Occasionally, my 3DS touchscreen will have this black lines appear on it and disappear like static. The screen will also shift left to right and then go back to normal. Sometimes the entire screen will appear black and static movement and then go back to normal. It seems like something is wrong with it electronically. Otherwise it works fine and have no problem actually touching the screen. If i replace the LCD, will this fix it? Also, If a 3DS XL D-Pad only works in one direction (Only moves Down, Doesnt move Left-Right-Up), can that be fixed by replacement D-Pad or just modifying the hardware?
