"There is nothing inserted in the game card slot" is a common error that you face when you try to start a game from the HOME Menu.

What you have to do is to power off the Nintendo 3DS console and remove the game card.Then insert it again into the 3DS slot and turn on the console. Usually this happens because of quick inserting the game card or because of bad contact between 3DS and game card.

If that didn't work then try another 3DS game so that you can be sure that there isn't a problem with the 3DS console. If this problem is occurring with multiple games, the system will need to be repaired.

In case your 3DS plays the other games that you have,then the faulty 3DS game card needs to be repaired.

One common problem of all the LCD screens (3DS, televisions , mobile phones) is dead or stuck pixel.
If a pixel of your LCD screen is black and it can't change color then this is a dead pixel. If a pixel is stuck in any other color other than black then this is a stuck pixel.

Usually you'll have about 1-2 pixel stuck or dead and will remain limited to those pixels, and will not get any worse.

There is only one way to repair the stuck pixels by using a color blinking video.Unfortuanly 3DS doesn't read any video files from the SD card with the current firmware nor plays Youtube videos.

Here is a color blinking video on youtube



So right now just play for a week and if the problem remaing then return it to Nintendo as 3DS does carry a one-year warranty.

Hope that helps. Please post your comments or tips about dead or stuck pixels
