Josh,
I'd first try lifting one side of CR22 and see if your +5 returns.
If not, you can remove IC 63 (probably what, a 7805?) and see you can
read anything at the high side of C67. You should be able to--unless
you've got a bad diode.
If the CR22 maneuver doesn't result in any improvement, then you've
probably got a fault somewhere else on the board. Make a quick
resistance check while you have IC 63 out with the power off, checking
the resistance between the +5 lead and ground.
That should get you started on where to look.
