I had this problem, too, and ended up throwing away the subwoofer. The reason in my case was the amplifier had a blown resistor. I could clearly see the burn marks and the broken resistor. I could have fixed it, but the subwoofer is 9 years old.
To find this, I unscrewed all of the bigger screws on the back except the two with the "ring" around the screw head. I then unscrewed all of the small screws. The amplifier/controller will come apart. Disconnect the speaker from the amp and then open the amplifier itself. In the "box" you will see a metal bracket, which was where the burnt resistor is.
Hope this helps.

My sub is making a rattling sound. I dont know what it is, and I dont play my movies that loud. I also have the sub power only about 40%, I dont know whats wrong with it


First pick it up and shake it, to see if something is loose inside it!
Sometimes the speaker cone can become damaged. If you can get at it, gently press it so it moves up & down. Don't press it from the side, just apply force all over. It should just move without scraping. If it doesn't the cone is damaged.

I have a sub woffer JHT525 that bega humming. I have checked the fuze and did some reconnections but it is still humming. Anu suggestions? Anyone know where I can get a replacement. The model is JHT525


Disconnect everything, and turn it on. If it hums, it needs repair. Then try hooking up one cable at a time. If a connection hums, try another cable. If it hums no matter where you plug it in, try a 2-prong power plug adapter, or a ground-lift plug, as it's called. If nothing works, it may need a repair in its power supply. It would still turn on, but buzz no matter what you connect.

Loud hHum from Subwoofer


Sounds like the hum might be mains hum caused by the failure of the power supply capacitor(s) in the sub. It/they will be the largest on the pc board. You will find all the details (needed to replace it) on them. If you find more than one replace both.

See if any electrolytic filter capacitors are blown (bulged at the top), badly soldered or if they have broken contact pins (legs), a loud hum in the audio suggests there is a non rectified (AC) voltage present which could be caused by a bad or badly connected filter capacitor.

There may as well be other reasons for the hum (a bad earth connection,a loosely plugged or badly soldered audio or internal connector, bad rectifier bridge or diodes, as the case may be, bad solder joints on any component, possibly other components that are faulty).

I just suggested some of more common possibilities.

Hope you can fix it.

Sounds like your connection is bad on the wiring to the Subwoofer. Try rewiring the connection with new wire.

No tengo volumen , no puedo escuchar musica....


Yo comprendo un pequito de Espanol, pero nada de Windows en Espanol.

Control Panel, Sounds and Audio Devices, Volume.

Sea seguro; "mute" no se comprueba, y el volumen es máximo

Buena suerte, amigo.
