I believe to have all connections correct from the launchpad to my breadboard, but when I connect VCC to my board the LCD just flickers some vertical lines and then the LCD goes dark again. Anyone have an suggestions?

05 - R/W GND
06 - EN Pin9 (P2.1)
07 - DB0 GND
08 - DB1 GND
09 - DB2 GND
10 - DB3 GND
11 - DB4 Pin10 (P2.2)
12 - DB5 Pin11 (P2.3)
13 - DB6 Pin12 (P2.4)
14 - DB7 Pin13 (P2.5)
15 - BL+ +5V
16 - BL- GND

// include the library code:
#include <LiquidCrystal.h>
// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(P2_0, P2_1, P2_2, P2_3, P2_4, P2_5);
void setup() {
// set up the LCD's number of columns and rows:
lcd.begin(16, 2);
// Print a message to the LCD.
lcd.print("hello, world!");
analogReference(DEFAULT);
}
void loop() {
// set the cursor to column 0, line 1
// (note: line 1 is the second row, since counting begins with 0):
lcd.setCursor(0, 1);
// print the number of seconds since reset:
lcd.print(millis()/1000);
