MKS DLC32 v2.1 problem

Software / Firmware
1

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?

The connection that gives you COM5 is from a USB to UART bridge chip on your board.
I agree you may have a firmware problem.
What happened when it went from working to not working?

Did the wireless stop working for you as well?

What happens when you try to load firmware with the MKS download tool?

I think I did not set the driver voltages correctly, so the drivers got too hot and my laser machine was not working stably. Then the screen came to this state and a warning appeared that there was no connection between the laptop and the card. When I want to connect via Python and mks software, the result is as in the picture.

This is the result I got in python and esptool.

There’s a mismatch in those screenshots where one shows COM5 and one shows COM6. I’d double check in device manager which port is showing up.

One final act of desperation would be to disconnect the TFT, remove the SD card, and pull the drivers out of the board.

Try to use the flash tool with nothing but the MKS power supply and your USB cable plugged in to the board.

If even that fails, you can make one last attempt at flashing with only the USB cable connected- but that would be a long shot.

If all of this fails, the next steps need additional test equipment, and at that point I’d recommend you replace the board.

Some background on this issue:

Actually there is no incompatibility in com ports. I took separate pictures while trying 2 usb ports. So the situation is the same in com5 and com6. As you said, I also tried by removing the drivers, lcd screen and sd card. But the situation did not change. I think a component on the card is broken, for example a small resistor. I will take it to an electronics friend tomorrow, maybe he can detect if there is a problem with the components. But I have accepted that I will not be able to get a result in terms of software.
