As some have mentioned, it's fairly common for these to fail, sometimes rather spectacularly. As long as the replacements are X2 rated, of equal or greater voltage rating, and similar capacitance they will work. You don't need to find exact replacements although it's nice when you do.
As a temporary test it's fine to remove them. It will likely cause interference on nearby AM radios but few people listen to AM radio anymore anyway.
