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

iPhone XR no se puede encender con una gran corriente cuando se conecta con la m\u00e1quina de alimentaci\u00f3n de CC<\/p>\n

Desmontamos el tel\u00e9fono y comprobamos si hab\u00eda alguna zona da\u00f1ada por el agua u otra aver\u00eda evidente, cuando se conecta con corriente continua, la corriente es muy grande, en nuestra experiencia, la aver\u00eda normalmente de la siguiente zona en color rojo.<\/span><\/p>\n

Comprobamos los valores de los diodos de las tres l\u00edneas, pero todos est\u00e1n bien. Entonces bajamos el voltaje de salida de la maquina de corriente continua y conectamos con la placa base para comprobar que parte estaba caliente. Entonces podemos sentir que el \u00e1rea alrededor de U5002 estaba caliente. <\/o_p><\/span><\/p>\n

Quitamos la cubierta de blindaje y comprobamos el valor del diodo en los condensadores alrededor del chip, encontramos que los condensadores de la zona roja estaban en cortocircuito. Entonces intentamos quitar uno por uno, cuando quitamos C5021, el cortocircuito desapareci\u00f3. Despu\u00e9s volvimos a poner otras tapas y sustituimos otro condensador, el problema se resolvi\u00f3.<\/o_p><\/span><\/p>\n
