Fen\u00f3meno del mal funcionamiento<\/span><\/b><\/p>\n

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

Pulsa el bot\u00f3n de encendido para encender, el iPhone X no se puede encender.<\/span><\/p>\n

Soluci\u00f3n de problemas<\/span><\/b><\/p>\n

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

Desmonte el tel\u00e9fono y retire el conjunto de la pantalla, a continuaci\u00f3n, conectado al cable de alimentaci\u00f3n de CC, la lectura de corriente en el amper\u00edmetro es 50MA, que es anormal. <\/span><\/p>\n

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

A continuaci\u00f3n, separe la capa superior y la capa inferior de la placa base, luego conecte las dos capas de las placas base con el accesorio de prueba i<\/span>S<\/span><\/span>ocket y conectado con la m\u00e1quina de alimentaci\u00f3n de CC para comprobar la corriente de nuevo, la lectura sigue siendo 50MA. Esto significa que la fuga de corriente no es causada por la conexi\u00f3n entre las dos capas de las placas base.<\/span><\/span><\/span><\/p>\n

\"El<\/span><\/p>\n

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

Continuamos midiendo el voltaje y el valor del diodo en la capa superior, encontramos que el voltaje en C2771 y C2770 era 0, pero el valor del diodo era normal. <\/span><\/span><\/p>\n

\"\"  \"\"<\/span><\/p>\n

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

Seg\u00fan el diagrama de bloques del circuito, el voltaje se emit\u00eda desde el pin W16, pin W17, pin W18 en U2700(PMU), y luego se introduc\u00eda en la CPU a trav\u00e9s de L2770.  <\/span><\/span><\/p>\n

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

Trate de reemplazar otro inductor L2770, encendi\u00f3 la placa base, y comprob\u00f3 la tensi\u00f3n de nuevo, la tensi\u00f3n de nuevo a la normalidad.<\/span><\/span><\/p>\n

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

Despu\u00e9s de reemplazar el inductor, volver a soldar la capa superior y la capa inferior juntas, ensamblar todas las piezas y probar de nuevo, el tel\u00e9fono se puede encender normalmente, problema resuelto.<\/span><\/p>\n
