I have my projector i sent in for warranty service and when i got it back i started noticing this odd noise in the video its a slight grain on moving brightly colored object, rather then a solid color, when I pause the grain is still along with the picture, but when the objest are moving the video noise starts moving too. what is causing this? I didnt notice this on the projector prior to send it in. now it has it, when I received it. Could it be the dvd player? if its the prjector I assume the grain would still be moving when the image is paused? could it be the dvd player? oddly none of this was an issue before sending it in. does anyone have the answer?
