Hi Roger can you talk me through how the Bose sound bar is connected to your devices currently and how the DVD/set top box are connected to the TV.
Ok, and you get sound on the TV speakers when watching DVD' its just not being transmit via digital optical out?
It sounds like the audio processor has failed on the TV. as you have said you have already gone through the software settings and configurations it sounds to me like you have a hardware fault.
You wont get the sound quality your after but as a troubleshoot step I would look to plug the headphone jack on the TV into the Aux input 3.5mm jack on the soundbar, and check your getting sound for TV, DVD and set top box.
To be clear your still not getting sound from HDMI sourced?
This certainly points to a hardware fault with the TV, but would be inclined to leave it as is if the sound quality is ok, otherwise look to get the TV over to a repair engineer, as it sound like the main AV board needs replacing.
No problem Roger
