I had the same problem with a 996 cluster that I swapped into my car. I couldn't find anyone willing to swap lcd's for me and I didn't think that I had the required skills. You can read about my experience here:

FWIW, the information provided to me indicates that the problem with the lcd's is caused by contaminants that get between the layers of materials during the manufacturing cycle. Time and perhaps temperature change eventually cause the layers to de-laminate and the result is what you see in the original post. This seems to make sense, but I have not seen any information from an official source confirming it. Considering that Porsche eventually adopted a dot matrix displays in lieu of lcd's seems to confirm that this was a flaw with the technology or manufacturing technique.

If anyone needs cluster programming instructions, send me a PM with you e-mail.
