Hello, everyone. Welcome to Love Demolition. I'm Koala. Some time ago TCL launched its new Internet sub-brand, Thunderbird, and the brand's smart TV Thunderbird I55 also appeared. For the new brand, it is hard to avoid doubts. What is the internal structure of the Thunderbird I55? How to use materials for work? For a long time, I didn't tear down the TV. I happened to have a real machine in hand. In this issue, we took it and started to find the answer through dismantling.
Dismantling the whole show...
After watching Thunderbird I55 dismantling the whole process, let's talk about some key points:
1, because the TV head is relatively large, so need a larger venue to dismantle, and this big guy is far more difficult than the mobile phone, one can not complete. In the process, there are more places to pay attention to. Screws are larger than mobile phones, and the tools used are different. Before the dismantling of screwdrivers for mobile phones, it is no longer necessary to use larger screwdrivers and household tool boxes. Replace the screwdriver.
2, in the step there is a similar place with the phone, in fact, from the overall perspective, but also the back cover, motherboard, screen, only the size of the components, the internal structure slightly different
3, when dealing with the back cover, the screw is obviously much more, need more careful and patience
4, start with the back cover to start, according to past experience, koala is expected to get all the fixed screws, the back cover can be easily removed, but it is not the case, first there are a large number of left and right clips, and the panel roll cage Fastened together and very tight. The structure is also different from the mobile phone buckle. The thin and hard metal wires are arranged on both sides of the roll cage and the hooks are hooked on the top. This brings great difficulty because it cannot be seen from the outside, plus the buckles. It is very hard, brittle, and poorly malleable, so it needs to work hard, otherwise it will break easily. The bigger difficulty comes from the top. It's not snap-fastened. Instead, it uses a very wide and thick double-sided tape. It's definitely not open. It can only be heated and reprocessed. The TV has to use the wind, which was not encountered before. Then found that because the TV back cover is very thick, and it is a plastic material, virtually inevitably upgrade the difficulty, the wind ** temperature is too high, the shell will be deformed and burned, the wind ** temperature is low, the heat is not enough, roasted not Throughout, the final adjustment to 150 degrees, let the double-sided adhesive soft, and then cut and separated with a knife to be considered open, this can be said to be one of the most difficult steps in the I55 dismantling.
5. After taking down the back cover, the structure inside the TV is clear, and with the different main and sub-boards of the mobile phone, the size of the two circuit boards inside the TV is similar. From the perspective of the smart TV, this structure is as expected because Most of the integrated smart TVs are like this, and the millet TV 3 has a slightly different split style.
6. The left side covered with black metal is the circuit board that is responsible for the intelligent part of the TV. You can understand it as a built-in TV box, or smart hub, including USB, HDMI, and cable interfaces. Most of the interfaces are integrated in this one. On the circuit board. The other board is mainly the power supply, as well as image processing, signal output, and so on.
7, before removing the circuit board, you need to disconnect the appropriate cable, Koala found I55 cable has two problems, the first is scattered, the line body itself is not neat and loose processing, including the quality of the connector Not high; Second, the bottom of the line is messy, and are fixed by tape, looking slightly casual, mainly the speaker's line, giving the impression that a little harder.
8. The main body of the connector of the TV base is made of plastic material. The internal bolts and brackets are metal. In order to ensure the stability of the base, the area of ​​this part is relatively large;
9, from the official website parameters, I55 stereo speakers, and Dolby and DTS audio blessing, but just look at the speakers of this part, the details are slightly rough, after getting started weight is also floating.
10, the bottom breathing light is removable, the structure is not complicated;
11, want to remove the panel, it is necessary to first solve the outside of the metal frame, this time there is no double-sided adhesive, is completely screw, of course, have to change the screwdriver. It should be noted that the lower one of the metal frames can be removed separately, while the left and right sides and the top are integrated. However, after the removal of the metal frame, it was found that it was still not enough. There was a plastic frame at the bottom, and the metal roll cage on the back had to be handled.
12, finally can remove the panel, this is another difficult point, because it is far larger than the size of the mobile phone screen, you can break it without paying attention to a little, fortunately this piece of screen scalability is not bad, lift even the moment feel It is not like glass. The whole screen has a certain degree of curvature. It should be an embedded LED from the outside. As for the white side of the roll cage, it is a backlight module.
13, look at the chip part, the largest chip on the circuit board is the Mstar838A processor, using a quad-core A53 architecture, clocked at 1.7GHz, GPU is Mali T820 MP2, next to four with M logo is a magnesium flash memory chip, As for writing a number 6 with a pen in the corner, it is a 16GB eMMC 5.0 memory chip.
14, the type and number of screws are very many, the light storage box uses two, if not classified collation, recovery is very easy to force, and some screws are relatively hidden.
15, the surrounding metal frame material enough, but the effect of chamfering and CNC grinding less refined, including surface coloring, lack of smart TV should have a sense of science and technology, compared to smaller meters and LeTV there is still a certain gap.
As for its evaluation and summary, we just look at the scores just fine.
