Professor Smartie that “screw thing’ is actually a '''V'''ariable '''R'''esistor. Some people also call the (Trim) Pot for Trimmer Potentiometer. Your DS Lite should have two of those. VR1 is for the upper display and VR2 for the lower display with touch. Measured looks like a 50K pot. Set your pot that the resistance is around 15K between point 1 and 2 and 23.5K between point 2 and 3. To high and your screen may just fail or your power circuit, so be careful . BTW, you do realize that this needs to be soldered in place. Now for as to where to get it, I’d start at places [link|https://www.digikey.com/en/products/detail/panasonic-electronic-components/EVM-2NSX80B54/674260|like this]
