A<\/span><\/span>Gem\u00e4\u00df dem St\u00f6rungsph\u00e4nomen k\u00f6nnen wir zun\u00e4chst versuchen, den SIM-Kartenleser zu \u00fcberpr\u00fcfen. <\/span><\/p>\n

Messen Sie die Diodenwerte am SIM-Kartenleser J_SIM_RF mit dem Multimeter. Wir haben festgestellt, dass der Wert an Pin 0 betrug, was bedeutet, dass Pin 1 einen Kurzschluss gegen Masse hatte.<\/span><\/p>\n

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

\"\" \"\"<\/span><\/p>\n

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

Aus den Schaltpl\u00e4nen ging hervor, dass Pin 1 von J_SIM_RF \u00fcber C5610_RF, C6900_RF, DZ6901_RF mit dem BBPMU und der Basisband-CPU BB_RF verbunden war. Lassen Sie uns also fortfahren, die kleinen Komponenten und Chips zu \u00fcberpr\u00fcfen. <\/span><\/p>\n

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

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

Entfernen Sie die 3 Komponenten nacheinander, aber der Kurzschluss bestand weiterhin. Versuchen Sie dann, die BBPMU zu entfernen und den Diodenwert erneut zu messen, der Kurzschluss war weg. <\/span><\/p>\n

Das Problem sollte also von BB_PMU herr\u00fchren, lassen Sie es austauschen und testen Sie es erneut, die Funktion ist wieder normal, das Problem wurde behoben.<\/span><\/p>\n
