Owners of Xiaomi Mi TV and Mi Box smart TVs often face a situation where the remote control stops responding to commands or starts to βglut.β The cause may be moisture, dust, spilled liquid or just wear of conductive rubber. Instead of buying a new accessory, many users prefer to disassemble the device to carry out cleaning or simple repairs.
The process of disassembling modern Xiaomi remotes, especially models with voice control and Bluetooth, requires accuracy and understanding of design. Unlike older IR panels, it uses more complex mounting mechanisms and delicate plumes. Incorrect opening can damage internal components, so it is important to strictly follow the sequence of actions.
In this article, we will take a detailed look at how to safely disassemble the Xiaomi remote, what tools you will need and what to pay special attention to when working with microelectronics. You will learn about the nuances of dismantling various modifications and ways to restore the device to work.
Tools and workplace preparation required
Before you start, you need to have a good lighting workspace, you need a clean, flat surface, covered with soft fabric, so that the small parts and screws do not get lost and scratched, and the absence of static and dust is the key to successful disassembly of electronics.
Xiaomiβs standard remote usually doesnβt require complex hardware to open the case, but the availability of specialized tools will make it much easier and reduce the risk of plastic damage, with a thin plastic blade or mediator that will allow the latches to be unscrambled.
- π§ Set of screwdrivers (cross-haired) PH0 or PH00) β screw-up.
- π‘οΈ Plastic blade or mediator - to open the body around the perimeter.
- π§Ή Compressed air or pear β to remove dust from the inside.
- π§ͺ Isopropyl alcohol and cotton swabs - for cleaning contacts.
Importantly, the use of metal objects such as a knife or a stiletto to tamper with the body is strongly discouraged.The metal easily leaves deep scratches on glossy plastic and can damage internal plumes or boards when moved carelessly.
Features of the design of Xiaomi remotes
Xiaomi's remote controls fall into two main types: classic IR models and modern Bluetooth voice-controlled versions. The former are as simple as possible and often have no screws, assembled exclusively on latches. The latter have a more complex internal layout.
Inside Bluetooth remotes like the Xiaomi Mi Remote or Mi Voice Remote, in addition to the infrared diode, there is a Bluetooth module and a microphone, which requires more careful handling, since damage to the microphone or antenna plume will lead to loss of voice search functionality.
β οΈ Note: In some Xiaomi remotes, the battery compartment may be sealed or have hidden screws under the stickers.Do not put too much effort if the case does not open easily.
It's also worth considering the body material. Most models are made of matte or glossy. ABS-It's a plastic that's quite fragile at the break, and with prolonged use, plastic can become even more brittle, so heating with a hair dryer (light) sometimes helps make joints more elastic before opening.
Step-by-step instructions: how to open the body
The disassembly process begins with the removal of the batteries, remove the batteries to avoid short circuits and free up space inside the compartment. Carefully inspect the battery compartment: in some revisions, the screws may be deep inside, under the contact spring.
If there are no visible screws, we'll go to find hidden attachments, and often one screw can be hidden under a factory sticker or a decorative stub at the bottom of the remote, carefully put the sticker with a needle, and if there's no screw underneath, put it back in place to avoid damage.
βοΈ Preparation for disassembly
The main step is to separate the halves of the body, insert the plastic blade into the joint between the top and bottom of the remote, starting at the bottom end (near the hole for the bald or battery compartment), smoothly drive the blade along the side faces, listening to the clicks of the opening latches.
Don't try to open the remote from one snatch. Walk around the perimeter 2-3 times, gradually increasing the gap. When all the latches are snapped, the halves of the body will easily separate. If you feel strong resistance, you missed the screw or the latch.
Diagnostics and cleaning of internal components
When you open it, you'll see a circuit board with contact pads and a rubber matrix with buttons, and most often the problem with broken buttons is oxidizing the contacts or contaminating the conductive surface of the rubber.
To clean, use a cotton swab lightly soaked in isopropyl alcohol. Gently wipe the graphite tracks on the board and rubber-based feedback contacts. Isopropyl alcohol evaporates quickly and leaves no trace, unlike water or other solvents.
| Problem. | Possible cause | Method of decision |
|---|---|---|
| The individual buttons are not working. | Contact contamination | Alcohol cleaning |
| The remote is off. | Oxidation of springs | Cleaning the springs |
| The buttons stick | Got a sticky liquid. | Full rubber wash |
| Weak signal. | Settled battery or IR diode | Replacement of elements |
If the rubber matrix has lost its elasticity or the conductive layer has worn off, you can use a special conductive lacquer or stick pieces of foil on the inside of the buttons. This is a temporary solution, but it often helps to extend the life of the accessory.

Specifics of disassembling Bluetooth models
Disassembly of voice-controlled remotes, such as the Mi Voice Remote, has its own nuances, and there is often an additional plume inside them that connects the main board to the microphone or additional sensors, and when you open the case, you can not sharply dilute the halves over a long distance.
And these models can also have a quartz generator and a more complex circuit, and the dust is less scary than IR panels, but the moisture is critical, and if you've been in water, you don't just have to dry it, you also have to wash the board with ultrasound or alcohol to remove corrosion.
When assembling a Bluetooth remote, it is important to properly stow the antenna (often wiring or spraying on the case) so that it is not clamped with plastic parts, which can significantly reduce the range and stability of the connection with the TV.
Assembly and testing of the device
The assembly is done in reverse order. Make sure the rubber matrix is flat, smooth, and all the buttons fall into their holes. When you connect the halves of the body, first snap the corners, and then walk around the perimeter, pressing your fingers until the characteristic click.
If you have screws in your design, twist them, but don't pull them over. Plastic in the screw attachment can crack when you're overforced. After you build, insert the batteries and check all the functions.

If the remote is unstable after assembly, try to remove the batteries for 5-10 minutes, which will allow you to reset the residual charge and restart the device controller.
Check the IR port through your phone's camera and Bluetooth connection in the TV menu, and if all functions are restored, then disassembly and cleaning have been successful.
Frequent mistakes in self-repair
One of the most common mistakes is to use aggressive chemicals to clean: Acetone or solvents can melt the plastic of the case or damage the labeling on the board. Use only specialized means or isopropyl alcohol.
Another mistake is the loss of small parts. The screws in Xiaomi remotes can be of different sizes (although rarely), and by confusing them, you can damage the thread or break through the case.
β οΈ Warning: Do not use water to wash the electronic circuit board. The water causes contact corrosion that will manifest itself in a few weeks or months, permanently disabling the remote control.
Also, don't ignore the state of the batteries. Oxidized or leaky batteries can damage the contact springs inside the remote, and if you find traces of electrolyte, they need to be thoroughly cleaned to a metallic shine.

Proper and accurate disassembly of the Xiaomi remote allows not only to clean contacts, but also to extend the life of the device for years, saving money on the purchase of a new accessory.
