MKS DLC32 v2.1 problem

Hello

I think I damaged my MKS DLC32 v2.1 card somehow. There is no image on the screen and I cannot connect. When I connect the card to the computer, it connects as com5 but I cannot upload firmware and I cannot do lightburn. The lights on the card are in their usual colors. Also, there is no burning smell from the card. I tried removing the drivers on it and tried different drivers but it seems not to be related to them. It seems like the software inside is corrupted, I don’t know. What could be the problem?



Does it beep upon power up?

Have you checked that the two ribbon cables aren’t cross connected?

There is no beep. The cables are plugged in correctly. But the lights on the card are on as if there is no problem.

The main controller can be damaged anyhow. The USB controller is a separate chip on the board that might be OK, but that doesn’t mean the ESP32 chip behind it is still operational. I guess it’s toasted.

Thank you.
