Dust on the screen (inside)
First determine whether the dust particles are on the outside of the screen and can be removed by cleaning the screen. To clean the screen we recommend breathing onto it and wiping it gently with a soft micro-fibre cloth.
If cleaning does not solve the problem, the Nintendo DSi will need to be returned to us for repair or replacement.
The exact cost of the repair can be found in the relevant repair price list, together with detailed information on the procedure for obtaining a repair.
