INTRODUCTION
Smart TVs are designed to switch seamlessly between multiple HDMI inputs, allowing users to connect set-top boxes, gaming consoles, streaming devices, and more. But in some cases, Mi TV users experience a frustrating issue—the TV gets stuck on a specific HDMI input and refuses to switch to others. This problem often occurs due to software errors, HDMI board issues, remote sensor faults, or internal motherboard malfunctions. Many customers ask whether the Mi TV Service Center can diagnose and repair this issue. The answer is yes. Mi-authorized centers are fully capable of handling HDMI-related faults through technical inspection, HDMI port testing, and software-level troubleshooting.

Why Mi TVs Get Stuck on a Specific HDMI Input
HDMI input issues may arise from both internal and external factors. Some of the most common causes include:
1. Faulty HDMI Cable or Connected Device
A damaged HDMI cable or malfunctioning external device can lock the TV onto one input. The system may not recognize other ports until the faulty connection is removed.
2. Corrupted Software Settings
A software glitch, outdated firmware, or internal system error may restrict input switching. Many Mi TVs require firmware updates to keep HDMI drivers functioning properly.
3. HDMI Board Failure
The HDMI switching IC or port circuit may get damaged, causing the TV to detect only one particular input.
4. Remote Sensor or Button Malfunction
If the remote sensor has issues, or the input button fails, the TV may not respond to input-switch commands.
5. Motherboard Issues
In some cases, overheating or component failure on the motherboard causes HDMI switching to malfunction.
Authorized Mi TV Service Centers inspect all these components carefully to ensure accurate diagnosis and repair.
How Mi TV Service Centers Repair HDMI Input Issues
When a TV is stuck on a particular HDMI input, technicians follow a structured diagnostic and repair approach:
1. Initial Hardware Inspection
The technician checks the HDMI cables, ports, and external devices connected to the TV. Faulty inputs or loose connections are corrected immediately.
2. Software and Firmware Diagnosis
Technicians check for outdated software, corrupted settings, or system errors. They may reinstall firmware or reset internal data to restore HDMI switching functionality.
3. HDMI Board Testing
Using specialized tools, service engineers test the HDMI chipset, switching ICs, and signal pathways. If the HDMI board is faulty, it can be repaired or replaced.
4. Motherboard-Level Troubleshooting
Heating issues, dry solder joints, and damaged capacitors on the motherboard may interfere with HDMI recognition. The service center performs chip-level repairs when required.
5. Remote and Keypad Testing
Input commands from the remote control and side buttons are checked to ensure proper response.
Mi-authorized centers or trusted partners like Dial Service Centre always use genuine spare parts when replacements are needed.
Is This Problem Repairable?
Yes. In most cases, the issue is completely repairable. Depending on the root cause, repairs may include:
HDMI port repair or replacement
HDMI switching IC replacement
Motherboard-level repair
Firmware reinstallation
Sensor or button repair
Cable or device-related corrections
Users should avoid attempting DIY fixes, as internal HDMI circuitry requires professional handling.

Other HDMI ports do not respond
The TV restarts when switching inputs
Screen shows “No Signal” even when the device is connected
