How to Troubleshoot a Samsung DLP With White Dots
Samsung's DLP TV has two features that help you remove digital noise from your picture, such as white dots or snow. Weak signals often cause this effect. The TV’s signal-strength meter is used to measure a channel's signal strength, and the Low Noise Amplifier function boosts incoming signals. Use both features to obtain a noise-free display.
