I just replaced the color wheel on my Samsung 46" DLP. I appear to be having the famous color shadowing issue that has become synonymous with this replacement. I updated the CCA values (x,y) based on the sticker that came with the new wheel, but there were also Lv values that I was unable to locate in the service menu. As a result the color and shadowing still looks bad. Attached is the sticker that I received.
