Mastela Baby Swing Stopped Playing Music

Hi. I have a Mastela Swing and it just stopped playing music these days. I tried to open it and check the board with a multimeter beeping, looking for broken wires or broken solder points etc without success.

I then thought it could be the really small speaker board/button, so I bought a new one (same voltage and all) and tried to replace it. Again no success.

Does anyone have any ideas? The board is attached (photo, same as another forum here: Can someone help with baby swing - #7 by gaouser) as well as the swing and the speaker board I bought (green one is the original one).


The most likely problem is a broken wire between the buttons and the board. OR the battery and the board.
