This sounds like a lot of problems which I wouldn't start to troubleshoot, basically there are issues with Y and the 3DTouch. You could check the 3DTouch wiring, but that doesn't fix the Y problem. I'd replace the board and buy a real BLTouch. There might be things broken beyond fixing. What makes it difficult that this printer also has a custom screen with its own firmware, it might be difficult for someone without much experience to solve this.

Thank you for the reply @0scar. I don't have much hope for the board as you mention. Can I ask you some rookie question? I feel like drivers and cpu heats up so quickly when i start to move axises. Cpu heats up even on idle 70 80 degree Celsius if i guess. Hard to touch. Drivers are tmc2209 by the way. Not sure what mode. I examine drivers they were heat up before printer broke never check cpu before incident. Do you think these are normal?

I believe the max temperature of the TMC2209 is 125 ºC. The printer uses the MKS Robin Nano board V1.2.

This is a brand new Two Trees Bluer Plus 3D printer. Default, it has a 3DTouch probe installed.

Printer is broken now, I couldn't use it even for a week...
In middle of a long print, our home fuse blew. I am not sure because of the printer or not. I open the fuse and printer cant start. It was stuck at restart cycle and keeps restarting. I cut the power and check for stepper drivers. They look fine. Install them again and restart the printer. Then magic smoke appeared and all drivers are dead. But printer can reach menus.
First I buy new drivers and looking for if the board is salvageable or not.
When I installed new drivers, the printer would start up, but no movement of the 3DTouch probe at startup. Its blue and red lights are constantly on.
I can manually move X, Z and E, but Y moved a little after that it became unresponsive (I tried to swap drivers, but always Y seems problematic, the drivers looks fine) .
The 3DTouch probe is not working so it can't home Z. Y cannot be homed either but I can home the X-axis. Bed and nozzle look okay; they heat up correctly. There was no error message on the printer screen. Two trees uses a custom Repetier version. This is Pronterface's error message:
