I have been using this prduct since 1 year and now it stoped playing sound lights are there but no sound i changed the batteries too. its not working

Based upon your brief description, it sounds like the internal speaker itself has worn out (likely cause) or possibly the internal speaker wire(s) have become disconnected.

BTW, I am not affiliated in any way with the eBay seller nor do I work for LeapFrog... I'm a Computer Engineer/Geek in Cincinnati, Oh trying to solve a simple toy problem. All opinions expressed are solely my own and do represent any technical guidance from the original equipment manufacturer.

LeapFrog has discontinued product support of our "Learn & Groove" Musical Table with green legs that was made in 2010. LeapFrog Customer Service declined to discuss replacement parts, so I searched eBay for an exact speaker replacement.

Correct replacement speakers are available on eBay and ship from Hong Kong... I just bought qty2 of these speakers for $5.69 total inc s/h/p (only 1 was needed). Delivery time was slow, but well worth the wait...

When the replacement speakers arrived, I had to take off the back panel screws and unsolder the original speaker, so I could resolder in the single replacement speaker under the 2" black cover. The "Learn & Groove" Musical Table speaker now works great!

Some forum posts say that resoldering a computer modem speaker (16ohm .25w) could be used, but this is a temporary solution at best. The replacement speaker from Hong Kong produces a better quality sound and more sound volume when used with the "Learn & Groove" Musical Table.

The speaker replacement specs for the LeapFrog "Learn & Groove" Musical Table with Green Legs are as follows:

"Round Aluminum Shell Magnetic Type Slim Speaker Horn"
.25 watt
Resistance 16 Ohm
Type Internal Magnetic, Slim
Shape Round
Bottom Diameter 20mm/ 0.8"
Outer Diameter 35mm/ 1.4"
Height 9mm/ 0.35"
Material Aluminum, Metal, Plastic

This replacement speaker worked great for me and now my Granddaughter can again enjoy her toy that I was able to fix!

That is a very easy solution just let it go and use somthing different untill you can get another one or look in a pawn or goodwill shop.
