Sorry, not the resistor fix, you need the controller transistors to be intact. They're near the trim line, did you hit them at all?

Thank you, I will follow your advice. This is that set of transistors. If it doesn't work, I'll take it from another board and put it on.

The relocation vias for the transistors are marked in the trimming guide btw

Thank you very much for your help. Now that I can use the control unit, I fixed it by supplying 3.3 volts through a 750 ohm resistor. before entering the data line of the control unit according to the position in the figure
