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

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

Le t\u00e9l\u00e9phone s'allume normalement, mais l'\u00e9cran tactile ne r\u00e9agit pas.<\/span><\/p>\n

<\/span><\/b>Pour les <\/span>Probl\u00e8me d'absence de touche sur l'iPhone X. Tout d'abord, nous devrions t<\/span><\/span>n d\u00e9montant le t\u00e9l\u00e9phone et en proc\u00e9dant \u00e0 une inspection cosm\u00e9tique de la carte m\u00e8re, on constate des traces de d\u00e9g\u00e2ts d'eau autour du J5800.<\/span><\/p>\n

Nettoyez ensuite l'endroit endommag\u00e9 par l'eau \u00e0 l'aide d'un nettoyant pour PCB. Et r\u00e9cup\u00e9rez le <\/span>L'afficheur est install\u00e9 et le connecteur de la batterie est connect\u00e9 \u00e0 l'alimentation en courant continu pour le test, la lecture du courant sur l'amp\u00e8rem\u00e8tre est normale. <\/span><\/p>\n

Mesurez ensuite la valeur de la diode de J5800, la valeur mesur\u00e9e de la diode de la broche 28 (<\/span>PP5V25_TOUCH_VDDH<\/span>) est OL, ce qui est anormal. Selon le sch\u00e9ma du circuit, les 5,25 V sont transmis de U5600 \u00e0 la broche 28 de J5800 par l'interm\u00e9diaire de C5891.<\/span><\/p>\n

Le sch\u00e9ma de principe ci-dessous sert de r\u00e9f\u00e9rence.<\/span><\/p>\n

Nous nettoyons ensuite la colle autour de J5800 et constatons que FL5891 est compl\u00e8tement corrod\u00e9. Le tampon de collage est oxyd\u00e9 et noirci.<\/span><\/p>\n

Nous avons donc gratt\u00e9 le pad avec un couteau et mis quelques tins avec un fer \u00e0 souder, puis nous avons court-circuit\u00e9 le pad. Apr\u00e8s cela, nous avons mesur\u00e9 la broche 28 de J5800 \u00e0 620, ce qui est normal. Nous avons mont\u00e9 la carte m\u00e8re et test\u00e9 \u00e0 nouveau, l'\u00e9cran tactile est redevenu normal, le probl\u00e8me est r\u00e9solu.<\/span><\/p>\n
