Hi guys, suddenly display stopped work, it won't show anything just black squared symbols. Any ideas?

Thanks in advance

Hi


I suggest you check the electrical connections.
You can disconnect all wires of the LDC module and reconnect them.

Hello, I tried but didn't work. I guess is more a software problem instead than cables. Thanks!

Exactly.
If you are sure that the connections are working, you can try to upload the firmware again.

Hello, thanks again.
Yes, that's what I would like to do, the only problem is that I don't know how to do. I'm very beginner....Do you have the possibility to help me or to send me some links where I can learn the firmware upload procedure?

In the first step you need to identify the model of your controller board. That's the basis.
The next step is to acquire theoretical knowledge.
Then you will need a firmware file.
Depending on the version of the controller board, there are two ways to proceed.


Try reading the topics here and here.

Once you have gained some knowledge, questions will surely arise.
But you will be able to ask them precisely.

thanks a lot. god bless you!

Hello, my board is GT 2560, do you know which firmware should I get?
Thanks

Hi


You still know too little.
You know the model, now discover the version.
