Hi, I own a HTSS3455 Home Theatre system since 3 years and it worked without any complaints since then but since last month I am facing sub woofer issues ..when I increase the woofer base volume above 5 DB and increase the volume to MAX ...the system crashes and some IC's burn out in the woofer panel where the circuit board is present ..I got it repaired from the Philips authorized service people here..but when I repeat the same thing above it burns out..again I need to give it to them for repair. I do not think service peple are determining the correct diagnosis...I had checked all the wires going to the speakers and they are in shape as before and also I am using the same set of speakers connectors and wires which were supplied to me.Can any one help me as the same thing has repeated 3 times now. Regards G.P.Kumar

Well if it buzzes only for a couple minutes after turn on then it could be when the woofer starts pumping it produces pressure in the cabinet which creates a bonding motion that then closes the cracks, kinda like glue. Like blowing a balloon up in a box. The balloon is the pressure, OR Yes it could be your woofer is going bad. All speakers have voice coils. Tiny wire wrapped around a thin layer of cardboard then attached to the cone. This cone could be getting loose. But when the woofer heats up after a couple minutes it probably bonds the tiny wires so then the vibration or buzzing disappears. Over time woofers can die especially if it produces a lot of distortion, In a speakers life distortion kills and it doesn't matter how much power it can handle or how much money you spent on it.
Not all sub-woofers are alike. Some can handle the really low lows, and some can not. Check your settings too. Over time the vibration of the woofer will start to undo the glue, nails, screws, and even burn through the tiny wires in the voice coil. Oh and make your china crawl across the table... Have you been watching a lot more action movies? Some of the older woofers can't handle the newer digital deep bass frequencies... You may have to reconfigure your setup.

The sub-ts5 had glue that went conductive on the circuit board and when it is removed unit should work again a good tech should be able to fix this for you

I hope Bose has over 90 days warranty because you need to return that!

If the system uses a remote control, you may need to adjust the subwoofer out signal setting or turn on the sub in a menu, and on many systems, you can only access those settings via a remote control (you should check the onkyo user manual on how to do it).

Now, this is just one suggestion, it may work, but then again, it may not.

These could also be connection problems or some internal trouble in the onkyo sub signal output section or in the subwoofer input section, but hopefuly, it's just a "turn on" or "signal level" setting in a menu.

Good luck

hi,
steps to trouble shoot for sub-woofer detection :
1. please check whether the cord is securely connected at both the ends.
2. check if there is transmission through the cord (there'll be a small static through the cord if there is transmission.)
3. reset the dvd-player to default audio-output and then choose the 5.1 sound system which is the correct setting for the th-c6.
4. also check the settings in the th-c6 whether it is in 5.1 mode(whether it includes the woofer-as it can also simple use the stereo speakers)
5. now check the sound output in all speakers by playing any original home-theatre system enabled dvd.

the system will work perfectly if the cord is in good condition, otherwise please replace the cord again, and this time check it at the store.
cheers

As I found somewhere on the internet; there are two 470uF/25V capacitors on the power supply board in the sub-woofer that are the cause of buzzing, crackling and then eventually no sound. Go to Radio Shack and buy two Catalog #: 272-1030 470uF/35V capacitors and change them out. They are in the middle of the Power Supply PCB and are close to the long flat aluminum heatsink. Make sure you match the polarity properly when replacing. Your unit will be as good as new and will proibably last forever now.

buy new speaker cable for home theatre ;)

Actually...It has been the fact that speakers have a very minimal guarantee when compared to the other peripherals.This is a very common problem faced by many people.

What you are supposed to do is just replace each and every wire connected to your speakers with the new one.You can get the new wires from the market.That way your sub speakers will get fixed.

Coming to the woofer,just give it for solders check.There may be soldering problem inside the speakers.

This means that you have purchased a three piece home theatre system. Two tweeters and a sub-woofer. Assuming you are using a Stereo player (Tape/CD/DVC)you have to connect the Left Output of the Stereo placer to the Left Input at the back of the Sub-Woofer and the Right output to the Right input of the subwoofer by cables. Then take tweeters and connect them to Right speaker and Left speaker output at the back of the sub-woofer ( note if the speakers are marked L/R, then connect them to the subwoofer output accordingly. In case you are using a 5.1 player, then only connect the front right and front left to the Right and Left input at the back of the subwoofer. You are and you can now start playing your music or movies and and you will get theatre quality sound.
