I bought a Sony HT-XT3 sound-bar a couple years ago and rarely use it. Today, I thought of updating the firmware to the latest version given that its been a while. Connected to TV, internet then update.
After update, none of the options are working except for standby button and volume button. I contacted Sony and went through troubleshooting with them and none work. Now I’m stuck with this big paper weight. Just to let anyone out there planning to do updates on the old HT-XT3, don’t .
It's really frustrating that it’s Sony update that break the sound-bar, not because of hardware failure.
Did you even use the Chromecast built-in for audio?
Did you get an update failed message or did it just bricked itself during the process?
Maybe try an update via USB if you have some functionality.
