Ds Lite Top Screen Flickering and Mirrored Image.
I have made a top screen replacement in my ndsl and i make everything correctly. When i turned on the console, it worked fine, but after 15 minutes +- of gameplay the top screen starts to flicker and the image became mirrored. I have double checked everything (ribbon cable, fuse, etc...) but i dind't find anything wrong. i think the problem is the potentiometer of the upper screen, but i don't know which one is and i don't know neater the values of it.
