The screen-slip on Xiaomi devices is one of the most annoying malfunctions that can manifest as on smartphones (Redmi, POCO, Mi, and on TVs (Mi) TV, Redmi TV). The problem ranges from a barely noticeable twitch to a full-blown strobe effect that makes it impossible to use the gadget. 80 percent of the time, software failures are to blame, but sometimes the root of the evil lies in hardware breakdowns, from departed plumes to burnout of LEDs backlighting.
In this article, weโll look at all the possible causes of screen blinking with reference to specific models (for example, why you might want to see a screen blinking). POCO X3 Pro suffers more from flickering at low brightness, and Mi TV Q2 โ When you connect to consoles, and we give you step-by-step instructions with menu photos and video examples, and we'll focus on diagnostics: how to distinguish a software bug from a hardware breakdown without disassembling the device.
1. Programmatic reasons for screen blinking
Let's start with the most innocuous, firmware failures or application conflicts, which are the problems that most often show up after an update. MIUI or installing third-party programs:
- ๐ฑ Morgana starts through 5-10 minutes after
- ๐ The problem disappears in Safe Mode (Plug the shutdown button) โ "Safe regime")
- ๐ฎ The screen twitches only in certain apps (games, YouTube, camera)
- ๐ The flicker increases with low battery charge
The quickest way to check the software is to roll back updates or reset your screen settings, as Xiaomi smartphones do this:
- Go to Settings โ About the phone โ System update
- Click on three dots in the upper right corner โ "Update package"
- Select the previous version of the firmware (if available)
- Confirm the rollback
If the rollback doesnโt help, try resetting the screen settings:
Settings โ Display โ Additional settings โ Resetting screen settingsโ ๏ธ Attention: On Mi TVs TV Resetting the screen settings also resets the color calibration. After the procedure, you may need to reset the white balance through the Settings. โ Picture โ Additionally. โ Color mode.
2. conflicts with adaptive brightness and auto-regulation
Adaptive brightness function in MIUI And PatchWall (on TVs) often causes flickering, and the algorithm analyzes light through the sensor and adjusts the backlight, but sometimes it malfunctions -- especially on models with a lighting system. AMOLED-screens (Xiaomi 12 Pro, POCO F4 GT). Symptoms:
- ๐ The screen flashes when lighting changes (for example, when closing curtains)
- ๐ The flicker disappears if you manually fix the brightness
- ๐ B Settings โ Battery โ Battery use seen abnormal energy consumption by light sensor
Decision:
Turn off "Adaptive Brightness" in Settings โ Display.
Turn off "color auto-regulation" in Settings โ Display. โ Screen colors
Reset the light sensor settings through Settings โ All settings โ Resetting settings โ Resetting sensor settings
Reset the device-->
On Mi TVs. TV A similar problem may be related to the function AI Picture Engine. To turn it off:
Settings โ Picture โ Additional โ AI Picture Engine โ Turn off๐ก
If the adaptive brightness is too dim after the switch off, try manually adjusting the brightness curve in the engineering menu. To do this, type the phone code ##36446337## in the Phone app and select Display. โ Brightness Curve.
3. Problems with illumination (LED/AMOLED)
Xiaomi TVs of Q and A series (2020-2023 d.) most often the screen blinking is due to a malfunction LED-lighting โ especially if the problem occurs when turned on at full brightness or after 1-2 And on smartphones, it's a similar situation. AMOLED-displays where organic LEDs degrade over time.
How to diagnose:
| Sign. | Probable cause | Decision |
|---|---|---|
| Morganation at high brightness (>80%) | Overheating or wear LED-matrix | Limit brightness to 70%, check the TV ventilation |
| Dark spots. + flicker | Detachment of LED tapes (TV) or pixel burnout (smartphone) | Replacement of lights or screens |
| Morgania only on a gray background | Problems with the lighting driver | Reflashing or replacing the motherboard |
| The screen flashes when vibrating | A backlight plume gone | Disassembly and soldering of contacts |
To test the backlight on Xiaomi TVs, use the service menu:
Press sequentially on the remote:
Menu โ Settings โ All Settings โ General โ Device Preferences โ About โ Click 5 times on Android TV OS BuildIn the menu that opens, select Picture. โ Backlight Test. If the lighting blinks in the test, it's a hardware problem.
โ ๏ธ Note: On smartphones with AMOLED (Xiaomi 13 Ultra, Black Shark 5 Pro) low-brightness flickering (below) 20%) It can be normal behavior because of technology. PWM-To check if this is a defect, compare your deviceโs behavior to YouTube test videos (search on request "model_name PWM test").
4. Failures of plumes and contacts
Physical injuries are the second most common cause of blinking, and Xiaomi smartphones are the most commonly affected:
- ๐ฑ Display plume (especially after drops or screen replacement)
- ๐ Battery contacts (lead to voltage drawdowns)
- ๐ ๏ธ Charging connector (if the blinking coincides with the cable connection)
On Mi TVs. TV vulnerable:
- ๐บ LVDS-cable (connects the motherboard to the matrix)
- ๐ Connectors LED-lights (oxidized over time)
- ๐ ๏ธ Contacts of the power supply (lead to unstable voltage)
Diagnosis:
- Check whether the blinking increases when pressing on the body (for example, at the back of the TV or on the edges of the smartphone).
- Connect the device to charging โ if the blinking syncs with charging, the problem is in battery or power supply contacts.
- Try to move the plume easily (at your own risk!) - if the picture changes, soldering is required.
How to check the plume on a smartphone without disassembly?
For Xiaomi TVs, there is a special test for the integrity of plumes:
In the service menu (see section 3), select:
Service โ Factory Test โ Cable Test5. Conflicts with external devices
If the screen starts blinking only when connected to the console (Xbox, PlayStation), receiver or computer โ the problem lies in the incompatibility of protocols. HDMI Or DisplayPort. Typical scripts:
- ๐ฎ Morganation at 120 Hz frequency per Mi TV Q1E (problem HDMI 2.1)
- ๐ฅ๏ธ The screen twitches at resolution 4K PC (lack of cable bandwidth)
- ๐ก Flickering when connected through AV-receiver (conflict) EDID)
Decisions:
Try another cable (preferably certified) HDMI 2.1 for 4K/120Hz)
Turn on Game Mode on your TV (Settings) โ Picture โ Picture modes)
Turn it off. HDR externally
Update the firmware of the TV and consoles
Reset the settings. HDMI-Port settings (Port settings) โ Devices โ Reset HDMI)-->
For Mi. TV Stick and other Xiaomi consoles have a separate instruction:
Configures โ Display and Sound โ Screen resolution โ Choose 1080p instead of 4K
Settings โ Additional โ HDMI Mode โ Select โPCMโ instead of โAutoโโ ๏ธ Note: On Xiaomi TVs with MediaTek processor (e.g. Mi) TV P1) There may be a conflict with consoles on Realtek chips, in which case only firmware of the TV on the custom version (for example, ATVXperience) will help).
6.Overheating and nutritional problems
The screen freeze when heated is a classic symptom of trottling (automatic performance decline), as is seen on Xiaomi smartphones:
- ๐ฅ After 15-20 play-off
- ๐ Along with the drawdowns FPS benchmark
- ๐ Charging from non-original adapters
On TVs, overheating is more often caused by:
- ๐บ Dust-filled vents
- ๐ Unstable network tension (especially in rural areas)
- ๐ ๏ธ Failure of capacitors on the power supply unit
Diagnostics and solutions:
| The device | Reason. | How to check | Decision |
|---|---|---|---|
| Smartphone | Processor overheating | Install. CPU Monitor from Play Market | Limit productivity in Settings โ Battery โ Performance mode |
| Smartphone | Unoriginal adapter | Check the voltage through Ampere | Use only the original Xiaomi RAM (20W/33W/67W) |
| Television | Dustiness | Light a flashlight into the ventilation holes | Blow the dust with compressed air (not disassembling!) |
| Television | Power drawdowns | Connect through UPS stabilizer | Use a network filter with anti-racing protection |
For smartphones with Snapdragon 8 Gen 1/2 (Xiaomi 12 Pro, POCO F4 GT) There is a hidden setting of limiting heating:
Enter the phone code in the appendix:
##4636## โ โBattery Informationโ โ โCPU Temperature Limitโ โ Select โBalancedโ๐ก
If the Xiaomi TV blinks only when turned on (the first ones are the ones that are not on) 5-10 This may be a sign of a fault in the filter capacitors in the power supply, in which case the capacitors need to be replaced with analogues with a higher capacity (for example, instead of using the capacitors). 1000ฮผf ร 16Put in 1500ฮผf ร 16V).
7. Matrix defects and manufacturer's marriage
If the screen blinks immediately after purchase or the problem appears for no apparent reason (without falls, updates, connecting new devices), a manufacturing defect is possible.
- ๐ฑ Xiaomi 13 Lite (problems with the AMOLED-Samsung matrices E4)
- ๐บ Mi TV Q2 75" (backlighting defects in the first batches of 2022)
- ๐ฑ POCO X5 Pro (flickering at 120 Hz refresh rate)
How to proceed:
- Check the serial number of the device on the Xiaomi website (https://www.mi.com/global/verify) โ If the gadget is warranty, contact the service.
- Shoot a video demonstrating the problem and send it to Xiaomi support via Settings โ The phone. โ Revocation.
- For TVs, check the production date (the first 6 digits of the serial number). If the device is released before 2022.06, there is a high probability of backlight failure.
In some cases, marriage can be eliminated in a programmatic manner. POCO X5 Pro blink at 120 Hz is corrected by shutting down the function MEMC (thruster):
