Problem with light fixture

[dfm34]

I have a 2x250w hqi/mh with dual 96w pc actinics (SP) I just changed the pc's (less than a week ago) and they were working fine until last night the rear bulb was out. I check if it was a loos connection but it was fine. The bulb wants to fire up but never lights. Is this a bad bulb or a bad ballast?? Any suggestions on what it could be or how to fix?

Thanks in advance

If you have your old bulb you took out put that in and see if it works

what do you mean by the bulb wants to fire up? I assume you are talking about the pc's

When the PC fixture is turned on the base of the bulb flashes but never completely lights up. Last night I put my old bulb back and it lite right up. SO I assume it is a problem with the new bulb
