Tengo un TL-WPA4220 que hace ruido cuando esta enchufado y ha dejado de funcionar

 

hola,

 

tengo un TL-WPA4220 y ya hacía meses que se oía un ruido muy agudo pero el aparato funcionaba bien.

El otro día, de repente dejó de funcionar y solo se encendían y apagaban las luces. Parecía que tenía conexión, a los 10 segundos se apagaban las luces, y se volvían a encender. Y así, repetidamente. como si se resetease continuamente cada 10 segundos.

Intenté emparejarlo repetidamente y no había forma.

 

Lo he abierto y no veo nada quemado. En otro hilo he visto que alguien cambió un condensador verde que estaba algo hinchado, y volvió a funcionar correctamente. Yo no he visto ningún condensador hinchado, pero podría estar cortocircuitado sin que viese por fuera.

¿Alguien sabe qué le sucede y si tiene solución?

 

Como creo que no está en garantía, no me importa trastear con él. ¿Alguien tiene un esquema electrónico del aparato? Sería de gran ayuda.

gracias

 

 

I have a TL-WPA4220 that makes noise when plugged in and has stopped working

 

hello,

 

I have a TL-WPA4220 and I had been hearing a very high-pitched noise for months but the device worked fine.

The other day it suddenly stopped working and just the lights went on and off. It seemed like it had a connection, after 10 seconds the lights went off and came back on. And so on, repeatedly. as if it resets continuously every 10 seconds. I tried to pair it repeatedly and there was no way.

I have opened it and I don't see anything burned. In another thread I saw that someone changed a green capacitor that was somewhat swollen, and it worked correctly again.

 

I have not seen any swollen capacitor, but it could be shorted without me seeing from the outside.

Does anyone know what is happening and if there is a solution?

Since I don't think it's under warranty, I don't mind messing around with it. Does anyone have an electronic diagram of the device? It would be a great help. thank you
