Dropped Arri 300w now different color temp?

So my Arri 300w fell over on a shoot (ouch) there is no physical damage but now it displays a warmer color temp than 3200k and it appears to be a bit dimmer. I replaced the bulb but still the problem persists. I opened it up and everything looks fine but then again I know little to nothing about the construction of these lights. Any ideas on how to fix this? think I might have to send it in?
 
It sounds to me like an electrical issue. It should be easy enough to fix, but I'd make sure someone with experience rewiring tungsten lights does the job.

There's no active components in a tungsten fresnel other than the bulb. It's hard to imagine how the wiring could be loose and still allow the fresnel to light. There should be a terminal block in there where the line voltage wire coming in connects to some wires which go to the socket. To my knowledge there shouldn't be a fuse in an Arri fresnel so its pretty much a straight connection. Check to make sure all these wires are still tightly connected.

The other problem that comes to mind is that the bulb is usually centered pretty well in the mirror behind it. If something in there was knocked around, I suppose that the bulb could be a bit off center, thus giving a less than optimum light output. I rate that as the most likely culprit if you replaced the bulb and it still seems to be dim or too warm.
