Check the input source on your TV. Use the remote to cycle through the input options (HDMI 1, HDMI 2, AV, etc.) until you find the correct one.
Inspect the HDMI cable for damage. Try using a different HDMI cable or connecting the device to a different HDMI port on the TV.
If the above steps do not work, the display panel may need to be replaced. This involves disassembling the TV and replacing the panel, which is complex and may require professional assistance.
