It's hard to diagnose without a model, but, given the problem I would say it is a 42LC7.
If it is, then, it needs a modification in the main PCB. We used to jumper coils at first, now we have to change the main PCB.
It's less than a year old, it's under warranty.

The fault may be on the control board. Sometimes the button switches can be stuck, or there may be something causing some conduction on the control circuit board. It is also possible to have a component failure that is causing a continuous command to keep the volume to the high position.
Something that causes failures of controls in TV sets is when people clean the screen, they spray liquid cleaner on the screen. Some of it drips down in to the controls and on to the circuit board. This will usually cause damage, and thus the set will require shop service.
