Disassembly of the Xiaomi TV remote: from the cover to the chip (Step-by-step with the photo)

Xiaomi's remote control panel stopped responding to presses, buttons stuck or battery suddenly discharged in a day? Don't rush to buy a new one - 80% of the time the problem is solved by cleaning contacts or replacing power supplies. You can disassemble the Mi TV remote in 10 minutes with just one screwdriver and a plastic card at hand. But there are nuances: for example, models with Bluetooth (like the Mi TV Stick) are understood differently than the classic IR panels for the Mi TV 4S/5X.

In this article, you will learn how to take a step-by-step look at photos, rotor layouts, fault diagnostic tips, and unique button compatibility data from different Xiaomi remote models, and how to avoid the most common mistake, which is damage to the battery compartment plume, which causes the remote control to stop turning on altogether.

1. What Xiaomi remotes can be disassembled independently

Not all Xiaomi remotes are disassemblable at home, such as the ultra-thin models for the Mi TV Q1/Q2 have a taped body, and the Mi TV Stick uses a non-dismountable remote with ultrasonic welding. Below is a compatibility table showing the complexity of disassembly:

If your remote doesn't fit in the table, check the model on the sticker under the battery compartment cover. The main rule is that if the case is glued (no visible seams or screws), disassemble it without special equipment is not worth it - the risk of damage to the fee is higher than 90%.

2 Tools and preparation: what is needed for disassembly

To disassemble the classic Xiaomi Mi Remote remote, you will need:

• 🔧 Screwdriver cross (size) PH0 or PH00 — small-rotor)
• 💳 Plastic card or mediator (to separate latches)
• 🧲 Magnetic substrate or scotch (so as not to lose screws)
• 📸 Smartphone (to photograph the location of details)
• 🧴 Isopropyl alcohol 90%+ (contact-cleaner)

⚠️ Warning: Do not use metal objects (knives, screwdrivers) to separate the latches - this leads to chipped plastic. If you do not have a plastic card at hand, take a guitar transmitter or even a bank card (mainly, it is inactive!).

Before the disassembly:

1. Remove the batteries and check their voltage with a tester (if <1.2V, replace).
2. Blow the compartment with compressed air (you can use a canister for the keyboard).
3. Take a picture of the remote from all sides – this will help with the reverse assembly.

3. Step-by-step disassembly: from cover to board

Consider the disassembly of the most common remote, the Xiaomi Mi Remote (black, with 12 buttons).

1. Removing the battery compartment cover Press the lock at the bottom of the remote and pull the lid up. If it doesn't lend itself, apply a plastic card on the side (but don't force - there may be a plume inside!). What if the lid isn't removed? If the lid is jammed, check if the lock is bent. Sometimes it helps to heat it up with a hair dryer (60°C) for 30 seconds, the plastic will become softer.
2. The sleeves are under the cover you will see. 2-4 The propeller (depending on the model) in Mi Remote they are usually 2 — twist them with a cross screwdriver and place them on a magnetic substrate. ⚠️ The screws in Xiaomi remotes are often of different lengths! Remember how much they come from - when you build it is critical.
3. Insert the plastic card in the seam between the halves of the case (starting with the battery compartment) and carefully guide it around the perimeter. You will hear clicks - this is the latches opening. Take your time: if the case does not disconnect, check if all screws are unscrewed.
4. When you disconnect the case, you'll see a board with buttons: 🔌 soldered to the battery compartment (in old models) 🔗 Connected by a plume (in new ones, for example, Mi) TV Voice Remote)

In the first case, carefully undo the contacts, in the second - disconnect the plume, pulling the black tongue (not the wires!).

4. Diagnosis of faults: what to look for inside

Now that the remote is disassembled, inspect it for typical problems:

• 🔋 Battery contact oxidation Green coating on metal sites is a sign of oxidation, clean it with a lastic or alcohol, if the contacts are badly damaged, they can be re-sold by soldering.
• 🎛️ Under the buttons is a rubber membrane with a graphite coating, and if the graphite is erased (seemingly transparent circles), the button will stop working, so you can apply a conductive paste (sold in radio stores) or replace the membrane.
• 📡 There's a little black LED (IR emitter) on the board, check it with a multimeter in diode mode: if it shows a cliff, it needs to be replaced. TV Stick) instead of IR, an antenna is used - its damage leads to complete loss of communication.
• 💧 If the remote is filled, the board will have white stains (salts). Clean them with alcohol and dry them with a hair dryer (cold air!) for 10 minutes. Don't use hot air - it will melt plastic parts!

⚠️ Warning: If the buttons are running "once again" after cleaning, the problem may be the chip. HT6P20B — You can buy it on AliExpress for ~$2 and replace with a soldering iron.

5 Cleaning and Repair: How to Bring the Remote Back to Life

The most common cause of malfunction is contamination of contacts.

1. Buttons and membranes Remove the rubber membrane and rinse it in warm water with soap. Rub it with alcohol and dry. If the buttons "fail," put a thin layer of foam (e.g., from packaging) under the membrane.
2. Pour the brush in isopropyl alcohol and walk gently through all the contacts. For hard-to-reach places, use a cotton swab. Don't rub with effort, you can wipe the tracks.
3. Blow the body with compressed air, paying attention to the depressions under the buttons. If dust accumulates inside, use a vacuum cleaner with a narrow nozzle.

If the button does not work at all, check its contact on the board with a multimeter:

1. Transfer the multimeter to "receiver" mode.


2. Touch the contacts of the button with probes.




3. Press the button - if the screen is "0" (or a beep), it is serviceable.

💡

To restore the graphite layer on the buttons, you can use a simple pencil: carefully shade the back of the membrane with them at the place of the erased contact.

6. Assembly of the remote: how to prevent errors

You need to collect the remote in reverse order, but there are 3 critical points:

1. In models with a plume (e.g. Mi TV Voice Remote), make sure that it is not twisted and fully inserted into the connector before clicking. If the plume is damaged, the remote will not respond to any button.
2. Tighten the screws cross-cross (like the wheels of a car) to keep the body flat. Don't pull over - the plastic can burst!
3. Before you finalize, put the board on the table, set the membrane, and press each button. If you have one, take apart the remote and see if any debris has been hit by the membrane.

After assembly:

• Insert the batteries and check the operation of all buttons.
• If the remote doesn’t respond, disassemble it again and check the polarity of the batteries – sometimes the contacts oxidize on one side.
• Bluetooth remotes may require re-pairing with the TV (press Home + OK for 5 seconds).

💡

If the remote works "once again" after assembly, the board is probably poorly fixed, take it apart and check if the contact is leaving somewhere.

7. Button compatibility: can one button be replaced with another?

Unique information for Xiaomi owners: the buttons in the Mi Remote and Mi TV Voice Remote remotes are the same size and pitch, which means that you can transfer a button from one remote to another if it is erased, for example, the Volume+ button from Mi Box S is suitable for Mi TV 4A.

Exceptions:

• Backlit buttons (there is in the Mi TV P1) – they have a different contact scheme.
• Google Assistant and Prime Video buttons are programmable and may not work when you transfer.
• Joysticks (in game consoles) - have a separate control fee.

If you lose a button, you can replace it with a similar one from other remotes (for example, from Redmi or even Samsung, if the size is the same), the main thing is that the height of the button is the same, otherwise it will stick.

8 When the disassembly did not help: alternative solutions

If after all the manipulations the remote does not work, consider these options:

• 📱 Use your smartphone as a remote Install the Mi Remote Controller app (official from Xiaomi) or Unified Remote. You need an IR port on your phone or a connection to work. Wi-Fi/Bluetooth.
• 🖱️ Connect the mouse/keyboard to any USB-The mouse or wireless keyboard will work with the Mi TV port USB-A. This is a temporary solution until you buy a new remote.
• 🔄 Buy original or universal remotes Original remotes for Xiaomi are worth ~1500-2500₽, Universal (for example, one for all) 800₽. Before buying, check compatibility with the TV model.
• 🔧 If the problem is in the chip or plume, the repair will cost in 500-1500₽. The service may offer to reflash the remote if it glips due to a software failure.

⚠️ Note: Universal remotes often do not support voice search and fast access buttons (such as Netflix or Prime Video.
