Hi, First post to the forum.

I have a Creality Ender 5 Pro and have decided to upgrade the motherboard to the Bigtreetech SKR 1.4 turbo (https://www.amazon.co.uk/gp/product/...?ie=UTF8&psc=1) I've been following the teachingtech tutorial on youtube and have managed to get the firmware compiled and transferred to SD card.

Unfortunately, when I turn the printer on after connecting all the cables I get a loud constant beep from the LCD, the screen is illuminated but it's blank. I've checked the wires are in the right places and that nothing is loose or touching metal. Here is a video showing what happens https://www.youtube.com/watch?v=q44V-VJ3xjQ

When I plug the original board in everything works as it should but it just doesn't seem to like this board. If I remove the LCD ribbon, the sound stops but obviously this isn't a fix. Please can someone tell me where i'm going wrong or even point me to a forum where I might be able to get this information as i'm losing my mind.
