Default ? Voltage Regulator Output Pin Connection

Hi,

I'm repairing my flatbed scanner but I can't figure out what the output pin of
the 7905 connects to.

Here's some snaps:

Reverse: http://img524.imageshack.us/img524/7761/30152421ct5.jpg

I can see where the input voltage and ground pins lead, but the output pin doesn
't seem to lead anywhere. Is it a layered PCB or am I missing something?

It makes sense that the output voltage isn't connected because the scanner does
nothing when plugged in; the power LED doesn't even light.
