I've been replacing an lcd display that goes into an Audi car. The display sits in the center of the dash and gives info about condition of car and info such as speed, mpg, eta stuff like that. I've been repairing auto electronics for 8 years now so I'm good at soldering but am kind of new to these lcd displays.
The display doesn't act right and I've installed 4 of them in this same car thinking I may have had some faulty displays as the first 2 I tried were Chinese made. I then bought some more expensive European made lcd displays and tried 2 of them only to get the same results.
Here's what the display is doing if you'll go to this link
This link describes the repair I'm trying to perform and as you can see, its pretty straight forward.

I've done about 4 of these repairs, had success on 2 of them and 2 of them did exactly what is being shown in the video. The 2 I had success on initially didn't work but on the second attempt, the screen worked fine so the odds of this being a bad instrument cluster is very low and I've had no luck trying to find Audi owners that had bad clusters so this is something I'm doing wrong but can't figure out what it is.
