The strong outbreak of Internet TV has been going on for nearly two years. It has changed the traditional television industry that has lasted for decades. Since its inception, Internet TV has brought a high cost-effective label. In order to accumulate user groups, it is not hesitate to use concessions or even non-profit making methods to attract more users. Behind the suffocating of many manufacturers, it also makes the entire TV industry unhealthy. The direction of development.

Dismantle PPTV N55 TV
However, starting in 2017, Internet TV has finally ushered in a year of transition under the twin trends of panel prices and consumer upgrades. From the consumer's point of view, although Internet TV can bring rich content and relatively low prices, TV is not a consumable product after all. At present, users tend to have better quality when they purchase. The high-end trend of TV is also being accepted by the market step by step. This has also become the direction of development of the TV industry this year. What does the flagship Internet TV rely on?
As a result, we will see that Internet TV products are escaping from the low-end market, and the fireworks of price warfare has also faded. We have placed our efforts on high-end products. Although many Internet companies have launched flagship TV products this year, they still have a significant advantage in terms of price. This has also caused consumers to question the quality of such products. PPTV N55 teardown video
For a television work material is elegant, through the dismantling to verify is the most appropriate. Today, the model we want to dismantle is PPTV's new flagship model, PPTV N55, launched at CES Asia in June. This 55-inch new generation of light luxury products priced at 5,999 yuan, PPTV push this year's models, but also for the transformation. What kind of high-end models in the Internet TV industry can be reached? Let us reveal through dismantling.

The back design does not leave regret
Overall, the PPTV N55 TV has undergone a full-scale upgrade in appearance design. It not only uses clever color schemes, but also does not confuse work materials. It also handles details very well. Although the homogenization of TV is becoming more and more serious, and even after covering with the Logo, it does not even make any difference. However, the overall appearance of the PPTV N55 TV reflects a distinctive design style, and it is rather a kind of elegant gas field.
· PPTV N55 TV rear shell and motherboard dismantling
The dismantling of the PPTV N55 TV is almost impossible. Unscrew the 12 screws on the back cover to uncover it. During the dismantling process, it is recommended that the TV be flipped over onto a sponge or a carpet. Because the LCD screen is easily scratched, protective measures must be taken.
The label tears invalid warranty
In our actual dismantling process, we didn't know that there was a screw hidden under the label, so we couldn't open the back cover. After some research, we discovered this mystery... but it should be noted that If the label is torn off, the manufacturer will not guarantee it. Therefore, it is not recommended that you dismantle the television in your home.
Unplug five keys to remove the back shell
Another point to note is that, after opening the back cover, you need to unplug the connection line between the back cover and the five keys, you can not pull the hard disk, destroy the five key modules.
Internal main components
After opening the back cover, the internal structure is clearly visible and is divided into six major parts. These are the power board, T-CON (board driver) board, TV board, Bluetooth board, IR (remote control receiver) board, and WIFI board. In addition, there are JBL speakers distributed on both sides of the bottom. Overall, the layout is relatively neat, avoiding the cross-knots of the lines, and it is also fixed with tape.
Motherboard connector
Removing the motherboard requires a total of six cable removals. In addition to the five on the diagram, there is an IR board cable at the bottom of the motherboard. It is important to note that when unplugging these cables it is also not possible to pull the cables. When unplugging the FFC screen cables, the upper buckle must be opened. The remaining cables must be pulled out of the upper convex part.
PPTV N55 TV Motherboard
In order to achieve a better heat dissipation effect for the chip and memory, the heat sink covers most of the area of ​​the motherboard. Unfortunately, since the heat sink is soldered on the motherboard, we cannot see the TV's chip and memory. PPTV N55 official hardware configuration is equipped with the Mst**A938 currently the strongest TV chip, 4GB (DDR3 + DDR4) memory + 32GB eMMC 5.1 large-capacity flash memory, configuration is very impressive, in the read and write speed, graphics operations and space completely no need to worry.
summary:
From the dismantling of the motherboard of the PPTV N55 TV, the materials used for the work are more conscientious, and the details of the design also protect the motherboard itself. In the external interface and welding process is also very good, not the poor quality of the material. At the same time, whether it is a TV chip or memory, flash memory and other configurations have reached the current flagship TV standard, from the point of view of the configuration, the hardware process is absolutely worthy of such a price.
· PPTV N55 TV power board and T-CON board dismantling
The disassembly of the power strip of the PPTV N55 is also very simple. Before unscrewing the five fixing screws, unplug the power strip from the main board, the backlight power supply cable and the power switch cable. It should be noted that each socket is equipped with a snap, one is to ensure tight type, and the other is to protect the interface circuit, so it must be careful enough in the process of disassembly.

When disassembling, pay attention to the buckle of the cable plug
PPTV N55 power board
The PPTV N55 power board adopts a black PCB board, covering a relatively objective area, and the material used is also very solid. Multiple thermistors and electrolytic capacitors are provided in different module areas to provide a more stable and safe circuit for the entire power board. At the same time, transformers provide a stable source of energy for televisions.
T-CON board connection cable
The T-CON board, also known as the liquid crystal driver board, is also one of the core modules. Its role is to process and control the signals sent from the core processor, and then send it to the LCD panel and finally present the image. The more important integrated circuits on the driver board are the master chip and the microcontroller.
First open and then insert and remove the fixed buckle
The input interface of the driver board is connected to the main control new board of the TV motherboard through the connection cable, and the output interface is connected to the liquid crystal panel through two signal transmission cables. The three connection cables must also pay attention to the buckle at the interface during the plugging and unplugging. , Remove the cable after opening the buckle.
PPTV N55 LCD Driver Board
The driving board of PPTV N55 TV uses the original master chip of LG. The chip is clearly marked with the words LG Display. The model of this chip is TLi2380EP. It is also the chip that most domestic TVs use, and they are more mainstream.
summary:
From a whole point of view, the power supply board of PPTV N55 TV provides stable stability to the entire circuit while providing stable current, and selects the more reliable LG Display master control on the LCD driver board. The chip ensures the image processing capability of the TV and the entire hardware configuration meets the mainstream level.

Bluetooth module
On the Bluetooth module, built-in Bluetooth 4.1, and supports backward compatibility, can be combined with other Bluetooth + wireless network module combinations, and other radio frequency operation, wireless connectivity is very strong.
JBL sound module
PPTV N55 has a slim body of 9.9mm, and it is not an easy thing to be able to balance the sound quality even in the thin form. From the internal structure point of view, PPTV N55 to allow enough space for the audio part, while this set of JBL enthusiast speakers also support Dolby Dolby sound. From the above figure, we can also see that the side of the speaker has also been shock-absorbing treatment, not missed a trace of detail.
PPTV N55 uses LG original IPS hard screen
On the screen, PPTV N55 TV uses LG original IPS 4K screen, physical resolution can reach 3840*2160, static contrast can reach 1200:1, brightness 280cd/m2, dynamic response 8ms. These parameters are official data, and from our actual test results, it is better than this standard.
Dismantling summary:
The dismantling of the PPTV N55 TV was the first attempt of Zhongguancun Online in the past two years. The entire dismantling process can be said to have been carried out very smoothly. This is inextricably linked to the rational design and layout of television. From the perspective of internal structure and hardware configuration, PPTV N55 is by no means a stack of cottage products. All parts and core components are from mainstream manufacturers, and the control of details is satisfactory.
PPTV N55 TV dismantling
Although once the Internet TV market was a mixed bag, in order to keep down prices, it did not hesitate to use costly materials to reduce costs, which also cast a shadow on the quality of Internet TV. However, under the general trend of consumption upgrade this year, Internet TV habitually competing for low-end markets has begun to transition to high-end. In fact, before the dismantling, the author also pinched his sweat for the quality of Internet TV. However, from the actual dismantling situation, it is still relatively satisfying. There is absolutely strength to compete with traditional brands. The entire TV industry can only get better and better in this environment of good competition, blindly using low-end low-quality products to fight prices, fight marketing, and ultimately victims or consumers.
