SOURCE: LG 42LC7D-UB, Bad LCD Controller Board????

Steve, that was awesome. Thanks a bunch. I already have the tools and I can get the solder easy enough. Thanks a again. I went to Best Buy this weekend and all they could say is that the entire board would need to be replace and that they really recommended a new tv as the cost for the new board would be as much as a new TV.... :( typical of them!
