Question about Onkyo SKW-210 Subwoofer

Electrical short in the subwoofer

I have looked inside the subwoofer on my system because the piece of equipment was not working. I found that the fuse was blown. I purchased the required fuse, installed it and attempted to plug on the subwoofer, when the fuse blew again. This leaving me to believe that there is a short in the circuit somewhere. However there are no exposed wires, burnt or melted wiring and the back of the circuit board doesn't show any signs of carbon tracks. I was curious if I could get more insight. Thank you

You're quite right when a fuse blows there's a short. The short will be in either the power supply section, or the main amp. You will be looking for a semi-conductor of some sort. A multi meter on the ohm setting will track it down quick if it's a transistor. As the meter scale will be just like you have touched the probes together. Follow the circuit back from the fuse. Check any part that you suspect. If the sub uses an IC power amp, it could be a strong suspect!

Hi friends i am using kenwood subwoofer sw-300 its not working from two days, i observer relay triping sound from inside the amp relay omron g5r 2232p-kw 48vdc has continue tripping while power on,


Short circuit protection energizes. Check for any external short circuit with connecting sires to sub woofer. If it found OK, the sub-woofer output amplifier section circuit inside the set is fault. Short circuited component/s. Check and replace them. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

How to wire your subwoofers correctly...


Much like many aspects of electrical car audio must be wired properly to ensure that you don't have short circuits, fires, and damaged equipment. As an 8 year experienced car audio installer I still forget sometimes. The best thing to do if you aren't for sure is consult a resource, the two top sites that I have found that have adequate wiring diagrams and basically give you a picture of what you're supposed to be striving for. www.the12volt.com is the most highly recommended site in my book. They have a section in subwoofer wiring that allows you to choose the amount of drivers you have, the number of voice coils per driver, and the impedence of those voice coils. This is a big resource if you don't know what specific subwoofers to buy or what amp will push your currents subs to their potential. It gives you all the options for wiring possible and explains the ohm load you will be presenting to your amp ensuring fail safe wiring.

Sport craft dart what is the power suply


The power supply takes in voltage (usually 120V AC) and distributes it among the utilization equipment (motherboard, speakers, monitor). in older standup dart boards it is consists of a system of devices called a linear power supply this usually consists of a transformer, capacitors, fuses, other electrical/current altering devices that are exposed inside the cabinet of the dart board ( meaning you can be seen by simply looking inside.) These "devices" will convert the 120V into a form necessary for that which it is supplying power to. In more modern circumstances where you would see all of this equipment you will instead see a switching power supply. which consists of a metal housing with holes all over it and a on/off toggle switch on the side. Both systems have the same function however a switching power supply contains everything inside the metal housing, meaning you cannot see all of the individual pieces without taking it apart. Under both circumstances the AC power cable will plug directly into said power supply from your wall outlet making it almost impossible to miss.

Bose lifestyle 12 no power


check inside for a blown fuse.also there may be a problem with the board it's self.check to see if youre getting power through the cord and then go from there.check something electrical in the same place you plug in your bose such as a hair dryer and see if that works.if it doesn't check your fuse box for a blown fuse.

The subwoofer for that system also powers the rest of the speakers as well as the
subwoofer as you probably know. Is there any power light coming on? Like on the subwoofer itself where ever the power light is. If not check for a fuse. If no fuse is visable you'll have to take the subwoofer apart, the plate amplifire. There will be screws all around the metal part on the back, you must remove all the screws holding it together. Most of these types of systems have the fuse inside on the board. Also sometimes the fuse does'nt look like a fuse, it could look like a resistor or a ceramic style disk capacitor. Yours will probably have a glass type fuse. If you don't see one look on the board next to the components on the power supply board or if all together look near the transformer area for a F meaning a fuse. /there will be letters and numbers next to each component eg., resistor, capacitor, diode, etc. If you find a glass type fuse replace it with the exact same rating which will be on the end of the fuse on the silver ends of the fuse. If it's not blown you'll need to test to see if your getting voltge out of the transformer. You'll have to have the DVD unit hooked up to it, you don't have to have any speakers connected. The cable from the DVD unit to the subwoofer is what tells the amplifire on the subwoofer to turn on. You could have a blown amplifire IC. I don't know what type of ouput amplifires this uses but I'm thinking IC and not seperate transistors for the output amplifires. You might have one of those blown and if you do then the whole system wont work. Hopefully if that is the problem you'll see a burnt mark on the IIC itsel or some type of burnt spot on the board somewhere to lead you in the right direction to the problem. It could be as simple as a power supply capacitor, who knows til you get into it and start looking around and testing some things. If you don't have the knowledge to do this I am the cheapest electronics business in the USA. It's not a bad system, CrutchField sales it. Also I can waalk you through the steps to narrow the problem down. I help people everyday. You can contact me at ampman37@gmail.com. I can then give you some more info and my business phone number if you feel up to doing this. It's really no big deal and I find that most of my customers who have never done something like this love and learn some electronics and now fix some other stuff they had laying around. I'm here to help. Thank you for contacting me, have a good day.

I just purchased a 12"


Did you purchase your subwoofer from a retail location or online? If it was local, I would take it back. It sounds like a blown subwoofer. Pull the subwoofer out and smell it. If there is a burned smell, the coil was blown. This would also explain why the cone was not moving, just vibrating. Now the other possibility is the amplifier. Check the fuses and check where you grounded the amp. If you can use a multimeter, use it to check your ground. If it does happen to be a blown subwoofer, you should be able to exchange it (from retail), online takes more time but can be done. However, if you purchased from an individual and the equipment is used, there isn't a whole lot to help with. Good Luck.

I cant get any sound from my speakers only the subwoofer will work


Klipsch, usually fuse the speakers. look at the back of your speaker to see if there is a fuse holder, if not, it may be internal and if there is a panel you can take off, do that and look inside for a fuse and check it with a volt/ohm meter if its blown replace it with same value fuse. Aother way you can check to see if the speakers still work is to take a 9 volt battery and touch the terminals of the battery to the terminals of the speaker, if you hear a clicking sound or better yet can see the speaker move in or out the the speaker is good and the problem is elsewhere in your system. if both speakers don't work I would first suspect the fuse in the speakers. you could also try hooking up different speakers to your amp and see if those work, one last thing, plug in some headphones, if they work you will know that at least that part of your amp works.

How do you get access to the 1.6a fuse


I found this online. I didn't write it, I didn't try it, but it sure sounds good. First off, I had same problem with an old LifeStyle Series 12 and trying to get in to that case is like trying to get in to Fort Knox... I found these answers on a forum.. I wanted to let you know I didn't not discover them myself but it worked for me.. Also my fuse was bad... I am off to the electrical supply house as soon as I finish typing.. Without further ado:

OK Fellas (and Ladies), here's more detail on the blown fuse fix:
1. You can find the 'plastic swivel tab with notches' by looking for gear teeth in the top rear of the unit. To provide some context, I've placed the subwoofer with the serial number side down, horn is up-front and treble/bass dials on the left. Remove the dial knobs.
2. Now place the unit flat with the horn-side down. Literally use a tennis shoe to spank the plastic cover (on the same side as the gear wheel) in a 45 degree upward motion so the RCA plug holes in the plastic cover are dislodged from the jacks and the unit pops off. One good spank does the job *hee hee*.
3. 2 screws will be visible at the top of the green circuit board. Unscrew these and remove cable ribbons that attach circuit board to other pieces of the unit.
4. The fuse is a cylindrical glass piece, 5mmx20mm. Mine was burnt and coils were missing, an obvious sign of a blown fuse.
5. Don't go to radio shack to find a replacement. They are seriously under-equipped to assist. Go online or to a real electrical supply store to get a 3Amp, 250 Volt 5x20mm slowblow fuse. Don't try to call Bose either because this will inevitably result in more pain. They will try to coax you to order an owner's manual for $10 to get the part number, so you can pay an inflated rate to get the same piece from them. Grrr.
6. I saved $200 - thanks to all contributors on the board. Good work.
7. If this advice helps you, do something nice to help a homeless or mistreated animal. Humans can never be too kind to the rest of the creatures on this planet


Holy ****!!

OK, Bose owners out there listen up and listen good. Here's the real scoop on 1.(getting access to the inside of most bose subwoofers, 2.( repairing said subwoofer.

Follow these steps in removing the cover of your subwoofer. Unscrew the two screws from the cover. (They are on the input/output side of the cover) Remove the two knobs (Bass and treble volume). On the opposite side of the cover, (put those damn shoes back in the closet) there is a lockout tab that needs to be swung out, it moves 90 degrees in a counter-clockwise direction and is located under the center of the cover. A small flat blade screwdriver works great for swinging this tab out and will be necessary for the next step (the screwdriver that is). On the same side (opposite the input/output side) there are two small tabs near the edges of the cover, one on the right and it's counterpart on the left. If you look closely in the gap between the cover and the sub itself, you will see these 3/8" wide tabs near the edges and towards the top of the cover. With the flat blade screwdriver, put the blade between the cover and on the tab and pull down. Then with your hand balled into a fist, gently hit that side of the cover towards the input/output side. the cover will move only slightly but the tab should remain depressed. Do the same procedure on the opposite side of the cover and it will slide about a 1/2 to 3/4" towards the input/output side and can then be removed by pulling it straight up and off of the cabinet.

Yay! If you get this far without incident then you are ready to implement repairs. In the case of the AM15's, normally what happens is a resistor will open up and prevent the triac (turn-on device) from firing. The fuse is on the underside of the PC board and this above mentioned resistor is a 100 ohm, surface mount "chip" resistor on the top side of the PC board. It will not appear to be bad but trust me, if the fuse is good and the sub will not turn on... replace it! You don't have to use a chip resistor since as a consumer you may have a rough time finding one but a 1/8 watt or 1/4 watt resistor you can find at any Radio Shack will work just dandy in this application. Cut the leads short and solder the two cut leads to the pads on the circuit board where the chip resistor is currently sitting. The chip resistor will be black, about 1/4" long, 1/8" wide and have "101" printed on it's surface. On some models they used two 200 ohm resistors in parallel but the result is the same. One 1/4w axial lead resistor will do just fine. Plug it up and give it a try. (Before you replace the cover).

Secondly, if the fuse is blown on a "Lifestyle" Bose subwoofer, contrary to popular belief, it blew for a reason. The speaker outputs and the subwoofer output devices are TDA7294 IC's with TIP142 and TIP147 Motorola transistors used as current supplements to these said output devices. If the fuse is blown and replacing it only results in another blown fuse then chances are good that one or more of these are blown. In some cases it's very easy to tell, the front of these IC's will be blown off and/or you will see burn marks on the board where they are mounted. These devices are located inside the amp portion of the subwoofer. (The black metal heatsink underneath the input/preamp PCB. As a consumer, if the fuse is blown, unless you are familiar with soldering techniques and troubleshooting electronics, leave this to the pro's. It isn't as easy as you might think and you can destroy the PCB in your attempts to repair it.

On Lifestyle 25II and Lifestyle 30II systems there is a problem with the surround portion of the sub system. Inside on the surround PCB there is a 400 MHZ crystal that clocks converted (to digital format) audio signals through the surround processing area of the sub. These crystals fail and the system, although it powers up just fine, has no output at all or it is intermittent
