Chosen Solution
I dropped my DSI half the top screen is white other half plays normal. What can I do? Bottom screen works fine
The replacement screen is not really that expensive and available at places like this and here is video about the how-to. I am sure you can manage just fine and the total of the repair should be very reasonable and far LESS than a new DSi. After all, this is ifixit…;-) Of course, also make sure that the fall did not just dislodge the connector….Good Luck
