You’ll need to closely inspect the area around the Tristar IC to insure you haven’t caused any damage to the surrounding components. Also, if you remove Tristar again, check the condition of the pads to insure there is no physical damage. If that looks good, then start probing the main voltages to insure there aren’t any shorts that were caused by your work.
