All inputs but ATSC tuner (coaxial) are dead on my plasma. How can I feed other signals through this input?

This 50" Panasonic from 2007 has lost all input functionality except the coaxial tuner input. Company says the board for the other inputs is dead and I don't want to spend the money to fix it.

What are my options? I'd like to be able to take a digital signal (VGA, DVI, HDMI, etc.) and convert them to coaxial so that the TV can display them through the tuner.

Yahoo Answers said I would be limited to an RF modulator with 480i output, but this tuner receives 720p HD signal from, so I don't think the 480i limitation is true.

What kind of device might I be looking for?
