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

Despu\u00e9s de sustituir otra pantalla, el fallo segu\u00eda siendo el mismo. Entonces abrimos los esquemas para comprobar el circuito de retroiluminaci\u00f3n. Pudimos ver que el circuito de retroiluminaci\u00f3n era similar al de los modelos de la serie P de iPhone, como el 6 Plus o el 7 Plus. Hab\u00eda dos conjuntos de chips de luz de fondo, U5650 y U5660, si uno de los circuitos estaba roto, la mitad de la luz de fondo LED no funcionar\u00e1.<\/o_p><\/span><\/p>\n

Entonces la pantalla podr\u00eda estar medio apagada y medio encendida.<\/o_p><\/span><\/p>\n

Montamos la pantalla y encendimos el tel\u00e9fono, y comprobamos la tensi\u00f3n en C5652 y C5662, el valor normal debe ser superior a 10V, si el valor era s\u00f3lo alrededor de 4V, significa que el circuito correspondiente estaba da\u00f1ado.<\/o_p><\/span><\/p>\n

Despu\u00e9s de comprobar, encontramos que el voltaje en C5652 era anormal, entonces tratamos de reemplazar la luz de fondo IC U5660 y probado de nuevo, la funci\u00f3n de luz de fondo volvi\u00f3 a la normalidad.<\/o_p><\/span><\/p>\n
