The Z4 aurora is connected to the T3S of the Dark Wanderer at the Polar Night. Because the photo location is not easy to place, it is very good to take photos together. The sound is very good, and the two match well.

After the connection, the display effect is good. It was taken in the daytime, but it was cloudy on the day of taking the picture.

The Z4 aurora is connected to the Dalong TV computer, and the video and sound are normal.

The display effect is also good.

Compared with the LCD TV in the daytime (with flashing light), the Z4 aurora is clear in color.

Compared with the LCD TV in the daytime (with the flash off), the color of the Z4 aurora is still clear. However, the overall situation is similar.

Advanced Level (Dismantling)

It has been such a long time since the Z4 aurora appeared, and the author has not found the dismantling article of the aurora, so the author would like to take the first dismantling of the aurora, hoping that Mian Dada and Lao Luo will not cut me.

Before dismantling the machine, be sure to do a good job of anti-static, and it is best to wear anti-static gloves. First, we need to remove the fixing bracket of the polar meter Z4 aurora, as shown in the red circle in the figure above, and then turn right according to the rotation arrow, and then open the bottom shell, which has been mentioned when installing the SSD.

Then we remove the screws that fix the hard disk, remove the hard disk, and then remove the shell screws of the polar Z4 aurora, namely the screws in the four red circles in the above figure. The screws must be put in place. The author found a grid and had better have more white boxes to distinguish the screws. If you can't remember, you can use the oral sequence paper to mark the screws.

After the screws on the cover of the Jimi Z4 Evoque are removed, we will use a violent disassembly tool. The author uses two PVC drivers to carefully disassemble the cover of the Jimi Z4 Evoque. Be sure to pay attention to the buckle, and do not use brute force to disassemble it. As shown in the figure, the front part of the Z4 aurora has been removed. It is a large disk made of black acrylic material.

The internal structure of the Jimi Z4 aurora is very compact from the top. The design is very reasonable and the workmanship is excellent. The upper motherboard is fixed with three screws, as shown in the red circle above.

Before removing the mainboard, be sure to remove the connecting line to prevent the cable from being torn, as shown in the red mark above. Remove the cable first, then remove the fixing screw, and then remove the motherboard.

Before removing the main board, let's take a look around and see the composition of the polar meter Z4 aurora, which is mainly composed of circuit board, light bulb, audio, cooling fan, etc

Pay special attention when dismantling here. This flat cable is a bit like the flat cable of a laptop. It is very fragile, especially the two fixing screws are very small. Don't lose them.

Take apart the connecting cable, built-in wireless cable, flat cable, etc. Since the cable of the polar meter Z4 aurora is covered with fixing glue, you must be extra careful when removing it. The author removed it at night, so you must calm down and remove the machine.

Well, the main board has been successfully removed. The workmanship of the main board is excellent, and the sorting of components is very good.

There is a component on the back of the motherboard with an aluminum heat sink. Is it a CPU? Continue to disassemble. Remove the two fixing buckles with red circles!

Before disassembly, check the interface of the upper motherboard, HDMI HD interface, USB3.0 interface, and wired network card interface

After the heat sink is removed successfully, it can be seen that it is coated with heat dissipation silicone grease. The rectangles around it are Samsung memory chips (4 * 512M), the top right corner is eMMC 16G high-speed memory chips, and the square on the right side of the CPU is chips (i-Chips) that can compensate the distortion of 4K projectors

Wipe off the silicone grease and no CPU model is found. However, according to the information provided by the manufacturer, we already know that the Z4 Aurora uses a 4-core 1.5GHz CPU. There is also a DLP chip in the figure as a DLP projection driver chip, and there is another GPU chip that the author has not found.

After the analysis of the motherboard above, continue to look down and see what else is there. Only here can we see the core part of the polar meter Z4 aurora. The Harman Carton audio, projector optics, projector cooling and motherboard power supply are all here.

The close-up of the power supply part was not very clear about the optical principle, so the author did not dare to continue to disassemble the later lens disassembly, because it was a product for evaluation, and it may need to be recycled.

Connecting cable between power supply main board and optical lens

Close up of Harman/Kardon audio from various angles, excellent workmanship.

The shockproof cushion of the audio system is super thick, which shows how high the requirements for sound quality are.

most Later, a picture of the installation was completed. After the installation, we must check several times before powering on. Otherwise, the main board circuit is easy to burn. We also need to ensure that all the screws are installed in place. Many friends take the product apart and then install it back Several screws were put down. It is suggested that those who have strong hand power and are brave and careful to dismantle the machine. After checking everything, do not rush to install the front cover plate with touch, power on it first, and then use the remote control to test whether it can start normally Always start the machine and then install the cover plate. When powering on, put one hand on the power line. If you smell the pungent plastic smell, cut off the power quickly to prevent further burning.

summary

extremely The MiZ4 aurora is a magic tool for family viewing, as well as a commercial weapon. Both the appearance of the packaging and the appearance of the Z4 Evoque itself have reached a very high level. Compared with similar products, it is only extremely high Reached this height. In terms of use, let alone the rich video sources of Mango TV, there are all kinds of high-definition movies. Moreover, Jimi Z4 Evoque is equipped with such a high-end remote control, especially at a price of 1000 yuan, enjoying 10000 yuan of merit The left-right trapezoid correction and remote control focusing are even better than other similar products. At present, the only thing that makes readers feel regretful is 3D glasses. The author is myopic, and it feels strange to wear this 3D glasses. I hope I hope the manufacturer can improve the glasses and make them more perfect.
