Instructions
Examine the screen discoloration. If the red discoloration appears as different dots on the screen, you can call the Nintendo Customer Service line at (800) 255-3700 for assistance. The Nintendo DS comes with a one-year warranty, and Nintendo can replace your screen for free if the discoloration interferes with game play while under warranty. Otherwise, this type of discoloration will not worsen, but may annoy or distract the player.
Contact Nintendo for an LCD screen repair if the discoloration completely covers the system's screen, even if the system is not turned on. Players can use Nintendo's online repair order system or call the customer service line to get the system's screen repaired.
Ensure that all accessories used with your Nintendo DS are licensed Nintendo products. All accessories licensed by Nintendo bear the Nintendo official seal. If you are using an accessory such as a screen protector with your Nintendo DS, it might cause discoloration if not licensed by Nintendo. Remove the screen protector and play a game to see if the red discoloration continues.
Clean your screen to remove residue that might cause red discoloration. Use soft cloths to clean the screens. Use a wet section of a cloth to gently scrub at the screens. Use a dry cloth to remove moisture. If discoloration persists, contact Nintendo's customer service department.
