Merci à ce tutoriel, j'avais exactement le même problème, mais après avoir soudé ce truc 5 fois et que ça recassais, j'ai poncé un peu la board, refais la soudure et fixé cette maudite pièce au pistolet à colle, tout autour de la prise jack. Plus de soucis. Le design est vraiment mal fait car cette pièce n'est pas bien tenue en place et les enfants font pas toujours gaffe en branchant. Bref. Merci 1000 fois pour ce tuto, je n'aurais jamais trouvé sinon.

Bonjour.

Merci pour ce tuto. Malheureusement, mon cas est plus grave. C'est une des lamelles du connecteurs qui est cassée. Avez vous la référence du connecteur pour le changer ? Merci
