- Sudden Turn Off: Check power control settings (Sleep Timer, Timer Power Off, Auto Power Off) and signal presence.
- 'No Signal' or 'Invalid Format' (PC connection): Turn TV off/on, reconnect HDMI cable, restart PC.
- Abnormal Display: Small "flicker" on cold startup is normal. Tiny black/colored dots (1 ppm) are normal. Brightness/color variations by viewing position are normal. Avoid prolonged display of still images to prevent image sticking.
- Generated Sound: "Cracking" noise from thermal contraction is normal. Electrical circuit humming/panel buzzing is normal.
Safety Precautions:
- Do not expose the product to rain, moisture, direct sunlight, high humidity, heat sources, steam, oil, or water containers.
- Keep candles or open flames away from the product.
- Ensure power cord is connected to a grounded AC mains socket and fully inserted.
- Keep power cord away from hot objects and heavy objects.
- Do not bend antenna cable between inside and outside building.
- Install wall-mounted TV with neatly installed and isolated cabling.
