mine is doing the same thing. it's brand new. my daughter got it for christmas yesterday. i've even tried it on my husband's macbook. both our macbooks are up to date and her leap pad works. i'm about ready to take this stupid thing back to the store. it synced all the books except for her tangled book and will not sync again. i've even tried to restore back to factory settings and it won't even do that. i've deleted and reinstalled the leapfrog connect app 3 times. also seems that the stupid pen sucks down battery juice. i've put brand new lithium batteries in the pen and after 2 hours the pen is acting like it's dying and the only thing we've been doing is trying to sync it.

If it is under warranty, you may be able to get it replaced; however, you may have to consider getting a new leapster.

Have you tried putting new batteries? If yes and still has no sound then look for the warranty and bring it back to the store where you bought it so they can repair it for free.

It might be the batteries or the brand of batteries. My son has had the tag reader for over a year now and we seldom change the batteries. Leapfrog may be against it, but we use rechargable enegerizer batteries. I can count on 1 hand how many times I've changed the batteries in the last 18 months.

You can purchase new one from amazon LeapTV Educational Active Video Gaming for Kids. I hope this was helpful. cheers

I would completely remove the software and reinstall it. I recently bought the Tag Jr after already having a regular Tag installed on my computer, and had to completely re-download everything. LeapFrog's website today also said that they were experiencing much higher than normal traffic, and some applications may not work as well or as fast.

The ac adaptor has to be set to the correct voltage , there should be a small adjuster on the mains plug.
1.5v for each battery ( regardless of battery size ); so 6v for a 4 battery , 9v for 6 battery , etc.

Hello I will try to help you. If the pen was working up until the batteries died then the problem logically would be solved by putting in new batteries. That said, remove the "new" batteries and install them in another device to be sure that they are good. Some new batteries die in the package before being used.

Then make sure you are putting the batteries in correctly, pay attention to the + and -.

Finally, you can clean the ends of the battery chamber by using a pencil eraser and rubbing it on the metal contacts.

Let me know if one of these things fixes your problem as I have additional ideas.
