Thanks! That second website was the most helpful one I found, as they give an explanation for the meaning of the service codes. I finally entered the service mode and managed to correct some stuff though I'm still getting the tech people out here on Monday. I will be curious to see whether THEY have any idea about what all the codes mean as I've seen responses now about this on various threads saying that few people really understand how to put all the convergence, alignment, etc. stuff in order. I guess it's like piano tuning--you can read it in a book but no sub. for experience.
