iPhone XR keinen Dienst, wenn wir die Sim-Karte einlegen, und die IMEI war normal in den Einstellungen, und wenn wir dr\u00fccken \"*#06#\", die IMEI war auch normal.<\/o_p><\/span><\/p>\n

Da die IMEI normal war, lag das Problem unserer Erfahrung nach am HF-Schaltkreis (Radiofrequenz). Wir zerlegten das Telefon und \u00fcberpr\u00fcften den Diodenwert an der Stromleitung f\u00fcr den HF-Schaltkreis. Dann stellten wir fest, dass der Diodenwert am Kondensator C416_K 0 war.<\/o_p><\/span><\/p>\n

Es liegt an der Stromleitung PP_3V15_LDO1_VFE_AUX von BBPMU zu den Leistungsverst\u00e4rker-ICs PA_UHB_K, PA_HB_K, PA_LB_K. Wir haben die Kondensatoren auf der Schiene entfernt, aber sie war immer noch kurzgeschlossen, das hei\u00dft, der Kurzschluss kam von den Chips.<\/o_p><\/span><\/p>\n

Dann m\u00fcssen wir einen nach dem anderen entfernen. Als wir den Chip PA_HB_K entfernt haben, war der Kurzschluss verschwunden, dann haben wir einen anderen Chip PA_HB_K ersetzt und die anderen Kappen und den Chip wieder eingesetzt.<\/o_p><\/span><\/p>\n

Und wieder getestet, war der Dienst wieder normal.<\/o_p><\/span><\/p>\n
