A grainy screen on a TV can be caused by a poor signal, which can be due to a number of reasons, including:
Weak signal strength: The signal from your antenna or cable provider may be inadequate.
Weather conditions: Thunderstorms and other weather conditions can cause poor signal quality.
Interference: Nearby appliances or other devices can interfere with the signal.
Here are some things you can try to fix a grainy screen:
Check your connections
Tighten any cables and connections, or try switching from WiFi to a wired connection.
Restart your TV
Perform a power restart or reset your TV.
Check your settings
Try turning down the sharpness, turning off motion smoothing, or selecting the right picture mode.
Check your software
Install any pending app updates or make sure you have the latest TV software.
Check for obstructions
If you have a satellite, check outside for obstructions. If you watch over-the-air channels, try moving your antenna.
