It is most likely due to a bad cable connecting the screen to the main board.
The top screen must be replaced. Search YouTube for how to change it and eBay for a new screen.
Nintendo ds is older, fatter, dark screen Nintendo ds lite is thin, bright screen so you can actually see and buttons are better
The lower screen is a touch sensitive screen.
No, the Nintendo DS and Nintendo DS lite have the same screen size.
The Nintendo DS Lite has a brighter screen the the original Nintendo DS and it's slimmer as well other than that there are no huge differences
no.
One is the touch screen.
there is NT much difference...but the ds lite is acout 0.5 cm thinner and the screen is brighter there is NT much difference...but the ds lite is acout 0.5 cm thinner and the screen is brighter
The screen is 4.2 larger then the DS lite.
Yes there is, there is also a blue, red, green and white Nintendo DS.
I doubt that such a procedure could take place. The DS Lite screen is a different size to the original DS and therefore (despite all the other complications) would make this impossible.
It's probably broken
