Ph\u00e9nom\u00e8ne de dysfonctionnement<\/span><\/b><\/p>\n

<\/span><\/b><\/p>\n

Recevoir un iPhone 7 Plus endommag\u00e9 par l'eau qui ne s'allume pas.<\/span><\/p>\n

Apr\u00e8s une v\u00e9rification minutieuse de l'\u00e9tat cosm\u00e9tique, il y a de la corrosion autour du module Wi-Fi et l'\u00e9tiquette d'\u00e9tanch\u00e9it\u00e9 est rouge.<\/span><\/p>\n

<\/span><\/p>\n

D\u00e9pannage<\/span><\/b><\/p>\n

<\/span><\/b><\/p>\n

D'abord, nettoyez la zone moisie avec un nettoyeur de PCB autour du Wi-Fi, puis connectez l'alimentation CC, le courant a grimp\u00e9 \u00e0 une valeur tr\u00e8s \u00e9lev\u00e9e.<\/span><\/p>\n

<\/span><\/p>\n

<\/span><\/p>\n

\"Dommages<\/span><\/p>\n

<\/span><\/p>\n

V\u00e9rifiez la ligne PP_BATT_VCC et la ligne PP_VDD_MAIN, ces deux lignes sont normales apr\u00e8s avoir v\u00e9rifi\u00e9 la valeur de la diode.<\/span><\/p>\n

\"\" \"\"<\/span><\/p>\n

<\/span><\/p>\n

\n

W<\/span><\/span>Lorsque nous avons v\u00e9rifi\u00e9 la ligne PP_VDD_BOOST, la valeur de la diode \u00e9tait de 0, ce qui signifie que cette ligne \u00e9tait en court-circuit.<\/span><\/p>\n

<\/span><\/p>\n

\"\"<\/span><\/p>\n

<\/span><\/p>\n

T<\/span><\/span>Il y a tellement de composants et de puces sur cette ligne que nous devons d\u00e9couvrir lequel a \u00e9t\u00e9 court-circuit\u00e9. <\/span><\/p>\n

Ici, nous pouvons utiliser la m\u00e9thode d'inspection \u00e0 la colophane pour trouver le composant en court-circuit.<\/span><\/p>\n

D'abord, d\u00e9posez un peu de fum\u00e9e de colophane sur la surface de ces composants et puces. <\/span><\/p>\n

<\/span><\/p>\n

\"\"<\/span><\/p>\n

<\/span><\/p>\n

\"\"<\/span><\/p>\n

<\/span><\/p>\n

Ensuite, utilisez les pointes du multim\u00e8tre pour vous connecter \u00e0 l'alimentation en courant continu, une pointe \u00e9tant connect\u00e9e au c\u00f4t\u00e9 positif du composant et l'autre pointe \u00e9tant connect\u00e9e \u00e0 la masse. Et nous r\u00e9glons la tension de sortie \u00e0 3 V.<\/span><\/p>\n

\"Dommages<\/span><\/p>\n

<\/span><\/p>\n

Une fois connect\u00e9 \u00e0 la carte m\u00e8re, nous avons constat\u00e9 que la colophane sur le condensateur C3002 avait fondu. <\/span><\/p>\n

<\/span><\/p>\n

\"\"<\/span><\/p>\n

<\/span><\/p>\n

Puis remplacez <\/span>C3002 par un neuf et j'ai mesur\u00e9 \u00e0 nouveau la valeur de la diode sur PP_VDD_BOOST, le court-circuit avait disparu.<\/span><\/p>\n

\"\"<\/span><\/p>\n

Assemblez le t\u00e9l\u00e9phone et testez-le \u00e0 nouveau, probl\u00e8me r\u00e9solu.<\/span><\/span><\/p>\n
