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.

Parece que el puerto USB no está recibiendo los 5V que necesita. Podría ser un problema en la placa de alimentación o en el propio regulador del televisor. Revisar los componentes cercanos al puerto USB suele ser el primer paso para identificar la falla .

Es común que el puerto USB no entregue 5V si hay un problema en la placa o un fusible dañado; revisa el regulador y las conexiones del circuito USB. .

It’s quite normal for a USB port to stop supplying 5V when there’s a hardware fault on the board or a damaged fuse in the power line. In these cases, it’s a good idea to inspect the voltage regulator, trace the USB power path, and check for any loose or burnt connections around the circuit. Careful testing with a multimeter can help pinpoint where the voltage drop or interruption is occurring.

It’s common for a device to stop delivering proper voltage if there’s a short circuit, blown protection component, or damaged power trace on the board. In such situations, you should examine the power input section, test continuity along the main line, and look for visible signs of heat damage or loose solder joints. Using a multimeter to carefully measure voltage at different points can help identify exactly where the issue begins .
