Blank screen when BLTouch connected to servo and probe pins on 1.4 Turbo board #419

I just installed a new 1.4Turbo board and all seems well except that when I connect all 5 pins of the BLTouch (3 servo pins and 2 probe pins), the LCD goes blank and the printer won't respond. I have a creality BLTouch with red, blue and yellow wires for the servo and black and white wires for the probe.

Can someone please give me some guidance here?

thanks.

I'm having the same issue with a BTT SKR E3 Turbo board. Hoping we both get help on the issue?

i think it'll be the endstop wires. iwas using 3 wire endstops and this happened. i swapped em round (a few times) and it solved the problem. might be worth a try

Yeah, it turned out to be the servo wires actually. I ended up having to switch the blue and red wire in the connector and then it worked fine. This issue can be closed now I suppose.
