Need Plastic Cover for Halo-Lite

[azguy1878]

Im looking for the white plastic cover that goes on the Sylvania Halo-lite tv, like the one pictured, needs to fit a 20" screen. I dont think its going to be easy to find, got one of these sets but the plastic is cracked and a piece is completely detached from the rest of the plastic but present. Does anyone know where I can find one, or if it can be repaired? Thanks!!
