Hi I got my son a new 3DS 2 days ago for his birthday, along with the new lego star wars game. It was great at first until the images started to go blurey. We tried powering it on & off a couple of times, taking the game out etc etc. Nothing made a difference. The screen is fine when the slider is not in 3D, but slide it up & its pointless. Luckily as its from Amazon & only a couple of days old, they are sending a replacement for him. This is just a warning really. I will be checking posts on here to see if this issue becomes a common one. Cheers.

make sure you are looking at it in the right angle

yeah im having some blurs on my screen in 3d. its like a double image, but i am lking at it the right way

I haven't had any problems with mine, but I don't use the 3D very often and when I do it's on the lowest setting.

Erm this is definetly the wrong forum for this...

How old is your son?

You have to look straight at the screen to see the 3d properly otherwise you do get blurred vision or even doubled.
