Problem: Sound is Present but No Picture on TV

Primary Causes of the Picture Problem:

1. HDMI Connection Issues: Problems with the HDMI cable or its connection point can result in the TV not receiving the video signal properly.
2. Power Supply Problems: Power interruptions or errors in power cable connections can lead to a situation where only the audio works while the video is disrupted.
3. Cable Connections: Loose or faulty cable connections that transmit the video signal can trigger this problem. Additionally, extra cables can significantly reduce signal levels, especially with multiple splitters.
4. Satellite Dish Movement: Users with unstable antenna placements might experience this issue due to varying weather conditions, especially during strong winds or snowy weather.
5. LNB (Low-Noise Block) Issue: Incorrect configuration or LNB displacement can cause this problem, often related to windy conditions.
6. TV Settings: Incorrectly configured settings or wrong input selection can result in sound without a corresponding image.
7. Update Problems: Issues during software updates can disrupt the proper functioning of the device.
8. Backlight Issues: Problems originating from the backlight can lead to a screen without a visible image.
9. LCD Panel Malfunctions: Issues with the LCD panel can result in a loss of image.
