Sean Chan has determined that since all his lenses refuse to reach
infinity, and close-ups are misfocused, there must be something wrong
with the camera.

One obvious possibility is that the mirror isn't coming all the way
down. There's a tiny pin on the side of the mirror chamber that the
mirror rests against. If you lift the mirror and let it fall back, you
should be able to tell whether the mirror touches the pin when the
mirror is down. (If you can push the mirror farther down, it obviously
isn't resting on the stop.)

Another possibility is that the focusing screen is not in the right
plane. Remove the screen and look to see if there's any dirt on the
screen or frame that might keep the screen from sitting flush. When you
reinsert the screen, check that it's aligned correctly and frame closes
"flush" over the screen.

The only remaining obvious thing is that the camera is grossly
misassembled. This is hardly likely, since this sample presumably worked
correctly before.
