So there's a problem with my DS Lite touchscreen. When I apply pressure to the touchscreen it makes a clicking noise. It feels as if the screen isn't secure or like the adhesive(if any) is wearing off. I'm out of my warranty so would the best option be just to disassemble the DS Lite and fix it myself or just sell it/get a new one/pay for repair? I'm actually thinking of getting a new one anyway but if I fix it I could probably sell it for more to a friend.
