Then I would check your contrast....Put a 10k center tap pot with contrast pin of LCD in the middle, and connect the ends of the pot to +/-. ADjust pot until you see black squares...
If you cannot see them with a command 13, then I would start questioning your LCD, whether it is good or not.
When you say "Serial" LCD, you are talking about ONLY 3 wires going to it, right???? 1. - data 2- Positive 3 - ground.
If this is so, you may have to check your manual to the SERIAL LCD, and see how to "Turn it on".
One other point... SCOPE your pic chip!!! make sure you can see your data being sent !
