Top of NDS keep flickle

does anyone knows why the top screen of NDS will flickle and how much to repair? or is it cheaper to buy a new one?

Hi AlvinSee, I have had that problem in the past. What I did when I saw that happen was that I moved the top part slowly side to side and the flickle was gone. I also have called Nintendo at first but my warranty expired so what I had to do was pay about 60 bucks. It's not worth it. also, if you go google, "Fix screen" on NDS, it might help. Hope this helped...

Might have to bring it in to a specialist.
