Question about Bose Cinemate 1 Sr Speaker System
Speaker worked fine when turned off. turned on again and red light started to flash and no sound.
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 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.

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.
