Sorry if this has been covered before, but the search function is not working for me at the moment. A friend of mine just purchased a new Samsung HCN473W widescreen RPTV for $999.99 at Fry's. I am working on getting it calibrated and need to know how to disable SVM on this model. So far the picture also looks very grainy, but I have heard that Samsungs are very dirty inside and need a good cleaning, so hopefully this will clear up that issue. But I really need to know how to get rid of the Scan Velocity Modulation! Thanks for any info.
