Red bar/green bar on left side of vizio plasma

Question

Hi
I noticed you posted a response to my problem on fixya. We have two bars side by side on the left side of the screen. They're each about 1" and about 2" in from the left. Originally just a green bar appeared and would disappear for periods of time. Then the red appeared and it also disappears from time to time. We contacted vizio and they attempted to help in emails. They recommend either the TCP connector or the XRBT board. I have no idea what either are. The tv is only about 2.5 years old. Does their solution sound right? And is it worth fixing? Thanks a bunch
