Hi, Im trying to turn on my home theatre but the subwoofer its on for a couple of seconds and it turn off automaticaly, the display it's on but the subwoofer its not. Coud you please tell me what to do.. Thanks. My address Sperez0416@rogers.com
Your cooling fan is not engaging and coming on like its suppose to. One, the fan is probably burned out, which sucks because its low voltage and the only thing on the board that is low voltage. Two, there is a thermostat type component that tells the fan to start which HAS burned out and doesnt start the fan accordingly. If you look at the back fan and turn everything on you will see the fan either doesnt start or starts right as the relay trips turning the sound components off. If it starts at all your fans good.The thermostat component will need to be replace and I cant recommend a source. Just trying to explain the problem so you can look for the right repair. Hope it helps. I have one of these and have found this is the problem, but cant find the solution.

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.
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.
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
If you have a "subwoofer-out" jack on the back of the receiver, you can put a y-cord on it and connect it to two powered subwoofers. Don't expect a big difference in the sound, however. You may even get less bass depending on where you position the sub-woofers.
hi the problem your having could be one of a couple of things the first to check is that all the speaker wires a fitted correctly and not come out of socket as a speaker wire shorting could give you the problem your having. The second and most likely problem is going to be a problem with the amp part of the circuit board usually a blown resistor but in your case as the unit comes on for few minutes then the chances are its just a solder joint failing on the board this causing the unit to trip out as a safety measure to stop it setting on fire. Check the sub woofer cable is fitted properly as this is the usuall problem with you make and model let me know when you have checked all of this ok
