Xiaomi TVs 2015015: What model is it and how to identify it?

If you’ve encountered the Xiaomi 2015015 label on a box, in documents, or in the settings of a TV, you’re looking at one of the company’s early Mi TVs, which is not the name of the series, but the internal accounting article used in 2015-2016, most often hiding behind Mi TVs in the Mi TV 2 or Mi TV 3 line, released for the Chinese and global markets.

The problem is that Xiaomi didn’t stick to a single numbering system: the same article could refer to different modifications depending on the region of sale. For example, 2015015 could denote Mi TV 2 40 for China and Mi TV 3 43 for Europe. In this article, we will discuss how to accurately determine the model of your device, what specifications these TVs have, and what to look for when buying or repairing.

What does the 2015015 code mean in the Xiaomi nomenclature?

The 2015015 code is an internal batch ID that Xiaomi assigned to the TVs during the production phase, and it doesn't reflect the series or diagonal directly, but it narrows the search.

• 📅 2015 is the year of release (or planned release). In the case of the Mi TV, this usually means models released in late 2014 – early 2016.
• 🔢 015 is the serial number of the batch or modification, for example, 001 could indicate the base version, and 015 could indicate the updated revision with corrected bugs.

It is important to understand that Xiaomi often changed articles for even one model depending on the configuration (for example, with a Bluetooth or IR remote), region (China/EU), or firmware version. So the same code 2015015 could refer to TVs with different arrays, processors or even diagonals.

To avoid confusion, the manufacturer later switched to more straightforward labeling (e.g. Mi TV 4A 32), but the early batches were left with numerical codes. If you buy a used TV with this label, be sure to check it by the serial number or settings menu.

What Xiaomi models have the 2015015 code?

Based on the analysis of documentation and user feedback, the 2015015 code is most commonly found in the following models:

Note that even if your TV makes this list, the hardware stuffing may have varied depending on the production date. For example, early Mi TV 2 40s had problems overheating due to a weak cooling system that was fixed in revisions 2015020 and higher.

If you are not sure about the model, check it through the TV menu:

1. Open the Settings. → On TV.
2. Find the Model or Model Number strings (e.g. L49M2-3A).
3. Compare the table above or search for this code in the Xiaomi database.

💡

If the settings don’t include model information, look at the sticker on the back of the TV – it usually shows the full article, such as the MDZ-49-AA for Mi TV 2 49.

How to distinguish Mi TV 2 from Mi TV 3 by 2015015?

The main difference between these series is the hardware platform and the software, and here are the key features:

• 🔧 Mi TV 2: MStar 6A928 or 6A938 processors (in 4K- models). Android 4.4 or modified MIUI TV based on Android 5.0 Support 3D only in suffixed -3D models. IR remote (infrarred) without Bluetooth.
• 🔧 Mi TV 3: Amlogic T962 or MStar 6A938 processors (depending on the revision). Android 5.0/5.1 with PatchWall shell (global versions); Support HDR in 4K- resolution models; Bluetooth remote control and voice control (in some regions).

If your TV has the code 2015015, but the menu indicates Android 5.0 and the Amlogic processor - you are most likely Mi TV 3. If the Android version 4.4 and the MStar processor is Mi TV ZXPH0006QXZ.

Another way to distinguish them is by the connectors:

• 🔌 Mi TV 2: 2×HDMI, 1×USB 2.0, composite input, optical output (not in all versions).
• 🔌 Mi TV 3: 3×HDMI (one with ARC support), 2×USB (one 3.0), no composite input.

Technical characteristics of TVs with code 2015015

The following are the average characteristics for models that may have had this article: the specific parameters depend on the audit and the region:

Important: TVs with code 2015015 do not support modern video formats (for example, Dolby Vision or AV1). The maximum they are capable of is playing H.264/H.265 in Full HD. If you need support for 4K or high bitrates, these models will not work.

Also, you should consider that Mi TV 2 has often had a problem with overheating due to a weak cooling system. If the TV is running at high brightness for a long time, the protection may go off and the screen will go out. Mi TV 3 partially solved this problem, but it is still relevant for early installments.

💡

TVs coded 2015015 do not receive official Android updates after 2018, which means no support for new apps (like Netflix or Disney+) and security vulnerabilities.

How to check the exact model by serial number?

If only the 2015015 code is listed on the box or in the documents, the most reliable way to identify the model is by the serial number.

• 📄 On a sticker on the back of the TV.
• 📺 In menu: Settings → About TV → Status.
• 📦 On the box (if the original packaging is retained).

The serial number Xiaomi has a format like MDZ-XX-XX-XXXXXXX or AC15XXXXXXXX. The first characters often indicate the model:

• MDZ-40-AA → Mi TV 2 40".
• MDZ-49-AA → Mi TV 2 49".
• L43M3 → Mi TV 3 43".

If the serial number starts with AC15, it indicates 2015, but it doesn't give you model information.

Problems and typical malfunctions of models with the code 2015015

Mi TV 2/3 with this article have a number of typical problems related to age and design features:

⚠️ Warning: If your TV suddenly turns off after 10 to 30 minutes of operation, it's a sign of overheating. Don't ignore the problem - prolonged use in this mode can cause the motherboard to fail.

• 🔥 Overheating: Symptoms: spontaneous shutdown, screen flickering, artifacts in the image. Cause: weak radiator on the processor or dry thermopaste. Solution: disassemble and replace the thermopaste, install additional cooling.
• 🔊 Sound problems: Symptoms: no sound through HDMI, cracking in the speakers. Cause: malfunction of the audio amplifier or capacitors on the board. Solution: replace the capacitors or the entire audio board.
• 📶 Wi-Fi problems: Symptoms: persistent connection breaks, slow speed. Cause: an outdated Wi-Fi module (usually Realtek RTL8188 or Broadcom BCM4335) Solution: Ethernet connection or module replacement (requires rations).

Another common problem is power failure: the TV doesn't turn on, the indicator flashes red or doesn't respond to the remote, and 80% of cases are caused by bloated capacitors that can be replaced by yourself (if you have experience with a soldering iron).

To diagnose malfunctions, we recommend using the service menu.

1. Turn off the TV.
2. On the remote, press sequentially: Menu → Up → Up → Down → Down → Left → Left → Right → Right.
3. Turn on the TV – the service menu with equipment tests should open.

⚠️ Warning: Do not change the settings in the service menu unless you are sure of their value! Incorrect settings can lead to a breakdown of the matrix or power supply.
