Looks like you fixed everything except the problem!
Have you programmed the PIC?
Are you sure all the wires on your breadboard are all correctly connected?
Is your power supply OK?
Is the +5V present on all the points that require it?
Is your LCD display tested working somewhere else?
These are just some of the things you have to find out before you insert your PIC onto the breadboard.
Post a picture would invite more help...
