Cours th\u00e9orique sur l'iPhone 11 pro<\/a>Pour cela, il faut d'abord tester les composants li\u00e9s \u00e0 PP_VDD_MAIN, comme le circuit int\u00e9gr\u00e9 de charge et les petits composants qui l'entourent.<\/p>\n![\"R\u00e9paration](\"https:\/\/rewa.tech\/wp-content\/uploads\/2024\/04\/ChargingiC_U4000.png\" "\\"\\"")

S\u00e9parez les deux couches de la carte m\u00e8re, puis retirez le couvercle de blindage sur le circuit int\u00e9gr\u00e9 de charge et appliquez de la colophane. Apr\u00e8s cela, connectez l'appareil \u00e0 une source d'alimentation en courant continu pour fournir une tension de 4 volts. Aucun court-circuit n'a \u00e9t\u00e9 d\u00e9tect\u00e9.<\/p>\n
Appliquer ensuite de la colophane sur la surface de la deuxi\u00e8me couche de la carte m\u00e8re (carte de signal), puis assembler les deux couches de la carte m\u00e8re \u00e0 l'aide d'un dispositif de test.<\/p>\n

Appliquer \u00e0 nouveau le courant continu de 4 volts, et la magie op\u00e8re ! La colophane \u00e0 la surface du C1900_E a fondu.<\/p>\n
Le court-circuit doit donc provenir du petit condensateur.<\/p>\n

Comme il s'agit d'un condensateur de type filtre sur le rail PP_VDD_MAIN, nous pouvons le retirer directement.<\/p>\n<\/p>\n

Apr\u00e8s cela, assemblez le t\u00e9l\u00e9phone et testez \u00e0 nouveau, le t\u00e9l\u00e9phone peut \u00eatre d\u00e9marr\u00e9 normalement, le probl\u00e8me est parfaitement r\u00e9solu par le remplacement du condensateur.<\/p>\n<\/p><\/p>","protected":false},"excerpt":{"rendered":"
