My emerson tv is acting weird. My remote does not work and the buttons on the front of the tv do not properly work. The power button works fine. However, the volume and channel buttons do not work. When I press the menu button it does nothing...however, if I hold down the menu button it turns the volume up. When I let go of the menu button the volume involuntarily turns itself down to zero (no volume). To make it even more odd, when I hold the menu button down and then volume goes up I can then hold down the volume button and it will "hold" the volume at its current intensity.
