Here is a little involved method that your dad will come in handy with.
First run out to your local Napa or Pepboys auto repair shop and buy all in one fiberglass repair kit.
Repair the crack on the back side of your bezel first by sanding it down to a rough area and then applying the Fiber and hardener. Use it sparingly because the bezel is very thin. And when you sand it down later you do not want to wear down the rest of the bezel.
Now that the crack is repaired lets work on getting your bezel to fit your TV. First get two Saw horses and lay your bezel on the saw horses so the inner curved part is pointing down. Sand throughly the outside the part you see that goes in towards the TV. Now cut the remainder of your fiberglass into strips about 6 inchs long or atleast three inchs past the depth of the inner bezel area. Now Dip your fiber glass strips in the harderner and start placing the strips around the inner edge so that they hang towards the floor. Basically extending the bezels inner depth and angle so it will hide the rest of the TV casing.
Once it is hardened and dry sand the complete bezel front and back. every last part. Sand until it is completely smooth the box might come with some filler puddy you can use on some of the really rough spots. If not then just add a little of the left over filler and cut a small piece of fiberglass to fit the divot. Then sand again.
Take your bezel to your tv and again with clippers cut the excess Fiber glass so it meshes upto your TV perfectly. Sand the edges down a little so you don't accedently scratch your TV.
Now that we have a completely sanded bezel grab a can of Black Spray paint. Gloss to match original bezel or Mat to cut down on bezel glare which is minimal anyway. Now paint your nice sanded bezel with a light coat so as to help from flex cracks in the paint.
Tada you have fixed your bezel! and learned somewhat how to fabricate a car

. Now I am waiting to see some fiber modded arcades
