This may indicate a backlight issue or incorrect input source. Try pressing the Source button on the remote to cycle through HDMI, AV, and TV inputs. If the problem persists, contact support.

How can I clean the screen safely?

Turn off the TV and let it cool. Use a microfiber cloth slightly dampened with water (no alcohol or cleaners) and wipe gently. Avoid pressing on the screen.

Can I mount the TV on the wall?
