New Brain with blank screen

We purchased the 12 kit bundle and one of the brains screen lights up but nothing shows up on the screen.If I hold the “X” button the machine turns off it appears but there is still nothing on the screen to show this. Firmware has been updated. What is there I can do?

Hi brmstsa,

We are sorry that you are encountering this issue. It seems that there may have been a problem during the Robot Brain firmware update process.

To correct this problem, please turn off the Robot Brain. Press and hold both of the arrow buttons (Up and Down) while you press the Check button to turn on the Robot Brain. The Robot Brain will now boot into manual DFU (Device Firmware Update) mode. The Robot Brain LCD Screen should display the following text:

VEX Robotics Inc. DFU

 Connect to PC for
  Program Update

                 V1.01

If you see this screen, connect your Robot Brain to your computer and run the VEX IQ Firmware Update Utility again to re-install the Robot Brain firmware.

If you have any problems or do not see any text displayed with you boot the Robot Brain into DFU mode, please contact VEX Technical Support at [email protected] or call +1-903-453-0802.

Regards,
