This is a powered sub-woofer, with a complementary sound bar. The amplifier for the sub and the sound bar, are in the sub cabinet. Because there are multiple speakers in the sound bar and sub, there are multiple amplifiers to run them. If any, or all of the amplifiers are damaged, they generally have a condition known as DC Offset. There are sensor transistors on each of these amplifiers, which will "report" a damaged amplifier condition back to a microprocessor(computer inside the Bose system). When this damaged condition is identified, the amplifier will shut down the system, and that red indicator will flash. You will need a professional, audio specific technician, as this is not a DIY repair.

If any of you are interested in having your systems repaired, please contact me from my website, audioserviceclinic.com. Just FYI, this is not a Bose specific issue. The same problem can occur with any amplifier, any brand. Thank you.

The damaged amplifier theory sounds reasonable to me. I ran the sound bar without the subwoofer for some months due to a lost cable (someone threw it out not knowing what it was!), but eventually it reached this condition (flashing red light, no sound). My theory is now that running the sound bar without the subwoofer damaged a sound-bar amplifier (which of course would be poor circuit design, but that happens). So now I probably need a replacement cable (>$50) AND a circuit-board replacement in the sound bar. Instead I think I'll choose electronics recycling and come up with a new idea for the living-room sound system. It is interesting that the flashing red light error is not listed in the Troubleshooting section of the manual. Poor!

    If the Bose system was working fine, but you now have a flashing red indicator, you probably are experiencing DC Offset, which is to say, your amplifier is possibly damaged. I'm quite sure if you look into your user manual, if will confirm my suspinions. For more information, please visit my website at audioserviceclinic.com. Thank you..

SOURCE: front bose speakers and bass module stopped puttimg put sound

If you're saying you hooked the Bose speakers directly to the Yamaha's amp instead of the prescribed way through their own bass module - they're cooked.

SOURCE: no sound from rear speakers on the lifestyle 18

The SL2 works in such a way that the speaker satellite out put from the bass modules is fed to the input of the SL2 transmitter (remember, transmitter) then the sattellitespeakers are connected at the other end of the room to the receiver. An initial blinking green light should be seen and once the system is turned on this turns into steady green. Both the SL2 transmitter and receiver operates via WIFI.

Glad to be of service...

I have also have this problem with a lifestyle 28 system. Bose sent me a new cable then a software update. The problem remained, after contacting Bose and unplugging cables and powering down the system this solved the problem. However 2 days after and the problem has re-appeared. Back to square one. I should add that this is the second unit I have had the retailer exchanged the last one because of the same problem.

My ps 3 was working fine and all of a sudden it went off. I tried to turn it back on and can on for a sec and then went off again. The light started flashing red.


Dear Friend,

The red flashing light might indicate and error with your PS3 console just follow this step to reset your console. This might help,

Press down the power button, you will hear one beep, keep pressing then, the second beep will sound twice. From there it will prompt you to the reset screen.

Good Luck!!

Receiver will not operate. when powered on red light flashes, menu displays, than thee is a loud click and the red light keeps flashing. tried the reset and it still does not work.


This sounds like the unit is going in to protect mode. See the link below for further information. Specifically to your unit, we need to know the model number. Also, try disconnecting the speaker cables completely and try again. Update this with how the unit reacts. If the unit powers up fine, then there is a problem with either the wiring to the speakers or the speakers themselves.

Please keep us posted.

Thanks,
Dan

I have a SONY KF-WE50 rear projection tv, a few weeks ago it started to turn the pic and sound off while the green light was flashing around 30 times. After the light finished flashing both the picture and...


the green is the reboot process and is normal.
the red light is an error code indicator.
count the blinks of the red light...it cant be 30 times (I think)
it will blink a sequence, pause, then do it again for a total of three times.
count carefully, it gives you three chances to catch the number it is blinking.

My Panasonic SC-HT995W keeps on flashing W and the rear speakers wont work. Ive tried turning off all other wireless devices but it still persists


I had exactly the same problem. My unit worked fine until a loose power cable resulted in the receiver being turned on and off a couple of times in quick succession and then after this the a/c in light on the rear speaker was lit but the wireless link light would not come on (and the 'W' on the main unit flashed constantly). The solution for me was basically a reboot. This is what I did;
- unplug the wireless receiver
- unplug the main unit
- remove the digital transceiver unit from its slot in the back of the main unit
- plug the main unit back in and turn it on - the 'W' won't flash as the transceiver has been removed (not sure if you if it's necessary but I made sure it was producing sound to the front speakers)
- unplug the main unit again
- reinsert the digital transceiver
- plug the main unit back in, turn it on and set it to produce output/sound (the 'W' will be flashing)
- then plug the wireless receiver back in again
...presto the link is made, the 'W' stops flashing and the rear speakers work again.

Hope this elaborate reboot works as well for you as it did for me.

Logitech Z-5450 5.1 surround sound speakers - no sound from rear right only


Unfortunately I have the same problem. As an electronic engineer I suspect that the power supply part of the unit is damaged. I opened up the module (don' t try it, its a little bit tricky since there is a type of glue around the silver bezel, after you remove the 4 screws from the front holes) and did some quick static measurements with a multimeter, so far no luck. Since I am still in warranty I will try to replace the item. Hint: protect your electronic equipment with ups or surge protection devices.
