The sound on my sons leapster 2 has stopped

Hello,
there are three basic reasons why the leapster explorer won't bring out sound.
1. Defective speaker
The speaker of your leapster explorer maybe defective, this can make it not bring out any sound. Disassemble the leapster explorer, check the speaker part, test the speaker with a AA battery. If you hear any sound using the battery, then it means there is nothing wrong with the speaker.
2. Loose wire connection
Disassemble the leapster explorer, check the wires connecting the speaker to the board. Check for any wire cut, or loose connection which can cause the speaker not to bring out sound. . 3. Sound IC/Card/Board
If non of the above is the cause of the problem, then it means the leapster explorer is having a defective sound ic/board/card. There is an IC on the board of the leapster explorer which is responsible for sound. If this ic has a shot, there won't be any sound. If this be the cause, I think it's high time to took the leapster explorer to a repairman because this requires skill.
I hope the above is clear. If not, please let me know for further assistance.
Regards.

Change the batteries to all new ones of the same brand. Most of the rechargeable ones are not powerful enough. My kids have that problem every time the batteries get low.

I am having the same issue. Devasted child as birthday gift won't work. After you choose name the screen goes blank. Please help:(

Try returning it to the store where you bought it for an exchange. Also, try checking the battery and making sure it keeps a good charge. We had problems with my son's and it was just a matter of low battery function. Good luck!
