My tv model is HL 67A51J1F what I needs to do to fix the white dots on screen??
@zurdo69 white dots, snow or sparkling is usually caused by a bad DMD chip. On most models the DMD is replaceable, but your model number seems to be invalid. Check it again. Also, the white spots must be random and all over the panel. If they are symmetric and rather large, then it is not the DMD chip but possibly LED errors. Post some images of your screen with your question. For that use this guide. It will allow us to see what you see.
