We'll look at all the ways we can turn on, from standard remote launches to alternative methods using physical buttons on the case, and we'll look at the common bugs that might make the Mi TV A2 turn off, and we'll give you a checklist to diagnose the problems. If you just purchased the device or experienced problems after the upgrade, here you'll find the answers.
Where is the power button on Xiaomi Mi TV A2
Unlike many other brands, the Xiaomi Mi TV A2 has a physical power button hidden and not always obvious. Its location depends on the diagonal of the model and the year of release, but in most cases it is on the right sidebar or the bottom frame under the brand logo, you need to look for a small cutout or protrusion that can be pressed with a finger or a thin object.
On some modifications (e.g. Mi TV A2 43" and 55"), the button is combined with JOYSTICK, a mini joystick for navigating menus without a remote, in which case a short press turns the TV on/off, and a long (3-5 seconds) can start recovery mode.
- 📍 43" and 50" - button on the right side edge, closer to the back cover.
- 📍 55" and 65" - button under the Mi logo on the bottom frame (sometimes you need to press with force).
- 📍 75" - button-joystick on the back, to the right of the connectors HDMI.
If you can't find the button visually, try swiping your finger along the right and bottom edges of the case - it usually feels like a small indentation. On models with a metal body, the button can be almost flush with the surface, so light the panel with a flashlight for better visibility.
Standard Enablement with a DU Remote
The most obvious way is to use the original remote control that comes with it. But even here, there are nuances. First, make sure that the remote has working batteries (often new batteries are discharged or installed incorrectly), and second, check if the infrared lens is locked on the remote or TV - even a small obstacle can block the signal.
Instructions for inclusion:
- Point the remote to the IR receiver of the TV (usually located at the bottom in the center or on the right).
- Press and hold the power button (🔄) during 1-2 Seconds before the TV lights up.
- If the TV doesn’t react, try to bring the remote closer (at a distance of 1-2 meters) or replace the batteries.
On Xiaomi remotes, the power button is often paired with the Mi button (brand logo), in which case one short press turns the TV on/off, and a long (3 seconds) can activate the voice assistant. If the remote doesn't work at all, try resetting it by holding the Menu + OK buttons for 10 seconds.
Install new batteries (AAA)
Check the polarity of the (+/-) batteries
Make sure the IR lens is clean.
Direct the remote directly to the TV receiver

Alternative ways to include without remote control

- Download the app from the official store (Google Play or App Store).
- Connect your phone and TV to the same Wi-Fi network.
- In the app, select the Mi TV A2 device and follow the instructions on the screen.

- 🔌 Connect the device to the port HDMI ARC (usually marked).
- 🎮 Turn on the external device – the TV should turn on with it.
- ⚙️ In the settings of the external device, activate the option HDMI-CEC (It could be called Anynet.+, Bravia Sync or Simplink).

Frequent User Mistakes and How to Avoid Them
Many of the problems with the Xiaomi Mi TV A2 are due to user misconduct, and here are the most common mistakes:
- 🔌 Using a non-original power supply. Xiaomi TVs are sensitive to voltage. Power supply from other equipment can disable the motherboard.
- 🔄 Interrupting firmware updates: If the TV is updated, it cannot be turned off or disconnected from the network, this can lead to "bricking" (complete inoperability).
- 📶 Connect to an unstable Wi-Fi network. If the signal is weak, the TV can freeze during the activation stage. Use the cable connection (Ethernet) for the first setup.
- 🔋 Ignoring the battery discharge in the remote, even if the monitor on the remote is on, the batteries can be discharged so that the signal does not reach the TV.
Another common mistake is to try to turn on the TV immediately after transport in the cold season. If you bring the Mi TV A2 from the street in the winter, let it warm up to room temperature (2-3 hours), condensation inside the case can cause a short circuit.
⚠️ Warning: If the TV was turned on during a thunderstorm and then stopped responding to buttons, do not try to repair it yourself.
