A common failure on this model is the fuse blowing.. measure +5 to GND for resistance, if there is none it is a blown fuse, fix it accordingly :-)
Yep, Just use the X-ray machine and Lazer you have laying around...
If you know the location of the uncovered V+ pad (B), then measure its resistance to the corresponding pin (A) of the edge connector. No need for a laser.
However, before bridging the fuse (F), I would first confirm that there is no excessively low resistance between V+ and ground.
Code:

The above diagram is for a USB flash drive, but the principle is the same.
BTW, have people never heard of cropping their images?
