Beaglebone Black Rev C screens shuts off

ruanknoetze

I recently bought a new Beaglebone Black rev C and started playing around with it by using a standalone setup with HDMI, keyboard and mouse. After a few minutes the screens completely shuts off and does not want to start up again. I thought it might be a OS issue and re flashed my eMMC with an Angstom distribution. After start up it did the exact same thing. I even added code that disables the auto sleep mode of the screen but that does not work.

 

I know the BBB is getting input from my mouse and keyboard because one of the LEDs flashes when I type or click.

 

Has anyone ever experienced this and what can you recommend I do?

 

Thank you

    Hi All,

     

    I got one BealgleBone Black a few days ago and connected its HDMI port to the monitor through the VGA splitter. I flashed it with the debian IOT version. It came up and a few minutes later, it turned off. I wriggled the cable, then it came up again, and turned off again after a few minutes. I returned for another BeagleBone Black, and now I got the same thing.

    Note that I already had two BeagleBone Black Wireless boards, and both works all the time, no problem with HDMI. In theory, there is not much change between BeagleBone Black and the Wireless version. Has any body have a reliable working BeagleBone Black bougth recently?? If yes, let us know where you bought it.

     

    Regards,

    Henry
