We need more information.

1) Post the SHORTEST possible version of you code.
2) Advise compiler version, LCD type.
3) Read forum guidelines.
4) Follow forum guidelines.
5) Search forum for help.
6) Double check connections.
7) Check connections again.
8) Check bias supply.

You're not the first to have LCD problems.

...won't be the last either...

we also need to know the PIC used and the pinouts...

and of course, this is a REAL situation and NOT a 'simulation...
