<\/span><\/b>Pour les <\/span>Probl\u00e8me d'absence de signal sur l'iPhone X. De la m\u00eame mani\u00e8re, la premi\u00e8re \u00e9tape que nous allons t<\/span><\/span>D\u00e9montez le t\u00e9l\u00e9phone et proc\u00e9dez \u00e0 l'inspection cosm\u00e9tique de la carte m\u00e8re. <\/span><\/p>\n

Apr\u00e8s v\u00e9rification, le cosm\u00e9tique est OK, puis d\u00e9tachez les deux couches de la carte m\u00e8re l'une de l'autre et retirez le connecteur de la carte SIM et mesurez l'alimentation du circuit RF. Nous avons constat\u00e9 que la valeur de la diode de  <\/span>VDD_RFFE_VIO_1V8_K<\/span> est plus petit que la normale. Nous pouvons donc confirmer que le d\u00e9faut est li\u00e9 \u00e0 <\/span>VDD_RFFE_VIO_1V8_K<\/span>.<\/span><\/p>\n

Il y a trop de composants pertinents sur <\/span>VDD_RFFE_VIO_1V8_K<\/span>. Nous pouvons v\u00e9rifier et localiser le composant anormal en le touchant avec le doigt, par cam\u00e9ra thermique ou par la m\u00e9thode d'inspection \u00e0 la colophane. <\/span><\/p>\n

Enfin, nous constatons que le MHB PA est chaud lorsque l'on touche le circuit concern\u00e9 avec le doigt. Nous pouvons donc conclure que le d\u00e9faut est li\u00e9 au CI MHBPA_K.<\/span><\/p>\n

\"Probl\u00e8me<\/p>\n

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

Nous rempla\u00e7ons donc la puce par une nouvelle et remettons ensuite le connecteur de la carte SIM en place.<\/span> remettre en place le cadre central et<\/span> faire en sorte que la couche sup\u00e9rieure et la couche inf\u00e9rieure soient soud\u00e9es ensemble. <\/span><\/p>\n

Ensuite, il faut l'assembler et le tester \u00e0 nouveau, le probl\u00e8me \u00e9tant r\u00e9solu.<\/span><\/p>\n
