Television Not Listed but still hopeful.

First id like to wish all here on this website a Merry Christmas

I have an

Westinghouse 46″ 120Hz LED HDTV LD-4655VX

which had no picture and i found the cable ribbon to one side of the light bar was not working. I replaced both but now one of the connector that the ribbons are slid into has come loose. I dont see how to reconnect it. Is it something a beginner can repair or am i out of my realm? Im unafraid to try! But not if its a no win. If anyone can give me a clue what to do id be Greatful!
