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.

SOURCE: tv wont respond to remote
is it the factory remote? if it is check to see if something is blocking the sensor on the tv, clean the sensors, if it is a universal remote alot of new tvs have codes that even some of the new universal remotes dont support. if thats the case you will just have to make do.

If new batteries did not fix the problem, then it means the problem is either from the remote or the TV.
You need to do some diagnosis to confirm the source of the problem.
Remote: Check the remote battery terminal, see if its not rust. Also, disassemble the remote, can check the connection between the terminal and the remote board, see if there is no disconnection of any kind.
If after checking and all seems well, then it means the remote is defective. To confirm, borrow a remote, test it with the TV. If it works, then it means you need to replace your remote. But if the remote you borrowed does not work, then it means the problem is from the TV and not the remote.
TV: There is a sensor in the TV that communicates with the remote. If this sensor is defective, the remote won't communicate with the TV.
The TV sensor might have loosed contact from inside of the TV or it maybe defective and need to be replaced.
So do the above troubleshooting and let me know if the problem is from the TV or remote. If problem is from the remote, you need to do a replacement. But if otherwise, let me knows as well.

Check on the back of the TV to see if you have a "remote in" port. It will look the same as a 3.5mm headphone jack. Unplug the TV and plug a pair of headphone into the port and then remove it. Do this several times to breakup any debris that may have gotten into it or corrosion that may have occurred in the port. If something is in the port it will disable the standard remote sensor on the TV.
