Press the cc button on your remote control. You want cc to be off. Play around with the cc button to become comfortable. Press it over and over again. Observed that a different closed captioning option appears on your screen each time you press the cc button. Now press cc and when it says cc off do not press the button anymore.

I had the same problem with a Sharp Aquos 40". Sound just for a second and the message all the time in the middle of the screen, no more sound.
I opened the TV and found a speaker cable (a black one) with the PVC isolation broken and the wire in contact with the chassis. I just isolated it, the sound came back and no more error message.

Did you go through the entire factory reset? When you plugged in the power cord did you continue to hold the volume - and input button until the television powered on and a K appeared on the screen never releasing at all?

Force the tv on by holding down channel down and volume + on the tv while plugging the tv in. See if the tv still lights up and if you get audio.

You may have PIP or picture in picture turned on and set to a input that has nothing connected to it. That's why the box is black. There should be a button on the remote for PIP. Try to turn it off. Or turnit off in the menu.

sounds like you might have PIP turned one (picture in picture) .. if there is no input hooked up for the PIP . you will just get a black screen ... you should be able to move that PIP around and change its size .. indeed turn it off .. look for a menu item called PIP .. select PIP off ..

did you check the sleep mode on the tv?

Have you check all inputs as the HDMI inputs and the composit inputs are processed on a different bd?

Try to replace the main digital board.
