Samsung, DLP TV 50 inches Model # HL-T5075X/XAA


Samsung just told me they wouldn't fix my tv because it was produced in Nov. of '06 and the only ones they would fix were made in August of '06 or earlier. I am way too angry right now to call the service tech number they so very nicely provided.

I have white dots on the screen of my hsl4266wx/xaa?


If these dots are only seen when the picture is on I would look for the Optical Block to be causing it. Are the dots in the same place each time you turn it on?
