Blank Screen

I have the, it seems, fairly common issue with my MAKERbuino of the screen having gone blank after a good few days of successful use. It went blank randomly during use one day. The lights come on when the device boots but nothing is shown on it. The device is well-assembled so I don’t think there is any problem relating to soldering etc. Please can you suggest troubleshooting steps.

@mike.egner,

Thank you for supporting MAKERbuino and I am sorry for the problems that you’re having.

When you interrupt the loading process, the console’s memory will be blank so you have to do a hard reset like this:

  1. insert the SD card

  2. turn the console OFF

  3. hold the C button

  4. turn the console ON

  5. release the C button

  6. wait for 30 seconds

The SD card loader menu should appear.

This was also mentioned in build guide’s chapter #4 (under the yellow section marked “IMPORTANT”)

Keep us posted on your progress and don’t worry as we’ll help you make your MAKERbuino work :slight_smile:

I am aware of this procedure and have tried it many times. Nothing happens. Please advise of debugging steps.

@mike.egner,
I am sorry to hear that the hard reset is not working here.

Please try reinserting the SD card a few times in order to clean the dust particles from the SD socket and then doing the hard reset again.

If that doesn’t help, please post a few photos of your console’s front and back side without the casing attached.

Thank you for your patience and understanding :slight_smile:

Hi @albertgajsak. This method worked. For a while it just said “insert SD card and restart” or something like that. But then it came right. I see now that the SD card contacts look very worn or poor quality.

Anyway, maybe I will find the time/motivation to finish the educational notes I started.

@mike.egner,
ok, if you need any further help, feel free to reach out!

Also, I’d love to see your educational notes (finished or unfinished) if you’d love to share them (no pressure)
