If "something must have been loose or touching wrong," you had better go in, and take a careful look at all the solder connections, especially the ones you did, to make sure they are good, bright, shiny connections, and not cold solder joints. Also look to make sure that nothing IS touching wrong. If it was a problem before, it is going to rear its ugly head again unless you do.
