Definitely a blown fuse, you just need to locate it.
Look up the diagram for your make and model.

My experience with 42" plasma tv's with no picture or sound was a missing power supply voltage. On the power supply board check voltages on the plug. The voltages should be marked on the board,

Try resetting the TV by leaving it unplugged for an hour.
Plug it back in and check to see if it works normally.
If that doesn't work, rule out the Directv box by pressing the reset button near the access card. The box could be putting out a signal that doesn't have video or audio.
If everything fails, have the tech man come back to check everything that he did before you use the warranty on the TV.
