It depends on the model of TV. In most cases, your solution is to take a toothpick and insert it where the button was. Push in on the toothpick (but make sure it's in the center of the hole) and you should be good.
There is another option, buy a universal remote. As long as your TV has a remote sensor, it should pick it up. Don't forget to program the remote to your TV though.
Between those two methods, your TV should be up and running in no time.

Click the Setup button to accept the selection then again to move to the Exit option. Click the down volume button.
