Hey Tomwil, thanks for the reply,
Sorry for starting a new thread, most of the information I found when I searched was about the smaller plasmas. It seems that mine has 3 C boards (buffer boards?). Im assuming my middle one, C2, could be the problem. It is the same width as when I unplug any of the other buffer board connections, and when I unplug the problem segment it goes kind of white and black. The C2 buffer board part number is TNPA4618. I did a search of it and its only $25 on ebay. Does anyone have a Canadian vendor? the shipping kills me...
As for the horizontal lines, they are black and do not display the image. I am almost certain it is the connections however. I can push them in a bit harder and jiggle them around and more of the line segments will light up. Is there a trick to clamping them down properly and obtaining a good connection?
Thanks again for replying, if you can lead me to a thread with similar problems that might also be helpful. It may just be that the 58" tv's have a different board layout, because I can find similar information but not exactly what i'm looking for. Most of it pertains the 40 or so inchers.
