I haven't worked on a Vizio but other loose RF connectors I've fixed just had to be re-soldered to the board.

I am referring to the coaxial connector. and I don't have any soldering skills, but it looks like removing a few screws and some wires would allow the entire board Name:  IMG_0581.jpg

to come off and be replaced.

If you were extremely handy you could fix it. It would require removing the top of the tuner box where the connector is located. The connector is held thru the metal box with a crimp. You may be able to see where the center pin of the connector solder to the board. There is a 50-50 chance it's on the top of that board.

You may be able to find a local TV repair place where they could fix that connector for you. I used to fix them all the time.

In case you can't fix it. The part number for that board is CBPFTQACB5K047. Be advised that some boards are sold with a dud return option so be careful not to destroy the board if you attempt to fix it. There are certain variations of that number you'll see on the board.
You can search online for the board by the part number.

Is vizio a good brand?

I'd say fix it. That board should be under $100.

I'm not sure how long the flat screen tv should last but my guess is a lot longer than the CRTs of old because there is not heat involved or high voltage. My guess is if nothing goes wrong in the manufacturing process, these things will last 10 to 15 years and you will probably replace it for a better functioning unit with more options before it goes bad. So, if you like the tv, have it fixed.
