SOURCE: got a blue vertical line on me plasma

I have done extensive reading and "Googling" about the - Blue Vertical line from top to bottom. (Oh so many problems and answers.) We are getting the shaft with these products: extended warranty or not. I have a 46 inch Samsung LCD TV (LNT4671F). I bought it 11/2007. Problem: I have a 2.5 inch wide hazy blue vertical line on the left side of my screen. Answer: I have found the problem to be related with the following: when you change to a new TV channel there is (normally) a small rectangular window that is a "channel display window" of the channel you switched to and some information, then it shuts off, and then you have a perfect viewing screen w/o blue line. When this "channel display window" comes on; I have noticed there is a vertical blue line - exactly 2.5 inches wide - which is exactly the same as my vertical line problem. I took the back case off and looked at the component at the top middle of the TV inside. I put everything back together, and then, turned the TV back on. Where there was a vertical blue line from top to bottom...now it is gone. One thing which is different --> I did not have this function set up before; the "channel display window function is now ON" whereby, previously, I believe I shut it off. Important: since the display window is back on (which shuts off in 10 to 15 seconds) --> I don't have a vertical blue line anymore !!!!
:) Very happy right now. If I called a service rep: they would have sucked lots of cash out of me b/c as customers ... we know little about how to fix this S_it.

This is a result of faulty or dying dip i.c.'s on the tv's logic board.
there are several that span the width of the tv, when one goes faulty it results in a vertical line.. often yellow.
the logic board is most likely small, containing at least 1 big chip wich is the micro... contact tv manufacturer and try to get a replacement. if not there are many 3rd party supplyers of oem parts
