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

L'iPhone XR n'affiche aucun signal lorsque l'on ins\u00e8re la carte SIM ; l'IMEI s'affichait correctement dans les r\u00e9glages, et lorsque l'on compose \u201c *#06# \u201d, l'IMEI s'affichait \u00e9galement correctement.<\/o_p><\/span><\/p>\n

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

Puisque l'IMEI \u00e9tait normal, selon notre exp\u00e9rience, le probl\u00e8me provenait du circuit RF (Radiofr\u00e9quence). Nous avons d\u00e9mont\u00e9 le t\u00e9l\u00e9phone et v\u00e9rifi\u00e9 la valeur de la diode sur la ligne d'alimentation du circuit RF. Ensuite, nous avons constat\u00e9 que la valeur de la diode sur le condensateur C416_K \u00e9tait de 0.<\/o_p><\/span><\/p>\n

C'est sur la ligne d'alimentation PP_3V15_LDO1_VFE_AUX du BBPMU vers les circuits int\u00e9gr\u00e9s d'amplificateur de puissance PA_UHB_K, PA_HB_K, PA_LB_K. Nous avons retir\u00e9 les condensateurs sur le rail, mais il y avait toujours un court-circuit, ce qui signifie que le court-circuit provenait des puces.<\/o_p><\/span><\/p>\n

Ensuite, nous devons les retirer un par un. Lorsque nous avons retir\u00e9 la puce PA_HB_K, le court-circuit a disparu, puis nous avons remplac\u00e9 cette puce PA_HB_K par une autre et remis en place les autres condensateurs et puces.<\/o_p><\/span><\/p>\n

Et test\u00e9 \u00e0 nouveau, le service \u00e9tait revenu \u00e0 la normale.<\/o_p><\/span><\/p>\n
