I don't have any advice about repairing the SID, or "SAAB Information Display", on a SAAB 9-5 except to say that I only made mine worse by trying to make it better. There are several methods for DIY repair of missing pixels on the information display. I tried the foam spacer and warm iron methods and only ended up with more missing pixels.
There is a reputable company called BBA that will repair the SID and garentees its work.
SAAB Central has a thread about SID repairers that is worth reading before choosing a company.
My SID will be off to BBA soon for repair and I will post about the results at that time. For now, here are images from the inside of the SID for your entertainment:
