When your TV displays sound but no picture, begin by inspecting all cable connections, particularly HDMI, for security and damage. Verify your input source is correctly selected and the display settings like resolution are properly configured. If these steps don't restore the picture, try performing a power cycle by unplugging the TV for a few minutes. Additionally, examine the TV for any signs of physical damage to the screen. Should these initial checks not solve the issue, further technical steps involving the TV's internal components, such as the power supply board and the T-con board, may be required. Exploring these solutions provides a thorough understanding of the potential cause and how to address it effectively.
