I honestly do not think so. But if you're really worried about it, and if you have a lot of free time, and if you don't mind the extra effort involved, you could swap CRTs and check to make sure that your CRT is okay. Then once you confirm that it is okay, you can swap out your analog board. Then again, if you swap out your CRT and confirm that it's okay, there's really no need to swap and test your analog board, since that's really the only thing left that could be broken.
