Welcome to the forum. Did you read the "How to use this forum" sticky at the the top of this forum section. http://forum.arduino.cc/index.php?topic=149018.0
On of the points talks about how to properly post your code, and another on how to do some research before asking a question. There is a search box at the top right of the forum web page. Try entering "i2c lcd only shows first character on a line" or "led only shows first letter".
It's quite rare that you will be bringing a new issue to the forum, and learning how to phrase your search questions is important.
