You've turned on Xiaomi Mi. TV, Redmi Note or other device brand, but instead of normal boot only see a flashing indicator and black screen? This problem is found in smartphones and smart equipment Xiaomi β from TVs to routers. In 80% of cases, it can be eliminated on its own, but first you need to understand what exactly is the failure: with firmware, power supply, battery or hardware breakdown.
In this article, weβll look at all the possible reasons Xiaomi is blinking but not turning on, from the banal battery discharge to critical bootloader errors. Youβll learn how to diagnose a problem by the nature of the blinking (e.g., red/white/blue LED, blinking frequency), what manipulations can be done at home and when itβs time to bring the equipment to the service. For convenience, weβve compiled step-by-step instructions with recovery menu photos and video examples, and added an error code decoding table for different models.
1. Decoding of the indicator blinking: what color and frequency mean
The first thing to do is to analyze the blinking pattern, and Xiaomi devices (especially TVs and smartphones) have LED indicators that encode different types of errors.
- π΄ Red flashing lights - power problems (power supply, battery, motherboard). TV could be a mistake 3-5-1 (faultyness).
- π΅ Blue flashing lights are firmware or bootloader failures (often after a failed update). Redmi/POCO It may indicate bootloop.
- βͺ White flashing light β the device tries to boot but encounters an error (e.g. damaged partition) /system).
- π’ Green flashing lights are rare, but can signal problems with RAM (RAM).
Also pay attention to the intervals of blinking:
- π 1 long + 3 short ones - mistake EDID (on television, connected with HDMI-port).
- β‘ Fast chaotic blinking β short circuit or overheating of the chip.
- β³ Constant blinking with pauses of 2 seconds - waiting for the command from the remote (on Mi) TV Stick).
If the indicator flashes without pause and the device does not respond to the buttons, this is a sign of hardware failure (90% probability of a malfunction of the motherboard or power supply), in this case, self-repair is dangerous: multimeter diagnostics and soldering of components are required.
2. Software causes: from firmware failure to bootloop
In 60 percent of cases, flashing is caused by software errors that can be fixed without disassembling the device.
Failed firmware update
If Xiaomi started flashing after the update on the air (OTA), There was probably a failure when writing files to the section. /system. It's typical for:
- π± Redmi Note smartphones 8/9/10 prior MIUI 13/14.
- πΊ Mi TVs TV 4S/5X when switching to Android TV 11.
π§ Solution: forced reset to factory settings or flashing through Fastboot/Recovery. Detailed instructions - in the section 4.
Bootloop (cyclical reboot)
Bootloop is when a Xiaomi device is constantly restarting without reaching the boot of the system.
- π The Mi or Redmi logo appears and disappears in a cycle.
- π΅ The blue indicator flashes with intervals ~1 second.
- β οΈ The device heats up (especially the memory chip).
Causes of bootloop:
- π οΈ Incorrect editing of the build.prop file (for example, when rooting).
- π Interrupted firmware update (cable pulled or battery sat down).
- π§© Core conflict with Magisk or Xposed modules.
What to do if bootloop after rooting?
Damage to the data section
If the indicator flashes white and the device does not load beyond the logo, a file system error may occur (e.g., a file system error, ext4 or f2fs). It happens when:
- π Abrupt power outage during data recording.
- π Installation of custom firmware with errors.
- π¦ Viral infection (rarely, but occurs on the POCO F1/F3).
π§ Solution: check and restore the section through ADB or TWRP. Diagnostic teams:
adb shell e2fsck -f /dev/block/bootdevice/by-name/userdata
adb shell resize2fs /dev/block/bootdevice/by-name/userdata3. Hardware causes: from battery to motherboard
If the software methods didn't work, the problem is the hardware.
| Reason. | Signs. | Models at risk | Cost of repair (β½) |
|---|---|---|---|
| Battery discharge/blowning | Red light flashes 2 times, the device does not respond to charging | Redmi 7/8/9, POCO X3 | 1 200β2 500 |
| Failed power supply unit (on TV) | Flashes red with pauses of 3 seconds, no image | Mi TV 4A/4S (until 2020) | 1 800β3 500 |
| South Bridge Heap (Memory Chip) | Chaotic blinking, device warms up, does not turn on | Redmi Note 5/6, Mi 8/9 | 4 000β8 000 |
| Problems with illumination (on TV) | The indicator is green, but the screen is black (in the light of the flashlight you can see the image) | Mi TV 5X/6 | 2 500β5 000 |
| Short circuit on the motherboard | The device shuts down after 2-3 seconds after the power connection | Any model over 3 years old | From 5,000. |
β οΈ Attention: If after a fall or impact Xiaomi began to blink and not turn on, do not try to charge it - this can aggravate the short circuit.
3.1 How to check the power supply (for Mi) TV)
If Mi flashes TV, First, check the power supply:
- π Turn off the TV for 1 minute, then turn it on again.
- π Check the power supply for bloated capacitors (if you have experience).
- π Measure the voltage at the output of the BP multimeter (should be) 12V/19V model-wise).
π‘ Tip: If you have Mi TV 4S 55" or similar, try plugging in another power supply with the same voltage. Often the problem is solved by replacing the PD in 1,500 to 2,000 times. β½.
Diagnostics of the battery (for smartphones)
On Xiaomi smartphones, flashing a red indicator is often associated with the battery.
Connect charging β if the indicator doesnβt light up, the problem is in the power controller
