SKR 1.3 not detected via usb and LCD no longer works

Hi,
I am a happy user of SKR 1.3, however for some stupid reason, I decided to plug my LCD into the board whilst it was on.

I did unplug the LCD to allow faster firmware upload, in visual code editor but I forgot to turn of the power to skr 1.3, plug the LCD in and restart the board as I would normally do.

Now the board comes on, but is not detected by my laptop or octoprint like it was before even the LCD lights are on but no display is on.

Should I just buy a new board or is there a way to fix this.

Please help

USB is directly connected to the processor on this board.

Try uploading the firmware via sd card one more time, but if there is no change its dead. Only way to fix would be to replace the LCP1768 chip.

... check the +5V - eventually damaged the 5V-regulator?

most of this board is 3.3v...

but if you do suspect 5v issues you can take 5v from usb instead of internal 5v regulator. Just move the DC select jumper to USB

I tried that but can't remember what happened with the board, I'll let you know if I get any luck...

If this works then the remaining issue will be with baby stepping...
How would I get this working with octoprint is there a script or addon for baby stepping
