I replaced the Cluster Center LCD in my 2001.5 A4, I'm decent at soldering and when I hooked everything backup, I'm missing 6 vertical lines on the screen. I was told by the vendor of the screen that I probably screwed it up, so I took it apart, checked the solders, touched them all with some flux and 63/37 electronics solder, checked them and the same problem, no change at all.

Do you think the LCD is defective or did the cluster go bad in the repair?

Sorry for the horrible images but you should get the idea. The missing lines are visible even when the LCD is powered off via the stalk button, you can see shadows of where they are not "activated" or in any way powered.
