Yep - actually, theoretically a fluorescent tube doesn't have
resistance (more than a piece of wire has), it just causes some voltage
drop. So virtually, the ballast should survive from driving as shorted
as well...
For OP: It isn't virtually possible. Of course it is, but it's very
unlikely - just like the Don said (ballast damage). When a tube is
burned out, just replace it and try, if it starts, it's ok, if not,
replace the starter, then it should be ok :-)
