OK, so your Bose remote is set up for your TV. That's good. You still have to connect some kind of audio output from the TV and connect it to one of the inputs on the Bose. Then you must select the input button on the Bose remote that you connected the TV to. For more information, please visit my website at audioserviceclinic.com. Thank you.
when you bye the produte u get bill & take the bill & go to compny when bye the from the diler give u replcement if is your product in warrnty
he replace the hole your pro active 5.1 spaker set go & talk with him i have problem like this please replace tis system
If there was a traumatic high-volume event that preceded this problem, I'd guess the tweeter died.
If you can access the connections on the tweeter and you have an ohmmeter, you could disconnect the tweeter and measure across the the terminals. A shorted or open voice coil = dead tweeter. A measurement near the stated impedance is probably ok.
If you have NO ohmmeter, you could carefully connect the output of one amplifier channel directly to the tweeter and just scooch the volume upward slightly from silence while playing something with very little bass in it. If you hear it, the tweeter is alive.
The tar like sticky substance is the suspension of the speaker cone and there is nothing wrong with that. Its doping compound applied by the speaker company to damp the speaker ( Was it not always there? ) If the suspension has come off the bass notes will flutter, if not its some other problem. Play some music and put your ears near the tweeters flared horn to see if they working. Nearly 30% of your sound comes from the upper part and if you have damaged it there will be a volume drop. These speakers are quite complicated on the inside. It has two amplifiers, one for the woofer and one for the tweeter. It also has a digital sound processor. Any thing could be at fault, even a simple wrong setting.
Check the bronze-colored coil underneath the foam cover. Note whether it looks worn, burned, warped or distorted. This may be the cause of your sub sounding fuzzy or muffled, which means it needs replacement. Look at the fuse inside the speaker and test it if you know how. This is a likely problem that causes your sub to power up improperly, play sounds at about half the volume or intermittently fade in and out. If the fuse is discolored or shows a short, you'll need to replace it
1 TAKE THE MAINS PLUG OUT
2 Unscrew the fixing screws on the back. (just the outside ones)
3 Take the back off and turn the amplifier circuit board to face you.
4 About 2" from the left and about 4" from the bottom you will see a sort of tab. pull it off gently and widen the 2 prongs slightly.
5 Put the jumper tab back on and re fit the amp.
Speakers are working OK otherwise?
Do you get sound from headphone jack?
It's probably some pot control not turned up.
Is MAIN OUT turned up
Are speakers connected to monitor out or main out.?
Is gain for mic turned up?
Is there a MAIN OUT switch (on/off)?
Is there a MUTE control on the board?
the circuit board and amplifacation supply inside the sub are blow or shorted out.thus preventing any sound. the head phone jack works only because it is a bypass feature supported by the actual computer not the surround sound unit
This is probably correct as modern equipment uses electronic volume controls rather than potential dividers the range is normally biased towards the bottom end so there is lots of the range that is quiet and a smaller part that is loud.
Unless you find that at the top of the volume range the system does not seem to be loud then it is probably correct. It is not uncommon for modern equipment to clip at 80 / 90% of the volume range. Where as old style equipment with volume pots used to clip at arround 30% of the volume range as it gave the apperance there was loads of extra volume available. In fact all that happened if you turned it up louder was it clipped more and more.
