Disassembly of the Xiaomi Mi TV remote: instructions with photos and nuances

Xiaomi Mi TV’s remote is a compact but fragile device that can eventually fail: buttons stop working, the battery runs out, or the body cracks after a fall. Instead of buying a new remote for 1,500-3,000 rubles, many users prefer to repair it themselves, but disassembly requires care: thin contacts, chips and tiny latches that are easy to break are hidden inside.

In this article, you will find step-by-step instructions with a photo on how to disassemble the Xiaomi Mi TV remote (including Mi TV Stick, Mi Box and standard remotes for Mi TV series 4/4S/5/5X/Q1/Q2). We will tell you what tools you need, how to avoid typical errors and what to do if the remote does not respond after assembly.

What tools are needed to disassemble

Before you start disassembling, prepare the necessary tools, without which you risk damaging the body or internal components.

• 🔧 Plastic blade or mediator to carefully separate the latch of the shell. Metal screwdrivers can leave scratches.
• 🔋 Screwdriver cross (PH0 or PH00) — for the spinning of screws (if you have them in your model).
• 🧲 Magnetic mat or container – so as not to lose small parts (screws, springs).
• 📸 Smartphone with camera - for fixing the location of buttons and board (useful when reassembling).
• 🧴 Isopropyl alcohol (70%+) Cotton swabs – to clean contacts if the buttons stick.

Some remote models (such as the Xiaomi Mi TV Remote Pro with voice control) may have hidden screws under stickers or rubber legs. If you are not sure about the screws, inspect the case for light - sometimes they are visible through the slits.

Preparing the remote for dismantling: important steps

Before disassembling the remote, perform several mandatory actions:

1. Remove batteries – even discharged cells can cause short circuits when in contact with the board.
2. Clean the case of dust and dirt with a dry cloth. This will prevent debris from entering.
3. Check the buttons – perhaps the problem lies not in the mechanics, but in dead batteries or contaminated contacts.

If the remote has fallen into water or liquid, do not turn it on until it is completely dry (at least 24 hours in rice or silica gel).

⚠️ Attention: Xiaomi Mi remotes TV 2020-2021 series (e.g. models) MDZ-26-DB) They often have glue joints instead of latches. They will require a hair dryer to disassemble them (heating to 60-70).°C for softening the adhesive) or thread/wire for cutting through the seam.

Step-by-step: how to disassemble the Xiaomi Mi TV remote

The disassembly process depends on the remote model, but the overall layout is the same for most devices.

Step 1: Rear cover separation

Put the remote control down on a soft surface (like a napkin), insert the plastic blade into the gap between the front and back of the case (usually near the battery compartment), carefully drive the blade along the perimeter, without undue effort - the latches should be snapped with a characteristic sound.

If the lid doesn't lend itself:

• 🔍 Check if there are any hidden screws (see photo below).
• 🔥 Heat the body with a hair dryer (only for adhesive models!).
• 🪡 Use two shoulder blades at the same time to evenly distribute the pressure.

Step 2: Extracting the fee

Once you remove the lid, you'll see a circuit board with buttons and a battery compartment. Carefully tuck the board on one side and lift it up. Pay attention to the plumes or wires (if any) that can't be pulled off! Most Xiaomi remotes only have the board on the latches, but voice-controlled models can have an extra microphone jack.

Take a picture of the location of the board relative to the body - this will help with the reverse assembly.

Step 3: Diagnostics and repairs

Now you can:

• 🧹 Clean the contacts of the buttons with alcohol (if they are oxidized).
• 🔧 Replace faulty buttons (you can buy them on AliExpress or in service centers).
• 🔋 Check the battery compartment for corrosion.
• 📡 Diagnose the IR transmitter (the LED should glow when you press the buttons - checked through the camera of the smartphone).

Frequent mistakes in disassembly and how to avoid them

Even experienced users sometimes make mistakes that cause the remote to break, and here are the most common ones:

1. Too much pressure on the body, it causes cracks or snaps of the latches, so you can use plastic tools and heat the glue seams.
2. Loss of small parts (screws, springs) Solution: Work on a light surface and use a magnetic mat.
3. Solution: Before disassembling, learn the mounting circuit (e.g., YouTube).
4. The wrong build, which causes the buttons to stop working, solution: take pictures of each stage of the disassembly.

⚠️ Attention: In the remotes Xiaomi Mi TV Remote Pro (voice-controlled) has a microphone module that is attached to the board with thin wires. If you're not handling it carefully, it can be easily torn off! If the microphone stops working after assembly, check the integrity of these wires.

💡

If the latches break during disassembly, they can be temporarily replaced with a drop of superglue (dot!), but such repairs will make the remote indissoluble in the future.

Xiaomi Mi TV remotes with an indissoluble body

Not all Xiaomi remotes are disassemblable, and some models have a glued body, and trying to open it will cause permanent damage, such as:

• 📺 Xiaomi Mi TV Stick Remote (models) MDZ-22-AB, MDZ-24-AA) — body glued along the perimeter, disassembly is possible only with destruction.
• 🎤 Xiaomi Mi TV Remote S2 (with touch panel) - the upper part of the body is glued, and the buttons are a single unit.
• 🔋 Xiaomi Mi TV Remote Lite (budget version) – often has rolled edges that cannot be separated without tools.

For such remotes, alternative repair methods:

• 🔌 Full replacement (cost - from 800 rubles).
• 🛠️ Repair without disassembly (e.g. cleaning contacts through a battery slot).
• 📱 Using the Mi Remote app on your smartphone as a temporary replacement.

💡

If your remote is a non-disruptive device, don't try to open it by force, it will cause a breakdown. You'd better go to the service center or buy a new one.

What to do if the remote does not work after assembly

If after disassembly and assembly the remote stopped responding, follow the following steps:

1. Check the polarity of the batteries – an incorrect installation can block the operation.
2. Examine the contacts on the board and the membrane of the buttons: they should fit tightly together.
3. Reset the remote settings (if it supports this feature). To do this, press the Menu + OK buttons for 10 seconds.
4. Check the IR transmitter through your smartphone camera (see spoiler above).

If the remote is still not working, the following problems may occur:

• 🔌 Breaking tracks on the board (needs soldering iron repair).
• 💧 Short circuit due to moisture intrusion.
• 📡 Damage to the IR LED (requires replacement).

In such cases, it is more advisable to contact a service center or buy a new remote, the cost of repairing the board may exceed the price of a new device.
