I have the same issue with the subwoofer not working, googled it and sure enough found this thread. Less than a year old and it’s been doing it for a while, previously I would just power cycle the unit and the subwoofer would usually kick in on the second or third attempt. Now it won’t come on no matter what I do. I tried the reset mentioned earlier to no avail. THESE SHOULD BE RECALLED! Last Sony audio products Ii will be buying that’s for sure. STEP UP SONY!
Rest assured that there will be no recall. Products such as consumer electronic devices are only recalled for safety issues. Reliability, durability, and workmanship issues are covered under a warranty.
