To make a long story short, here's one for everyone: 
Here we need to first remove the pole Z4 Aurora fixing bracket, according to the above red circle box to disassemble the screw, of course, need to open the pole Z4 Aurora bottom shell in the direction of the rotation arrow. 
Polar meter Z4 Aurora Intelligent Projection Dismantling
The Z4 Aurora Smart Projector has already been tested by many people in terms of out-of-box and system content. It will not be repeated here. Today we will present the whole-body anatomy of the Z4 Aurora. Everyone presents a real and natural polar meter Z4 Aurora. Tips: Before disassembling the machine, be sure to take anti-static measures and wear anti-static gloves. After that, we must remove the hard disk. First, we must remove the screws that hold the hard disk and remove the hard disk. In the case of the Z4 Aurora shell screw removed, is the position of the four red circles in the figure, must be placed. I found a white box to distinguish the screws, and I couldn't remember where the screws were, but I could also mark them with mouth-sequence paper. After removing the Z4 Aurora shell screws, start using a couple of PVC drivers to remove the Z4 Aurora case a little bit carefully. Be careful not to use brute force. This guarantees a very good Z4. Aurora shell integrity. The picture above shows the effect of removing the Z4 Aurora shell from the front, with a large disc made of black acrylic material in the middle of the front face. The figure above shows the internal structure of the Z4 Aurora. From the overall point of view, the Z4 Aurora Projector is very compact and has a very reasonable design with detailed workmanship. The upper board is fixed with 3 screws, as shown in the red circle. Prior to dismantling the motherboard, the Z4 Aurora Aurora must be removed to prevent the cables from being torn. Just like the red circle above. In other words, you need to remove the cable first, and then remove the fixing screws before you can completely remove the motherboard. However, before dismantling the Z4 Aurora Motherboard, we can see the general composition of the meter: the circuit board, the bulb, the sound and the cooling fan, which is basically the overall configuration of the Z4 Aurora. It should be noted here that the cable of the meter is a little bit like the laptop's cable, which is very fragile and must be removed with care. In particular, the two fixing screws are small and must be put away. Do not lose them. Because the pole Z4 Aurora cables are fixed with glue, be sure to take extra care when connecting the Z4 Aurora cable, built-in wireless WIFI module, and cable. There is a need to calm down here. Extremely Z4 Aurora workmanship is very good, and the sorting of components is also very good. This is the effect of removing the motherboard. On the back of the motherboard there is a component with an aluminum heat sink. Is it CPU? To continue the demolition, you need to remove the two red circle fixing buckle! Take a look at the interface above the motherboard, HDMI HD interface, USB3.0 interface, wired network card interface. The cooling fins were successfully removed and you can see the thermal grease coated on them. The rectangle around them is a Samsung memory chip (4512M), and the top right corner is an eMMC 16G high-speed memory chip. The square on the right side of the CPU is The chip (i-Chips) that can compensate for the distortion of the 4K projector. We did not find the CPU model after wiping off the grease, but from the information given by the manufacturer, we already know that the Z4 Aurora adopts a 4-core 1.5GHz CPU. There is also a DLP chip for the DLP projection driver chip on the picture, and there is also a GPU chip I did not find. After the analysis of the above main board, continue to look down to what else, to see the core part of the polar meter Z4 Aurora. The Harman Kardon audio, the projector optics, the heat sink of the projector, and the motherboard power supply are all here. Close-up of the power supply part, because the optical principle is not very understandable, so later lens disassemble, there is no dare to continue to split, because it is to evaluate the product, it may be recycled. Finally, to complete the installation of a picture, after installation, be sure to check a few more times, and then power. Otherwise it will be a very serious situation, the motherboard line is easily destroyed. It is also necessary to ensure that the screws are installed in the correct position to prevent incomplete conditions in the projector. And many people do not develop good habits when dismantling, it will let the polar meter Z4 Aurora smart projector feel missing arm and leg. Therefore, it is recommended that people with strong hands-on ability to dismantle the better. After inspection, do not install the front cover first, then turn on the power first and try to use the remote control to boot normally. After the normal boot, install the cover. If you put your hands on the power cord after power on, you must smell the pungent plastic smell and cut off the power quickly to prevent further burning.
