Hi, I have a two year old SoundTouch 300 sound bar and I went to use it yesterday and it wouldn’t turn on. I tried several things including unplugging it overnight, taking the cables out and reconnecting them, I tried a factory reset, a software update, pressing the SoundTouch button and the teletext button at the same time etc. but none of these worked. Unfortunately the bar won’t turn on or connect to WiFi or blue tooth, so I can’t connect for updates etc
I am sorry that your SoundTouch 300 no longer appears to be powering on. Thanks for already trying some great troubleshooting, I would like to do what I can to help.
Do you get any LED indication at all on the front of the soundbar? If so, what does it state?
I look forward to hearing from you.

My SoundTouch 300 did the same thing on Friday. It is just over 2 years old. Will not power on & No lights displayed on front panel. Can you order the power supply board (748871-0020) & motherboard (748866-0010) anywhere? Or straight from Bose? Thanks
Sorry that you're also experiencing a power issue with your SoundTouch 300 soundbars.
