• 🚫 Alcohol and alcohol-containing solutions – even at a concentration of 30%, they can damage the microlayers OLED-matrices, causing pixel burnout.
• 🚫 Paper wipes or towels – their fibers scratch the surface, leaving microcracks.

• 🧹 Soft brush (for example, for makeup) or vacuum cleaner with a nozzle for furniture (power not higher than 300 W).
• 🧴 Wet wipes for equipment (without alcohol) or a solution of water with soap (1 drop per 100 ml).
• 🔌 Toothpick or plastic spatula to remove dried dirt from ports.

Procedure:

1. Turn off the TV and remove it from the wall/stand (if possible).
2. Vacuum the air vents on the back at minimum power. Keep the nozzle at a distance of 2-3 cm from the body.
3. To remove dust from HDMI, USB and other connectors, use a dry toothpick or compressed air balloon (such as Air Duster). Don't blow with your mouth - saliva contains acids that can oxidize the contacts.
4. Wipe the body with a wet wipe, then wipe dry. For glossy surfaces (such as Mi TV Lux), use polyrene for plastic without silicone.

⚠️ Note: If your Xiaomi TV has built-in speakers on the front (like in Redmi) TV A Series), avoid getting liquid into the perforation. Moisture can damage the speaker membranes, which will lead to distortion of the sound.

For models with Ambilight backlight (e.g. Mi) TV Master - Pay special attention to cleaning LED-The dust on the back can cause overheating and uneven glow. Use a dry brush or vacuum cleaner at minimum power.

Cleaning ports and connectors: how not to damage contacts

HDMI, USB, 3.5 mm and Ethernet connectors are the weak spots of any TV. Dust and contact oxidation can lead to signal loss or overheating of ports. Clean them at least 1 time every 6 months, especially if the TV is in a dusty room.

What you need:

• 🔌 Compressed air cylinder (e.g. Office Depot Duster).
• 🧷 Cotton swabs (better with a plastic base, not a wooden one).
• 💧 Isopropyl alcohol 90%+ (Only for contacts, not for plastic parts!).
• 🧲 Magnetic screwdriver (for models with screw ports mounts).

Step-by-step cleaning:

1. Turn off all cables from the TV.
2. Blow the ports with compressed air in short pulses (distance 3-5 cm). Do not tilt the balloon - this can lead to the release of liquid.
3. For persistent contaminants, moisten the cotton swab in isopropyl alcohol and gently wipe only the metal contacts (without touching the plastic walls of the connector).
4. Allow the ports to dry for 10-15 minutes before connecting the cables.

Gum or plasticine:

1. Put on the ice in the bag for 10 minutes to harden the mass.
