Nous pouvons monter et baisser le volume avec le bouton de volume.<\/span><\/p>\n

Dans ce cas, le bouton de r\u00e9duction du volume de l'iPhone 7 Plus re\u00e7u ne fonctionne pas, mais le bouton d'augmentation du volume fonctionne normalement.<\/span><\/p>\n

Selon le ph\u00e9nom\u00e8ne de dysfonctionnement, nous pouvons conclure que le probl\u00e8me provient probablement du circuit associ\u00e9 au bouton de volume. Tout d'abord, v\u00e9rifiez la valeur de la diode sur le connecteur du bouton de volume J4504, les valeurs sont normales. <\/span><\/p>\n
