Why Xiaomi TVβs curtain is failing and when itβs time to change it
The curtain (or mechanical shutter) on Xiaomi TVs is not just a decorative element, but a functional part that protects the screen from dust, mechanical damage and adjusts the viewing angle. Over time, it starts to jam, creak or stop closing altogether. If your Mi TV makes extraneous sounds when it opens / closes, gets stuck halfway through or does not respond to commands from the remote, these are sure signs that the mechanism is worn out.
The average life of a curtain is 3-5 years with heavy use (daily opening/closing). Wear is influenced by several factors: temperature changes, humidity, dust entering the guides, as well as mechanical stress (for example, if children pull the curtain manually).
Before you run to the service center, assess the condition of the curtain according to these criteria:
- π Noise at work - creaking, cracking or humming of the engine.
- β³ Slow motion β the curtain opens/closes for more than 5 seconds.
- π Blocking β stops halfway or fails to respond to commands.
- π Arbitrary operation - it opens / closes itself without pressing buttons.
β οΈ Warning: If the curtain is stuck in the closed position and the TV is not turning on, do not force it to open! This can damage the engine or the belt of the drive. First turn off the power and check if a foreign object has entered the mechanism.
What curtain to choose for Xiaomi TV: compatibility and models
Not all curtains fit all Xiaomi models. The main criteria for choosing are screen size, type of mount and mechanism version. For example, for the Mi TV 4S 55" and Mi TV Q1 55" different models of curtains are used, although the diagonals are the same. To make no mistake, check:
- Model TV β Look at the sticker on the back (like the L55M6-6ARU).
- The original curtain article usually begins with MDZ- or MJD- (Indicated in the documentation or in the old detail).
- The type of drive is motor (automatic) or manual (only for budget models).
The table below shows the compatibility of curtains for popular Xiaomi models (currently for 2026):
| Model TV set | Diagonal | Articulum of curtains | Type of drive | Notes |
|---|---|---|---|---|
| Mi TV 4S | 43" / 50" / 55" | MDZ-06-055 | Motorized | Suitable for versions 2019-2021. |
| Mi TV Q1 / Q1E | 55" / 65" / 75" | MJD-08-065 | Motor (with sensor) | There are new guides in the set. |
| Mi TV P1 | 55" / 65" | MDZ-07-055 | Motorized | Requires firmware after replacement |
| Redmi Smart TV X | 43" / 50" / 55" | MJD-05-050 | Manual/motor | There are versions with plastic and metal belt |
If you can not find the original curtain, you can consider analogues from third-party manufacturers, for example, Baseus or Remax. The main thing is that the size of the mounts and the connector of the motor (usually a 4-pin or 6-pin connector). Before buying, check the reviews: some non-original curtains may not work correctly with Xiaomi proprietary software.
Preparing for replacement: security tools and measures
Replacing the curtain is not the most difficult process, but it requires care.
- π§ Screwdriver (cross, size) PH2).
- π Plastic mediator (for disassembling the body without scratches).
- π§² Magnetic screwdriver or tweezers (so as not to lose the screws).
- π§΄ Alcohol wipes (for cleaning guides).
- π Multimeter (optional, to check the engine).
Before starting work, it is mandatory to:
- Turn off the TV and wait for the full discharge of the capacitors (10-15 minutes).
- Place the TV screen down on a soft surface (such as a towel).
- Take a picture of the location of the screws and connectors - this will help with the reverse assembly.
β οΈ Attention: If your Xiaomi TV If you have a warranty, if you change the curtain yourself, you can cancel it, and then you should go to an authorized service center, and you should not disassemble the TVs from the curtains. OLED-screens - the risk of damage to the matrix is higher.

Step-by-step: how to remove the old curtain
The dismantling of the Xiaomi TV starts with the removal of the back cover.
- Remove the stand (if installed). To do this, unscrew the 4 screws on the back panel.
- Disconnect the back cover: Start with the corners, gently apply a plastic mediator. Click all the clips around the perimeter (usually 8-12 pieces). Do not force - if the lid does not respond, check if all screws are unscrewed.
- Turn off the curtain connectors: Find the curtain motor (usually located at the bottom or side). Carefully disconnect the power plume (don't pull the wires!).
Remove the mechanism.
- Unscrew the screws that fasten the guides (usually 2-4 pieces).
- Remove the curtain with the belt and motor.
If the curtain is stuck, check the guides for dust or deformation. Often the problem is a worn belt (it can be stretched or torn), in which case it is enough to replace only the belt, not the entire mechanism. Also check the gears of the motor - if they are chipped, you will need to replace the entire unit.

Installation of a new curtain: nuances and typical errors
Installation of the new curtain is carried out in reverse order, but there are several key points:
- Check the package: The box should have: the curtain itself, guides, belt, screws and engine (if you bought the full set). Compare the new curtain with the old one - they should be completely the same in size and mountings.
- Set the guides: Secure them with screws, but don't tighten them until the end - then you may need to adjust. Make sure they are parallel to each other (check with a ruler).
- Wear a belt: Make sure it doesn't twist and lies straight in the grooves. On the motor curtains, the belt should be pulled, but not pulled.
Get the motor on.
- Connect the connector to the motherboard (orientate by labeling: usually MOTOR or SHUTTER).
- Check the polarity β the wrong connection can burn the engine!
β οΈ Warning: If the curtain is jerking or squeaking, turn off the TV immediately, which is a sign that the belt is skewed or the guides are not parallel, and if you continue to operate in this mode, you will break the engine.

Before final assembly, lubricate the guide curtains with silicone lubrication (do not use WD-40 or oil-based oils!).This will extend the life of the mechanism by 20-30%.
Customization of the curtain after replacement: calibration and firmware
Some Xiaomi models (such as the Mi TV Q1 or P1) require calibration or resetting after the curtain is replaced, so that the TV can βrecognizeβ the new mechanism.
- Reset the curtain settings: Go to Settings β Device β Reset the curtain. Select Reset position and confirm.
- Manual calibration (if automatic didn't work): Open the curtain completely manually (pull the edge carefully). Press the Menu button on the remote for 5 seconds - the TV will remember the extreme positions.
Firmware update
- Check the version in Settings β About TV.
- If the version is outdated, update through Settings β System Update.
If the curtain does not work properly after replacing (for example, it does not close until the end or opens spontaneously), try:
- π Restart the TV (unplug the network for 1 minute).
- π§ Check the connection of the motor - perhaps the connector has moved away.
- π± Reset the remote settings (remove the batteries for 10 seconds).
In rare cases, you may need to run the engine through a service menu, and you need special tools (such as a USB-OTG cable and Mi Service Tool software), and if you are not sure about yourself, you should contact the service.

After changing the curtain, always calibrate! Without it, the TV can misidentify the extreme positions of the mechanism, which will lead to rapid wear and tear.
Frequent problems after replacement and how to solve them
Even if you do everything according to the instructions, there can be problems.
| Problem. | Possible cause | Decision |
|---|---|---|
| The curtain doesn't respond to the remote. | Unconnected motor connector or software failure | Check the connection, restart the TV |
| The curtain moves in jerks | Belt or guides skewed | Disassemble and align the mechanism |
| The curtain doesn't close until the end | Incorrect calibration | Reset your positions (see section above) |
| Extraneous noise at work | Dust ingestion or lack of lubrication | Clean the guides, grease with silicone |
| The TV will not be turned on after replacement | Short circuit or improper assembly | Check all the connectors, turn off the curtain and try turning on the TV |
If none of these things worked, it might be the motherboard (e.g., the engine controller burned), and it's a service that needs to be diagnosed, and it's also worth checking if a foreign object has gotten into the mechanism -- sometimes it's enough to remove the motif to make the curtain work as new.
