I don't know if it is the focus or something else related to my dlp tv but the picture is grainy, blurry and the picture on the set actually seem to be jumping just a small amount but it is enough to make the viewing really annoying. This set has been doing this since I purchased it but the store keeps telling me it is the signal to the set that is causing it. Any suggestions other than deep sixing the set??????????????
Re: focus???problem on samsung hlp4674 dlp television
Try playing a DVD movie on the tv if you still get the same bad image your pretty sure that its a tv problem an you should get a hold of the manufacturer and let them know and see what they will do for you.. If the image has cleared up then it is a good bet that it is a signal problem. Good Luck !

Fuzzy is a funny word. I never use it to describe a picture problem. That because fuzzy can go too many different ways. There is snowy fuzzy, blurry fuzzy, grainy fuzzy, and demodulated fuzzy. If the set goes out of focus intermittently that has something to do with the focus ciruitry. If it goes grainy that is a front end problem, usually tuner related. The other types of fuzzy are generally associated with problems in video processing some where. So, which is it?
Oh, and BTW that unit has three small picture tubes in it, one red, one blue, and one green. It doesn't have a 'bulb'.
