Hi this is my first post here. I recently purchased an mpcnc kit and today I got around to plugging in the LCD to the ramps board but the LCD lights up and does nothing else if I swap the cables the LCD just clicks. The clicking sound happens and there is a flashing of the screen that is very faint. Not sure what’s going on here any help would be greatly appreciated thank you.
Here is a quick video of it as well https://drive.google.com/file/d/1lSi5EkOCQlSywuSWuGEnZd61ms7Liu_5/view?usp=drivesdk
If it has shields they are backwards (for our screens), link and fix shown above.
Wow okay I see that now. Like literally turn the pinhead over thanks for the info. Sorry for the rookie mistake.
All good now. Thanks.
