Sony XBR- 65X900C - Model BRAVIA 4K 2015 - Version 7.0 - Android Security Patch Level May 1, 2019 the sound will just stop . Picture stays. Last night stopping after about 30 minutes of watching. The only fix is to turn off the TV . Wait a bit and then turn it back on. Software is updated - appreciate any help or advice. Henry
@pmcleod try an external speaker/soundbar/headphones and see if that makes a difference. Since you already updated the software etc. It is possible that this is an audio IC issue on the main board. Try a local input source like a DVD or BR to see if that works better. If so you need to check your video in source like cable box or sat receiver etc.
