sony kdl32R 435A falta 5 volts a puerto usb

[jonny3000]

buenos dias amigos, comparto esta experiencia, por si a alguien le sirve, llego este tv, en cuestión, con la clásica leyenda en pantalla, (el dispositivo, usb, esta consumiendo demasiada energía), midiendo el puerto me encontré con la faltante de los 5v. llegando al regulador ubicado en la posicion ic3000
reemplace este componente, y se soluciono el problema, el tv. es con fuente externa
saludos amigos.-

Thanks for sharing the details.Nulls BrawlI had a similar issue before, and checking the voltage levels at key points really helped me isolate the problem.

Good point about checking the voltage levels. In many cases with these Sony models, the fault does trace back to the regulator component near the USB section. Once that’s replaced, the USB port usually works fine again without triggering the overload warning.
