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

iPhone XR sin servicio cuando insertamos la tarjeta sim, y el IMEI era normal en ajustes, y cuando pulsamos \"*#06#\", el IMEI tambi\u00e9n era normal.<\/o_p><\/span><\/p>\n

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

Como el IMEI era normal, seg\u00fan nuestra experiencia, el problema proced\u00eda del circuito de RF(Radiofrecuencia). Desmontamos el tel\u00e9fono y comprobamos el valor del diodo en la l\u00ednea de alimentaci\u00f3n del circuito de RF. Entonces encontramos que el valor del diodo en el condensador C416_K era 0.<\/o_p><\/span><\/p>\n

Est\u00e1 en la l\u00ednea de alimentaci\u00f3n PP_3V15_LDO1_VFE_AUX desde BBPMU a los ICs amplificadores de potencia PA_UHB_K, PA_HB_K, PA_LB_K. Quitamos los condensadores en el carril, pero todav\u00eda estaba en corto, significa que el corto era de los chips.<\/o_p><\/span><\/p>\n

Entonces tenemos que quitar uno por uno. Cuando quitamos el chip PA_HB_K, el cortocircuito desapareci\u00f3, luego reemplazamos otro chip PA_HB_K y volvimos a poner otros tapones y chip.<\/o_p><\/span><\/p>\n

Y probado de nuevo, el servicio volvi\u00f3 a la normalidad.<\/o_p><\/span><\/p>\n
