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

La carte SIM ne peut pas <\/span>\u00eatre reconnu au t\u00e9l\u00e9phone.<\/span><\/o_p><\/span><\/p>\n

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

Tout d'abord, nous avons besoin de t<\/span><\/span>D\u00e9montez le t\u00e9l\u00e9phone et proc\u00e9dez \u00e0 l'inspection cosm\u00e9tique de la carte m\u00e8re. Il n'y a pas de d\u00e9g\u00e2ts d'eau <\/span>ou <\/span><\/span>d\u00e9formation.<\/span><\/p>\n

Mesurer ensuite <\/span>les <\/span><\/span>tension de fonctionnement du connecteur de la carte SIM, <\/span>la valeur mesur\u00e9e sur la broche SIM_DETECT est de 0,45V, ce qui est anormal (la valeur normale de la tension doit \u00eatre d'environ 1,8V).<\/span> <\/span><\/p>\n

D'apr\u00e8s le sch\u00e9ma du circuit, <\/span>nous pouvons essayer de remplacer R202_E (100K) par un nouveau (1K).<\/span><\/o_p><\/span><\/p>\n

Apr\u00e8s l'arriv\u00e9e <\/span>remplacement de la r\u00e9sistance<\/span><\/span>alors <\/span>l'assembler et le tester \u00e0 nouveau, le probl\u00e8me est r\u00e9solu<\/span>.<\/span><\/o_p><\/span><\/p>\n

Conseils :<\/span><\/strong><\/p>\n

Pour le probl\u00e8me de la carte SIM, comme l'absence de carte SIM. Nous devons nous concentrer sur la v\u00e9rification de la valeur de la diode des broches concern\u00e9es et des valeurs de tension.<\/span><\/p>\n

S'il y a une anomalie, il faut se r\u00e9f\u00e9rer au sch\u00e9ma de principe ou aux sch\u00e9mas pour v\u00e9rifier et trouver les composants concern\u00e9s, puis le faire remplacer.<\/span><\/p>\n

Ici, dans ce cas, la tension sur le <\/span>SIM_DETECT devrait \u00eatre d'environ 1,8V. Mais le r\u00e9sultat mesur\u00e9 n'est que de 0,45V. La raison possible est donc que la r\u00e9sistance a un probl\u00e8me. Afin d'introduire une tension correcte dans le rail, nous pouvons essayer de changer une tr\u00e8s petite r\u00e9sistance.<\/span><\/p>\n
