Sound goes off fleetingly every few minutes LG TV OLED65B8PTA

[Vikram Sud]

In the last few days my LG TV OLED65B8PTA suddenly drops the volume significantly fleetingly every few minutes. 

 

Am also hoping this isn't the start of the end of this massive investment I made a couple of years ago !!!

@Vikram Sud Is the issue with the internal TV speaker, or with an external AV amp (AV Receiver) or sound-bar?

Does it do this on all channels, or one particular channel?  When it happens, do you have to do anything, or does it return to normal volume on its own?

Do you have any other devices attached to the TV via HDMI or SCART/PHONO/RCA leads, or any USB devices? If so try removing them if not in use.

Do you have any Home Automation active (such as Amazon Echo, or Alexa, Google Home etc.), that might be able to control the TV in any way?

@td47 Oh thanks very much will try that. Did not think of it. I have recently installed a Google Home Device in a different room !!!
