? connectors? if my Fans were not working, could it cause the MBP to fail the POST?
