Metal Halide and HPS bulbs both require a few minutes after shutdown to power back up. I think MH takes longer (about 8 minutes). This doesn't sound like your problem, though. You say your bulb "blew." Did it just stop working, or did it actually blow up?
Something to try:
Plug the ballast into a different socket (you may have blown a fuse), or try plugging something else into where the ballast is plugged in.
A lot of these digital ballast are pointless to open and inspect as the components aren't really accessible once inside. Your wire leading from the ballast to the lamp is accessible, though. Unplug the ballast and see if you can't inspect the wire running to the light socket. Also, check for burn marks from arcing. Check at the point the light screws into the socket, and if possible, check where the wire goes into the socket (from the ballast).
Having some problems with my own at the moment (turns on and off for no evident reason), so I'm interested in what is up with yours. Hope this helps a bit.
Superb mate, as you suggested here:

Just did that mate and it sorted my shit out... It was my shade/wiring not ballast
I've had one of my 600w out for a while in my 2 light tent and have tried 4 more maxibright digis to no avail, they all repeatedly fused my leccy.
It's been really frustrating.
I was well disappointed and thought how shit for all my digis to die as there's only a few years old with low use.
I was gonna buy a new one tomorrow but thought it's worth googling maxibright 600 w won't start and find this thread.
