System not booting, no boot chime, sleep light solid on

Testo:

As the subject says. I can also hear the boot drive make sounds when power button is pressed. Previous threads seemed to indicate that this might be a problem with left I/O board, as previously (when system was still working) I also noticed that USB devices would not power or charge off of the left hand USB connector but would off the right. A replacement (ifixit) I/O board did not change the symptoms. Is it possible that the replacement board is also defective, or is it more likely the logic board is fried?
