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

Seg\u00fan el fen\u00f3meno de aver\u00eda, se trataba de un problema de retroiluminaci\u00f3n.<\/span><\/p>\n

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

En primer lugar, podemos cambiar otra pantalla para probar, el fen\u00f3meno fue el mismo, entonces podemos comprobar los circuitos de luz de fondo mediante la medici\u00f3n de los valores de diodo en los pines pertinentes del conector de pantalla J4502, todos los valores de diodo en los pines pertinentes eran normales.<\/span><\/p>\n

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

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

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

Continuamos comprobando los valores de los diodos en los peque\u00f1os componentes alrededor del IC de retroiluminaci\u00f3n, hay dos IC de retroiluminaci\u00f3n en el iPhone 7 plus, U3701, y U4601.<\/span><\/p>\n

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

Especialmente los valores de los dos diodos D3702 y D4602, el valor normal deber\u00eda ser alrededor de 200. Despu\u00e9s de la medici\u00f3n, los valores de los diodos eran normales.<\/span><\/p>\n

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

Entonces comprobamos la conexi\u00f3n de M2800 midiendo en el lado A de D3702 y Pad 1 de C3718, mostr\u00f3 OL, lo que significa que M2800 estaba roto. <\/span><\/p>\n
