4. Disconnect External Devices (HDMI Issue)
Connected devices like decoders, gaming consoles, or streaming sticks can control your TV.

This clears temporary system glitches.
Steps:

If the issue persists, reset your TV to default settings.
Steps:

If none of the above fixes work, the issue may be internal:

These require professional diagnosis and repair.
