Recently l have had a few weird occurrences. My tv that l bought last year has been working great but the past few months something odd has been happening. I would have the tv on low and l would leave the room for a few minutes and all of a sudden l would hear the tv full blast. I go back to the room and the tv volume goes down to the level l had it on. I have checked the wiring and everything is fine. This only happens when I'm not in the room and no one else is in the room either.
I do not know what is happening.
It could be due to an "intermittent fault" on the tv...

The most likely cause is a "dry joint" on the sound board in the tv....

It is also possible it could be a component (capacitor, resistor etc) that is overheating, after the television has warmed up/been on for a while
