The labeling might be different, but that does look like the schematic. No worries there. The extra components you mapped are because +5 is connected to everything. But now that we have all components labeled according to the XEGS, could you take a resistance reading from R72 on the crystal side and ground? If it's close to zero, you have a short to fix. If it's closer to 470, then Q6 is dead. If it's significantly higher than that, then I guess it might be okay, but with the voltage readings you took, it wouldn't make sense.
If it turns out you have a short, check C53. Also look for small objects in the area that don't belong and might be fusing connections.
