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

    Hello,

     

    Your trouble is not listed as a known issue, so I would try the following:

    1) visually checking the board (all components placed according to design files, no misplaced components, scratches, integrity of connectors...). (I assume you don't own of know anyone with an x-ray to check the BGA soldering.)

    2) check temperature of the components to rule out overheating

    3) use another sufficient and stable power supply

    4) use less and / or different peripherals (or try a powered USB hub).

     

    If none of this works, I would request an RMA.

    Hello

     

    Thank you very much for the reply. I checked all your recommendations. The only one that stands out is the peripherals. When I only connected the HDMI cable the BBB stayed on. When I restarted with the Keyboard and Mouse Connected to a USB Hub that is when the BBB screen shut off.

     

    An interesting observation though is when I connected that same peripherals and the same power supply to a BBB REVB with the 2GB eMMC the screen stayed on. It was running Debian though so I don't know if that is a factor. I have another REVC that I will reinstall Debian on and see if I have the same issue.
