newbie lighting/ballast question

[caricell]

Hi!
I have a Coralife Aqualight 48" deluxe 4x65w 6700K fixture on my 55 gallon FW tank.
As of yesterday, 3 of the 4 bulbs wouldn't light up.
I took the "known good" bulb and tried it in each of the sockets and it works fine.
Does this mean that the other 3 bulbs are no good, or could there be a ballast problem?
1) What do you think
2) How, exactly would I get into this fixture to replace the ballast if a I need to? Do I remove the screws on the reflector part, or on the two side panels of the fixture? And then what?
Any assistance is MOST appreciated.!
Thanks!
Larry

I would suggest buying at least one more new bulb and trying that out. It sounds like you have a bulb problem. I have a coralife light w/4 65watt bulbs 2 day 10000k and 2 actinic, and I have had bulbs just randomly go out. So before you tear your light apart buy a new bulb first. thats IMO though.

Thanks...I think you got it right. I got 4 new bulbs today and put them in and they all work. ONE problem though...
When taking one of the bulbs out to reseat it, one of the little pins inside the socket (endcap)? flew out and across the room. Needless to say, I cant get that bulb to light now because of non-contact.
Do you know where I can get a new pre-wired socket that I can just splice in?
Thanks in advance!
