Odds are you were pushing the buttons when gauge was powering up (this does not make it boot up faster) and did this just right to enter the service mode. By then continuing the hit buttons without exiting you turned the contrast off. Here's how to fix it:

LCD CALIBRATION PROCESS


1. Hold left button during splash screens (power up screens)
2. When the screen goes blank. Release theleft button
3. Two numbers will be displayed at the top of the screen. They are rv 32 and rr 26
4. The right button will decrease rv.
5. The left button will increase rr.
6. Streaky displays can be fixed by reducing rv two to three units. Dim or poor contrast can be corrected by adjusting rr. Hold left button down until the contrast looks good.
7. After getting display to the best look. Hold both buttons to write these values to EEPROM
8. Gauge boot-up will then continue normally

The should be no reason for you to enter this service mode unless you've already messed up the contrast. There is nothing you can do in there but mess up things.
