Help Repairing My Aquarium Light

[Eb0la11]

Hey guys,

my FW tank aquarium light seems to have finally quit working. I'm not sure what is wrong. I have changed the bulb to a new one and it still is not working so it's not the bulb.

It's a very simple 40W FW 4 foot lighting unit.

I've taken it apart and took a couple shots of the interior components tucked behind the reflector, they are below.

What component do you think may no longer be working?
Where in Calgary can I take it to be repaired or buy the necessary parts?
