Intenta presionar el bot\u00f3n de encendido para encender el tel\u00e9fono.<\/span><\/span>, <\/span>pero el <\/span><\/span>iPhone 7 no enciende con una gran corriente.<\/span><\/span><\/p>\n

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

Revisamos la placa base, no hab\u00eda rastro de deformaci\u00f3n ni da\u00f1os por agua. <\/span><\/p>\n

Luego conecta la placa base con la fuente de alimentaci\u00f3n de CC, la corriente salt\u00f3 a alrededor de 1,2 A, lo cual es muy grande.<\/span><\/o_p><\/span><\/p>\n

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

B<\/span><\/span>Debido a que la corriente es muy grande, algunos componentes deber\u00edan calentarse mucho.<\/span><\/p>\n

Conect\u00e9 la placa base con la fuente de alimentaci\u00f3n de CC y us\u00e9 el dedo para tocar la placa base \/ o us\u00e9 la c\u00e1mara t\u00e9rmica para localizar el \u00e1rea caliente. Se encontr\u00f3 que los componentes alrededor del conector J3801 estaban muy calientes, luego us\u00e9 el m\u00e9todo de inspecci\u00f3n de colofonia para localizar el componente caliente exacto.<\/span> <\/span><\/p>\n

La resina en un capacitor C3828 se derrite inmediatamente.<\/span><\/p>\n

Luego, mide el valor del diodo en el capacitor, el valor fue 0, lo que significa que el capacitor est\u00e1 en corto.<\/span><\/o_p><\/span><\/span><\/p>\n

Retire el condensador y vuelva a probar, el cortocircuito ha desaparecido y la corriente ha vuelto a la normalidad, el tel\u00e9fono tambi\u00e9n se puede encender.<\/span><\/o_p><\/span><\/p>\n
