My son's leapster, specifically the touch screen, doesn't work properly. What can we do?

Push the "A" button to enter the calibration.
There will be a little plus sign. Touch it with the stylus and continue to touch the plus signs with the stylus until you return to the calibration screen.
Turn the Leapster off and then back on again without a cartridge.

How did you try recaibrating? I just fixed my son's Leapster 2 a few minutes ago. I read a couple different recalibration instructions and the one that works for the Leapster 2 is:
1-Hold down the (?) Hint button while turning on the system.
2-Keep holding it down until the Leapster menu shows up
3-Let it go and press the A button
4-Touch each crosshairs x with the pen tip
5-When it goes back to the menu screen, restart the unit

The same thing is happening wit my sons and I just bought it what kan I do???

We have the same problem and our leapster is only 2 days old.Do Touch Screen Calibration,it should help.I do it everytime for my son when he wants to play and it does help...But once u turn leapster off,u'll have to calibrate it again next time...
Just hold down hint button while turning on.When the Leapster menu screen appears,press the A button.Touch each of the crosshairs that appear with the stylus.restart unit. ..That what we do everytime.

Press the ? button and hold it while turning unit on.
Press the "a" button to select touch calibration
Press each + with the stylus
Restart machine

Press the ? button and hold it while turning unit on.

Press each + with the stylus

Buy another one from the same store and just swap them.

I've tried the Home and A button several places... and it seems to work for others but not me :( I was about to give up then I found another way to reset the screen - Hope it works for you!

1. Unit must be OFF and NO cartridge
2. Hold down the HINT (?) button while turning the unit on
3. When Leapster menu screen appears, press the A button
4. Touch each of the cross hairs that appear with the stylus
5. Restart unit

Got my son's to work. Used these instructions.

Question Why doesn;t my Leapster2 respond to the stylus pen? Answer If your Leapster2 does not respond to the stylus pen, it needs to be calibrated. Calibrating the Leapster2 is easy:
1) Ensure that a cartridge is not inserted 2) Hold down the Hint button while turning the unit on 3) When the LEAPSTER menu screen appears, press the A button 4) Touch each of the crosshairs that appear with the stylus 5) Restart unit

An easy fix....

Press the ? button and hold it while turning unit on.
Press the "a" button to select touch calibration
Press each + with the stylus
Restart machine

Le voila!
