Did you set the correct fuse settings before uploading the code ???

It is assumed here, that

This is tough project for a first timer to get a LCD going on.  I know this from personal experience.   There are so many things that can prevent a successful project.   First did you get confirmation that the IC was successfully loaded with code?   What hardware did you use to program?   Are your wires connected correctly, do you have any bad traces or shorts, did you adjust the pots for the lcd display(and check voltages) .......and so forth.  The fact that you have nothing showing seems to indicate there is a problem with the IC or connections, because when the program first loads there are some text that should show up.  The first step is to get something to show up on the lcd even if it's crazy characters.
