The strong outbreak of Internet TV has continued for nearly two years, and its appearance has changed the traditional TV industry that lasts for decades. The Internet TV has a high cost-effective label from the date of birth. In order to accumulate user groups, they have attracted more users without having to make money. Behind many manufacturers kill, but also let the entire TV industry is unhealthy. The direction of development.
However, from 2017, Internet TV has finally ushered in the year of the transformation in 2017, the double trend of the panel price increase and consumption upgrade. Standing at the perspective of consumers, although Internet TV can bring rich content and relatively low prices, TV is not easy consumables after all, and the user is more preferred when purchasing. The high-end trend of the TV is also accepted by the market in a step, which has become the direction of the development of TV industry this year.
Flagship Internet TV is not reliable?
As a result, we will see that Internet TV products are leaving low-end markets, and the fireworks in the price war have also fallen, and the power points are placed on the middle and high-end products. Although many Internet manufacturers have launched flagship-level TV products this year, they still have a small advantage in prices, which also makes consumers have questioned the quality of such products.
For a TV work material, verification is performed by dismantling. Today, the model we have to dismantle is the new flagship model -PPTV N55, which PPTV is launched in June CES ASIA. This 55-inch new generation of light luxury products is priced at 5,999 yuan, which is PPTV's push machine model this year, and it is also a transformation. What is the high-end models of the Internet TV industry to achieve the height, let us be unveiled by dismantling.
PPTV N55 TV has now received one of the Idea Awards in one of the world's three major design awards, highlighting the strength, and the design style has a big change in the past. Due to the following detailed evaluation articles, the side focus of this article is not the appearance, so we only make a brief evaluation of the work materials of this TV.

Use the double-sided seamless bending process without the cost
Back design does not regret
Decomposition of PPTV N55 TV has little difficulty, and it can be unveiled with 12 screws of the back cover. In the dismantling process, it is recommended to put the TV on the sponge or carpet, so it is necessary to protect measures due to the very easy to scratch of the liquid crystal screen.
Label tearing quality insurance
In our actual dismantling process, I don't know if a screw is hidden under the label, so I will not open the back cover. Later, after a study, I found this mystery ... but I have to pay attention to it. Once this label is torn, the manufacturer will not be warranty, so it is not recommended to dismantle the TV in the home.
In still, it is necessary to note that after opening the rear cover, you need to unplug the cable between the back cover and the five-key, and can not pull the hard to draw, destroy the five key modules.
Internal main components
After opening the rear cover, the internal structure is at a glance, mainly divided into six parts, the power board, T-CON (LCD screen drive) board, TV motherboard, Bluetooth, IR (remote reception) board, WiFi board, remove these In addition, there is a JBL speaker part distributed on both sides of the bottom. Overall look at the layout of the layout, avoiding the cross-knisting of the line while also fixing with the tape.
Removing the motherboard, a total of six connecting lines, remove the top five, and an IR board cable is at the bottom of the motherboard. It must be noted that when unpluging these connecting lines, it is also not to pull the hardness. When the FFC screen cable is unplugged, open the buckle above it, and the remaining cable should be pulled down.
In order to achieve a better heat dissipation effect, the heat dissipation plate covers the majority of the motherboard, and unfortunately, because the heat dissipation plate is soldered on the motherboard, we can't see the chip and memory of the TV. The official hardware configuration of PPTV N55 is equipped with MSTAR6A938's most powerful TV chip, 4GB (DDR3 + DDR4) memory + 32GB EMMC 5.1 large-capacity flash memory, configuration is very considerable, not worry about reading and writing speed, graphical operation, and space.
From the motherboard dismantling of PPTV N55 TV, the workmanship is more conscience, and it is also very good to protect the motherboard itself in the design of the details. It is also very good in external interfaces and welding processes, not a cottage inferior material. At the same time, whether it is a TV chip or memory, flash memory, all the standards of the current flagship TV model, from the configuration, hardware process, absolutely worthy of this price.
PPTV N55 TV power board and T-CON board disassembly
PPTV N55 power board dismantling is also very simple, before unlining five fixed screws, first unplug the power board and motherboard connecting line, backlight supply cable, and power switch cable. It should be noted that each junction is equipped with a buckle, one is to ensure the tight type, and the other is to protect the interface circuit, so it must be carefully enough during the disassembly.
The PPTV N55 power board uses a black PCB board, covering the area is more objective, and the material is also very solid. A plurality of thermistors and electrolytic capacitors are provided in different module areas, providing a more stable and secure circuit for the entire power board, and the transformer also provides a stable energy source for television.
The T-CON board, that is, the liquid crystal drive board is also one of the core modules. Its role is to process and control the signal sent by the core processor, and then transport to the liquid crystal panel, and finally present an image. The integrated circuit on the drive board is the master chip and microcontroller.
The input interface of the drive plate is connected to the TV motherboard master new disk, and the output interface is connected to the liquid crystal panel by two signal transmission cables. These three cables should also pay attention to the buckle at the interface when plugging. , Remove the cable after opening the snap.
PPTV N55 TV drive board uses LG's original master chip, the chip is clearly labeled LG Display's words, which is TLI2380EP, which is also the chip used in most domestic TV, compares the mainstream.
From a whole, the power board of the PPTV N55 TV provides a stable current, providing a good stability to the entire circuit through a solid material; and also selected a more reliable LG Display master control on the liquid crystal drive board. The chip ensures the image processing power of the TV, and the entire hardware configuration meets the mainstream level.
PPTV N55 TV other hardware disassembly
The PPTV N55 uses a separate WiFi module, 2x2 dual-double antenna design, and supports 2.4GHz and 5GHz dual-band WiFi signal reception, supports 802.11ac protocol, the theoretical networking transceiver speed can reach a propongor.
On the Bluetooth module, built-in Bluetooth 4.1, and supports downward compatibility, which can be combined with other Bluetooth + wireless network modules, and other radiofrequency work together, wireless connection capability is very strong.
PPTV N55 has a 9.9mm slim body, and it is not easy to take care of the sound quality in ultra-thin morphology. From the internal structure, the PPTV N55 has left enough space to the sound portion, and the JBL-grade speaker also supports Dolby Dolby sound. From the above figure, we can also see that the sides of the speaker have also been shocked, and there is no detail.
In terms of 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.
The process of PPTV N55 TV can be said to be very smooth, which is unsolute relationship with the reasonable design and layout of TV. From the internal structure and hardware material configuration, the PPTV N55 is never stacked cottage products, all parts and core components come from mainstream manufacturers, and the control is also satisfactory.
Although the previous Internet TV market is mixed, in order to reduce the price, it will reduce the cost of the Internet TV, and the quality of the Internet TV has been covered with a shadow. However, under the major trend of consumption upgrades this year, Internet TVs that are used to competing for low-end markets have also begun to transition to high-end high-end. In fact, the author also pinched a sweat for the quality of the Internet TV before dismantling, but it is still more satisfied, it is absolutely strong and traditional brands. The entire TV industry can only get better and better in such a highly competitive environment, and the low-end inferior products are delanted, and the facts are not intended, and the final victim is still consumers.
