The biggest feature of Xiaomi TV 3 is the split design, namely Xiaomi TV host = audio + smart TV motherboard + millet box, the host connects to the screen through a "rice line", and the "rice line" is synthesized by the power line and the signal line.
Other product keywords include all-metal body, 11.6mm ultra-thin, original LG hard screen, wide color gamut, independent speakers, MEMC motion compensation, 1.4GHz frequency Mstar 6A928 processor quad-core processor, etc. (detailed configuration ). Lei Jun, chairman of Xiaomi, said that this is a product that penetrates the bottom line of psychological prices.
After the real machine map tour, this time the split design, panel, chip information, etc. are presented in front of you. Disassembly experts believe that Xiaomi TV 3 is unbelievably concise after opening the backboard. If you compare the internal dismantling of a brand 4K TV, it can be said that the work of Xiaomi TV 3 is really the conscience of the industry.
Then the value of 4,999 yuan is not worth it. Let's take a look at it -
Our disassembly tools include multi-function screwdrivers, electric screwdrivers, rockers and magnifiers.
After putting the TV on the workbench, the next step is to disassemble. There are 22 screws on the back of the millet TV. You can solve the problem with a screwdriver.
Continue to tighten the screw ing. . . The electric screwdriver is fast.
After the screws are removed, the integrally formed plastic back shell is easily opened, and the internal structure of the Xiaomi TV 3 is about to be revealed.
After uncovering the backboard, this is the case. The simplicity is unbelievable. After comparing the internal disassembly of a brand 4K TV, it can be said that the work of Xiaomi TV 3 is really the conscience of the industry.
We will take a closer look at the circuit board of the TV. It is designed with black slabs, and various components are arranged in a distributed manner. The workmanship is relatively good.
A detailed view of the power section of the TV screen.
This part is the board for image processing and signal output, and dynamic image compensation and area backlight control are also handled in this part.
Next is the panel problem we are concerned about. It can be seen that the 60-inch IPS wide viewing angle panel from LG Display is used. The model of the panel is MI60TV (T8) for Xiaomi, and the package of the LCD module is Completed in Ruiyi.
Next is the control chip part of the LCD module, when a small screwdriver comes in handy.
It can be seen that the control chip of the liquid crystal is the original chip of LGD.
Let's take a look at the details of the LCD module. You can see that the side-in LED backlight is located in the lower frame of the camera. At this point, the disassembly of the screen section has come to an end.
The next step is to disassemble the main unit and the audio part. First, take a look at the front.
The main unit and audio are made of all-metal and the screw holes are underneath.
The process of removing the screws is the same as that of the screen, but I will go into details.
After the screws are removed, they cannot be opened immediately, because there is a snap-fit ​​structure inside, and we need to use the warp pieces we prepared.
Slowly open the cover on the main unit.
This is the complete structure after removing the upper cover. You can see that the sound is separated on both sides, and the middle part is the motherboard chip.
Let's take a look at the control chip of the button on the top cover.
To see the motherboard part, still use a small screwdriver to disassemble a few screws.
This is the complete motherboard part.
We look at the details with a magnifying glass. First, the largest chip is the built-in MStar 6A928 TV processor, next to the built-in Samsung memory chip.
Let's look at the details on the motherboard.
The dismantling is still going on, and now it is the part that removes the sound.
Then we can take out the motherboard chip, the various interfaces and chips are highly integrated, and the layout is quite reasonable.
You can see the built-in four 2.5-inch mid-woofers and two 20-core dome tweeters. At the same time embedded Dolby Audio technology, support for virtual surround, bass enhancement, dialogue enhancement, automatic volume balance.
This is all the accessories after the host is disassembled.
Here, the dismantling part will come to an end, we can understand that this Xiaomi TV 3 is very clean and tidy inside, using the IPS hard screen made by LGD, the split internal circuit layout is more reasonable, the details work fine, this is also It is worthy of recognition.
