Disassembly of the Xiaomi Mi Remote M1906G7G: instructions with photos and repair tips

Xiaomi’s M1906G7G remote control (also known as Mi Remote or Mi TV Remote) is one of the most popular devices for controlling TVs, media consoles and smart appliances of the Xiaomi ecosystem. Over time, even such a reliable gadget can fail: buttons stop working, the battery dies, or the remote falls into the water. In most cases, the problem is solved by disassembling and cleaning, but many users are afraid of damaging the fragile case or losing small parts.

This article will help you disassemble the Xiaomi M1906G7G remote without the risk of breaking it. We will describe each step in detail, from tool preparation to assembly, point out typical errors and give tips for diagnosing malfunctions. If you have never disassembled electronics, do not worry: the design of this remote is simpler than smartphones, and you can do this in 10-15 minutes.

Before you start, make sure the remote is the real problem, for example, if it doesn't respond to pressing, check:

• 🔋 Battery charge (the indicator on the remote must flash when pressing any button).
• 📺 Compatibility with the device (some Xiaomi models) TV require the remote to be tied through the settings → Bluetooth and devices).
• 🔍 IR transmitter purity (dust or dirt can block the signal).

1. Disassembly preparation: tools and precautions

You won’t need professional tools to disassemble the Xiaomi M1906G7G, but some tools are hard to do without.

• 🔧 Plastic blade (or mediator) - for careful separation of the body.
• ⚙️ Cross screwdriver (size) PH0 or PH00) — screw-in.
• 🧲 Magnetic substrate or container – to avoid losing small parts.
• 📸 Smartphone – for photographing the process (useful when assembly).
• 🧴 Isopropyl alcohol (70%+) Cotton swabs - for cleaning contacts.

Attention! Don't use metal tools to detach the body, they can leave scratches or damage latches. If you don't have a plastic blade, an old bank card will do.

⚠️ Warning: If the remote has recently been in contact with liquid, do not turn it on until completely disassembled and dry.

Before starting work, disconnect the remote from the device (for example, through the Settings menu). → Bluetooth and devices → Disable Mi Remote on TV This will prevent random commands during repairs.

2. disassembly of the body: step-by-step instructions with a photo

The Xiaomi M1906G7G body consists of two halves held together by latches and two screws.

Step 1: Removing the battery

Turn the remote over and find the battery compartment (CR2032 type) and carefully put the lid on the compartment with a plastic blade, which holds on two small latches, remove the battery and put it aside (or replace it with a new one if the disassembly is related to discharge).

Step 2: Separating the halves of the body

The halves of the body are fastened by 4-6 plastic latches around the perimeter. Start at the top (on the side of the buttons):

1. Insert a plastic blade into the gap between the halves of the Power button body.
2. Carefully lead the shoulder blade along the seam, alternately snapping the fasteners.
3. Once all the latches are free, remove the top half.

Important: Don't use excessive force -- if the body doesn't respond, make sure all the latches are snapped. Sometimes one of them stays locked.

Step 3: Extracting the fee

When you take the top lid off, you'll see a circuit board with buttons and an IR transmitter attached to the bottom half of the case with two screws (under the cross screwdriver), twist them out and carefully remove the board, holding it by the edges.

Note that the board has a flexible plume that connects the main part to the IR transmitter. Don't pull the plume, it could damage it!

3. Diagnosis of malfunctions: what can break?

After disassembling, check the board and buttons for visible damage, and here are the most common problems and their signs:

If the board shows signs of corrosion (green or white), use a toothbrush soaked in isopropyl alcohol for cleaning. After that, dry the board with a hair dryer (at minimum temperature) or leave it for a day at room temperature.

⚠️ Warning: Do not use acetone or solvents for cleaning – they can damage plastic parts and rubber pads!

4.Brushing and repairing button contacts

The most common problem with the Xiaomi M1906G7G is the oxidation of contacts under the buttons, which is due to moisture or natural wear and tear.

1. Remove the rubber pad with buttons (it is simply removed from the board).
2. Look at the contacts on the board and on the inside of the pad. The oxidized areas will be dark or green.
3. Moisten the cotton swab in isopropyl alcohol and gently wipe the contacts. Use an eraser (washing gum) for severe contaminants.
4. Dry the details for 10-15 minutes.

If the contacts are worn or damaged, they can be repaired with conductive glue (such as Contactol), apply a thin layer of glue to the damaged area and wait for drying (2-3 hours).

💡

If you don't have isopropyl alcohol on hand, you can use vodka (a fortress of at least 40%), but it evaporates worse, so it takes longer to dry.

5. Battery replacement and remote assembly

If the cause of the malfunction is a discharged battery, replace it with a new one (CR2032 with a 3V voltage).When buying, pay attention to the shelf life: old batteries can quickly discharge.

The assembly of the remote is in reverse order:

1. Put the board in the lower half of the body and fix it with screws.
2. Carefully place the rubber pad with the buttons, combining it with contacts.
3. Connect the halves of the body, starting from the top (from the buttons side), and click them.
4. Set the battery and close the compartment cover.

Check your performance: point the remote to your smartphone camera (turn on the shooting mode) and press any button. If the IR transmitter is working, you will see a glimmer of purple light on the screen.

💡

If the buttons are tight or sticky after assembly, check if the rubber pad is properly installed, and sometimes it shifts and blocks the mechanism.

6. Common mistakes and how to avoid them

Even experienced users sometimes make mistakes when disassembling the Xiaomi M1906G7G. Here are the most common of them and ways to prevent them:

• 🔨 Broken body latches - occurs when using metal tools. Always use a plastic shoulder blade.
• 🔋 Short circuit: If you forget to remove the battery before cleaning the alcohol!
• 📱 Loss of screws or gaskets – work on a light surface or use a magnetic substrate.
• 💧 Incomplete drying - if you put the remote wet, the contacts will oxidize again.
• 🔄 Incorrect assembly – if the buttons don’t work after assembly, check if the rubber pad is upside down.

If after disassembly the remote stopped turning on, check:

• The polarity of the battery (it must be set "+" up).
• Integrity of the IR transmitter plume (sometimes it departs when the board is not carefully extracted).
• Power button contacts – they could have oxidized or contaminated.

7. Alternative methods of control without remote control

If the repair is delayed or the remote is finally broken, you can temporarily control Xiaomi equipment in other ways:

• 📱 Mi Remote (available for Android and iOS) connects via Bluetooth and repeats the functions of the physical remote.
• 🖥️ Voice Assistant (like Alice or Google Assistant) – if your TV supports voice control.
• 🎮 Gamepad (e.g. Xiaomi Game Controller) – suitable for navigating the Mi menu TV.
• 🖱️ Mouse and keyboard – connect via USB Bluetooth (for Android TVs) TV).

To connect an alternative remote via Mi Remote App:

1. Download the app from the App Store or Google Play.
2. Turn on Bluetooth on your smartphone and TV.
3. In the app, select the device type (Xiaomi TV) and follow the instructions on the screen.
