I fixed the blue line problem on my LG Plasma HGTV today after replacing a circuit board, but now Dale Earnhardt Jr’s car is orange!
After removing all of the screws holding on the back cover of the set, It took a while to figure out the easiest way to get the to board I needed to replace and remove the fewest wires and other components as possible. I ended up removing all of the wires on the rear-most panel except for the power connector lines that were located on the bottom right.
The board swung freely so that I could get my tools and hands behind the left side.
Replacing the board wasn’t a big deal except for the little swing connectors on the two wire harnesses at the bottom. After I figured out how they worked, it was easy, but I did break both of the ones on the old board trying to figure out how to get the wires out. Basically, it the locks are on a hinge and swing up and down. When down, they pinch the wires in the correct place.
I put the whole thing together and the sound was great, but no picture. After sitting there a while thinking about all of the wires I unhooked, I remembered one that I forgot to put back in place. After removing the back of the TV again and connecting the wire, everything worked great.
NOTE: Dale Earnhardt Jr. is driving an orange car this weekend.
