I suggest adding a few lines to your program so it still goes through the
motions of reading the LM75, but then forces the result to be a known
test value before displaying.  This test will tell if you're having a
problem with reading or with displaying.  If it seems to work, replace
the test instructions with nops so the timing is exactly the same.  If
that works, then the problem was timing.
