1.Refering to wiki, please check all the pins are connected correctly.
2. Do not use USB port on Arduino board to give power. The reason that screen has lines and dots is because the voltage from USB is not high enough. You can use 9V battery to provide power for Arduino.
3. The voltage of TFT is 3.3V.
