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

Your stereo system must have a sub woffer pre-out or sub woffer output.

the amp has power, ground and emote turn on? is the amplifier lighting up? is it going into protection?check the wiring to the amp before you suspect a bad sub and amp

Hello

F 61 error means the failure of FAN
most probably dust in the fan made it to stop working so clean the dust and connect the fan to an external supply of 12v(using red and black wire) for 5 minutes and reconnect it to the unit otherwise replace the fan with new one.
Surely this will solve the problem.


Kind regards

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.

Check to see if any wires are touching or if any pins are bent in connector.

Hi,

Based on your description, the internal power supply of the subwoofer amplifier would be suspect. Often it would be a blistered or leaking filter capacitor. It is a relatively easy/inexpensive repair.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

Could be Faulty RCA wires (they bring the sound from the radio to the amp) or a bad ground (the larger black wire coming out of the amp) This is under warrranty and you should not have to worry about it... bring it back, they make fix..

May not necessarily be the out put, discontect the sub from the receiver and see if it still makes a hum, Making sure that you turn auto on, off on the sub woffer.
If it still makes a hum, then you have a earthing problem, you can get a earth filter put on your internal wiring in your home, or you can remove the earth pin on your sub woffer

If you have cables hooked up and have not installed them to the components when turned on the speaker will hum.
If your electrical outlet is not grounded properly you speaker will hum.
Personally I'd take it back and get a new one. if you just purchased it.
If this happens again try a grounded curcit first then go from there.

plug your low input into the subwoofer output of your reciever.that should get the sub working then you have to run speaker wire from your speaker outputs on your reciever into your sub in the top row of inputs then the outputs on the back of sub(the bottom row of speaker hookups go out to your speakers....my email is [email protected] if you still cant get it i can talk you through it on there or ill give you my instant messenger name is you still have problems good luck,b
