Double and triple check your work. Make sure all the parts you replaced are properly replaced, wired where they should be, and no cold solder joints. I have screwed up before; I think we all do eventually; so double checking to make sure each component was replaced correctly is where I would start. Once I was certain about that, I would then do the alignment. I would do it again whether or not I found any mistakes I had made before.
