My model m3d47okd turns...

My model m3d47okd turns on, TV works but after hitting any button on the remote, the unit will not accept any other inputs, both with remote or TV. Have to unplug but the same thing will happen again. Only about 30 hours on it.

Technician's Assistant: Are there buttons on the side, bottom, or back of your M3D47OKD?

Back right lower when looking at the screen

Technician's Assistant: What menu options can you access, if any?

If I go to menu, it then locks up. Only on push of input.

Technician's Assistant: Anything else you want the TV Expert to know before I connect you?

One push
