Check if the TV is muted or if the volume is too low. Ensure the audio output settings are correct and verify that external speakers or sound systems are connected properly.
Ensure the power cable is securely connected. Check if the power outlet is working by testing another device. Try a different power cable if available. If the problem persists, contact customer support.

Ensure the input source is high quality. Adjust the picture settings by going to 'Settings', then 'Picture', and fine-tuning options like brightness, contrast, and sharpness.
Check that the HDMI cable is securely connected to both the TV and the source device. Try using a different HDMI cable or port. Ensure the source device is powered on and set to the correct input.
Turn off the TV and unplug it. Use a soft, dry microfiber cloth to gently wipe the screen. Avoid applying pressure and do not use any cleaning solutions directly on the screen.
Accessing the service menu is typically meant for technicians. It is advised not to enter it without professional guidance as it can affect the TV's operation.
