First off...
Can you verify your LCD is working?
Even by adjusting contrast to see dark squares, is better than nothing...
Then you must verify your chip is sending data propery...
You can use LED's on the port to make sure your data is being sent. If you send a "1", you had better see the binary "1" with the lit up LED's.
If the above is working, then you must make sure you initialize the LCD before using, and give a "pause" before sending commands to the LCD.
A pause 100 will give the LCD time to wake up.
What does your code look like? (I don't mean just a copy out of the book, but I mean what YOU used to program your pic with.).
