A very widespread occurrence in Mi TV 4A and 4X series where individual LED diode beads burn out, cutting off the backlight circuit. We replace the full aluminum array for crisp, even illumination.
If your television gets stuck on the orange MI logo or restarts endlessly, the PatchWall eMMC flash memory has encountered corrupted partitions. We reprogram firmware using dedicated chip programmers.
Most Mi TVs use single 3-in-1 combo boards integrating power, logic, and backlight inverter. We diagnose failed MOSFETs, diodes, and PWM controller chips at the board level to save customer cost.
If your voice remote loses pairing frequently, we replace the internal Bluetooth/Wi-Fi combo daughterboard or update the Bluetooth stack software.
Display shaking or colored horizontal bands are fixed through source COF IC bypass and clock signal filtering without requiring full display panel replacement.
Vibrating, crackling sound or total silence from the built-in stereo speakers is resolved by installing original Mi replacement speaker chambers with acoustic damping.
