TTG Screen Board LED Indicators

X5 Base Board 

  1. Power supply LED indicators. If all power supplies for different voltages are properly powered all LEDs should indicate that when they are on. If one or more LEDs in this section are missing this is an indication that something is wrong with the power supply.
  2. Blue/White LEDs: They are only on if the TTG cannot boot. This can happen if:
    1. No SD card is present
    2. No proper formatted SD card is inserted (wrong image, format, etc.)
    3. The SD card is malformatted 

If everything is ok the LED pattern should look like this:

X5 Top board(s)

Every X5 top board should have a single green LED which indicates if it is powered correctly.
