Use needle-nose pliers to straighten out the tin bracket as much as possible. It does not need to be perfect, but this helps with the alignment of the connector to the back of the tv cover.

Align the connector, ensuring the center pin can reach the the spot on the board where it needs to be re-connected.
Solder the barrel of the connector to the metal bracket first, try not to let it get too hot. You may want to use a solder gun with dual heat of at least 50 watts for this part.
When that's done don't forget to solder the center pin to the board using as little solder as possible, to ensure there's no grounding to the metal cover.

Carefully replace the plastic cover. Replace cover screws.
Repairing is more environmentally responsible than disposing of a TV in a landfill. You are saving the environment from the Lead (Pb) glass from the rear of the CRT and Barium (Ba) glass in front screen.
There is very little danger of the CRT imploding or cracking if you use common sense, they are built for shipping and rough handling. The cadmium in the screen is unlikely to escape even during breakage, and is not much of an environmental hazard.
