The audio amplifier in the unit has failed, and that's what you smell. Turn it off and quit using it immediately - it presents a fire hazard. It might be possible to replace the bad parts. Depending on what it cost, you might want to take it somewhere for a repair estimate, but be prepared to learn it might not be fixable. Often the burned parts damage the circuit board as well.

Usually this happens in small stereo systems because of running them at high volumes for a long time. If you want to listen to loud music, you would be better off putting the money into a higher-power system.

Monitiors are not turning on


Have you tried to use these on other devices, like a DVD Player, etc.? If you get a HUMMING noise with other devices then the internal amplifier is defective and you are not getting sound production to the speakers. If you have separate power AMP and the speakers hum when connected, they may have been damaged. If you have a speaker mismatch; they tend to buzz, thus too many conditions could represent the humming. Check that the Positive and Negative polarization of the speaker wires are correct.

If there is a router or you leave your phone near the speakers that is what is most likely causing the problem. Check to see if anything that gives off a wireless signal (eg. microwaves, cell phones, cordless phones) are nearby, and try to see if moving one of those things fixes your problem.

My home theater speakers make a constant hum whenever my receiver is on. The loudness of the hum changes with the volume control, and goes away entirely when the system is muted. All components are plugged...


jd40,
Sounds like a grounding issue. The first two places to look into is the powered subwoofer and antenna. During your last test, did you leave the FM antenna and subwoofer connected? Many times the hum is directly related to the antenna and/or the subwoofer and to how they are grounded; creating a ground loop through the receivers ground on the outlet. If the antenna is grounded to the dwellings wiring, hum is inevitable and sometime you can get a ground loop hum from how or how & where the subwoofer is grounded. Try taking them completely out of the loop.

Also try taking it further back to the basics, start with the receiver plugged into a known good grounded outlet with no surge or line conditioner in the loop and nothing connected to the receiver, nothing. Use one speaker and different wire to test each speaker output while in tuner and any other mode but phono. With no signal, you will either get nothing (no hum or static) or just static in the tuner mode. No hum is a good sign. Some systems will mute the speakers if no signal is connected to eliminate the static from being produced through the speakers but a ground loop hum will most likely still be produced even in mute. If you get a hum when nothing is connected to the receiver, try looking into getting a better grounded outlet, even maybe to a different dwelling.

Came home after a storm and smelled electric burning and heard a hum from the subwoofer. now i wonder what the problem is and is it worth getting fixed.


I had almost the same problem. I was Playing music and my speakers kept on shorting out, i smelled burning wires and i look in back of my subwoofers and there melted. i just simply replaced the wires exept with a thicker 14 Gauge wire. But i dont know if your subwoofer is damaged or not. but i would try changing the wires.

No its not EMI.- I have them too and mine are little over a year old. Have noticed the faint smell of electricial burning. Checked the sub and the amp/pwr supply in there must be slowly breaking down. I cant turn my speakers up past 25 percent volume and the crackling/hum gets very bad, We should all be looking for replacement at this point.

My subwoofer smells smoky and there's a humming sound..


Well,
It best to call the manufacturer to get the speaker system replaced. As you see it smell bad , could be a burnt fuse at the back of the sub.

No sound from my brand new speakers


I am assuming you have tried new speakers on used unit on both A & B choices. Have you tried your new speakers with old 2802? If they work OK with old unit, you have problem with amplifier in used unit. Take the used 2802 to a reputable shop and have it thoroughly tested. Perhaps it is just a loose connection.
