A10M Blank screen after startup

[cDuck28Z]

Good afternoon. I've been searching around the forums and found some posts about the A10 and A10M screen being completely blank, or having nothing but black boxes instead of text. My problem is slightly different however. The machine boots up perfectly fine, and i can see the Marlin logo and read the Marlin version text. After that however, the screen goes blank (still backlit) with no text on it. I've tried reflashing my firmware to the version that I have been using for quite some time now, but after compiling and uploading, I get the error "An error occurred while uploading the sketch" with no other amplifying information.

Stranger yet, this happened randomly with no change to my machine. I tried turning it off and back on again and it actually worked until I got through about 1/2 of a short print. The machine power cycled, then the message on the screen read something like "print interupted, please restart" or something along those lines. Once I powered it off, the machine has not displayed any text (except for the startup logo and text as mentioned above) ever since.

I pulled the cover plate off to reveal my board and noticed a flashing orange light labeled "L". I don't have a ton of experience or memory looking at this board with its cover off, but I don't recall seeing any flashing lights from down there.

Thank you for your help in advance

If anyone ever has this problem in the future, TL;DR it was a corrupt SD Card.

I took disconnected every single cable and wire from my motherboard one at a time with no success. I tried updating my firmware with my previous version but could not get arduino to transfer the successful compiled code with spitting out an error. But simply turning my machine off, removing the card, and turning it back on seemed to fix the problem. I originally thought the problem was that my card was full, so I cleared the card but did not reformat it. This did not solve the problem. As soon as I plugged the card in, the screen would not boot up with the machine. I'm running my first test print now with a new SD card and everything seems fine so far. I will keep you all updated if this indeed was not the solution to this issue.

Habe das gleiche Problem wie du. Nach dem start ist der Bildschirm nur hell mit zwei Zeilenbalken. Die gelbe Lampe Blinkte auch anfangs, jetzt nicht mehr. Zusätzlich kann ich auch keinen PC anschliessen um ggf. Firmweare neu zu laden. Wenn du eine Lösung hast bitte melden.

For me it was a corrupt SD Card that was the main problem. A brand new SD Card fixed this problem entirely

Für mich war eine beschädigte SD-Karte das Hauptproblem. Eine brandneue SD-Karte hat dieses Problem vollständig behoben
