How to clean the Xiaomi Mi TV: screen, body and ventilation

Xiaomi Mi TVs with their thin bezels and glossy screens require special care – a common wet cloth or household chemicals can spoil the anti-reflective coating or even cause corrosion of contacts. In this article, we will discuss safe ways to clean both external surfaces and internal components (if you need disassembly). OLED- and LED-How to remove dust from the air vents without the risk of overheating, and why you should never use alcohol to clean the screen Xiaomi Mi TV Pro.

The manufacturer recommends cleaning the TV at least 1 time every 2-3 months, but in urban areas (especially with pets), it is necessary to do this more often. We collected proven methods that are used by service centers, and adapted them for home use. Importantly, the cleaning procedure for models Mi TV 4S, Mi TV Q1 and Mi TV A Pro has nuances – we will touch on them too.

Preparation: What will be needed to clean

Before you start, make sure you have everything you need, and the use of inappropriate materials is the main cause of divorce, scratches, or even touch button failures (in the Touch Panel models).

• 🧴 Special liquid for cleaning screens (for example, Xiaomi Screen Cleaner or analogues from the LG/Samsung). Distilled water with a drop of dishes is also suitable (but not the usual tap water!).
• 🧻 Microfiber wipe without pile (it is better to take a new one, as washed wipes can contain dust particles).
• 🪄 Soft brush with natural pile (to clean the vents) or a cylinder with compressed air (for example, Air Duster).
• 🔌 Antistatic spray (optional, to protect against dust after cleaning).
• 📏 Plastic spatula or mediator (for careful removal of dried dirt from the frame).

⚠️ Warning: Never use paper towels, toilet paper or wipes for cleaning - they leave micro-scratches. Also avoid products with ammonia, acetone or ethyl alcohol: They destroy the oleophobic-covering, which protects the screen from fingerprints in Mi models. TV 5 Pro and newer.

2. Remove the dust with a dry wipe. The movement should be light, from the center to the edges (not in a circle!). Pressing the screen can not be — this can cause burn-in (burning out of pixels) in the middle of the screen. OLED-panel.
3. Apply the cleansing liquid to the napkin, not the screen! Excess moisture can leak under the frame and damage the backlight.
4. Wipe the screen without pressing, then immediately remove the moisture residue with a second dry wipe.

For persistent contaminants (such as footprints from children's hands), use a charcoal pencil: gently stain them, then wipe them with a soft wipe. This method is safe for all types of matrixes, including QLED.

Cleaning of the shell and back panel

The body of the Xiaomi Mi TV is usually made of matte plastic or metal (in premium models), where you can use more aggressive methods, but with reservations:

• 🧽 Plastic surfaces will be fine with a weak soap solution (1 drop of the product per 100 ml of water). Apply it with a sponge, then wipe dry.

• 🕳️ Clean the air vents with a dry brush or compressed air. You can't use a vacuum cleaner, it creates static electricity!

⚠️ Note: If your TV has active cooling (fan like in Mi) TV ES2022), Do not direct the air jet directly into the holes - this can damage the blades. Keep the balloon at a distance of 10-15 cm.

Cleaning of ventilation and internal components

If the TV starts to overheat (it turns off on its own, the Overheat message appears), the cause is often dust in the cooling system. Deep cleaning will require partial disassembly. This section is only suitable for users with experience with electronics!

In Xiaomi Mi TV models, the fan is usually accessed through the back cover.

1. Turn off the TV and wait 30 minutes (capacitors can keep charge!).
2. Remove the lid by unscrewing the screws (usually the Torx T8 or Phillips PH1). In some models, the lid is held on the latches - use a plastic mediator.
3. Carefully remove dust from the fan and radiator with compressed air. Don't touch the board with your hands - static electricity can damage the chips.
4. Check the heat paste on the processor. If it is dry (dark, hardened), it should be replaced with a new one (for example, Arctic MX-4).

⚠️ Warning: If you're not sure about your skills, you should go to a service center. Incorrect assembly can lead to loss of warranty or short circuit. TV P1 and newer Dolby Vision system, sensitive to overheating - after cleaning, check the TV for 24 hours.

• ☀️ Avoid direct sunlight – it not only causes the screen to burn out, but also attracts dust due to static electricity.
• 🔋 Once every six months, wipe the case with an antistatic wipe - this will reduce the adhesion of dust.

In models with Google Assistant (such as Mi TV 5), you can turn on voice control to lessen the touch of the remote and screen, and it is also useful to turn off the TV from the socket during wet cleaning in the room, this will prevent dust from entering through the ventilation.

💡

Regular cleaning not only improves the appearance of the TV, but also prolongs the life of the matrix and electronics. Dust on the ventilation grilles can reduce the efficiency of cooling by 30-40%, leading to overheating and reduced resource. LED-lighting.

Frequent Mistakes and How to Avoid Them

• 🚫 Use of household chemicals (such as Mr. Proper or Cif) contain alkalis that corrode the screen's protective coating.
• 🚫 Cleaning the TV on, and besides the risk of electric shock, it can cause the matrix to deform due to the sharp cooling of the hot surface.
• 🚫 Pressure on the screen. OLED-This causes irreversible damage to the pixels (burn-in).
• 🚫 Ignoring ventilation. The accumulation of dust on the radiator accelerates the wear of the LEDs backlighting.
