As a user who used to have nearly one year in the extremely powdery and ultra-thin Z4Air, but encountered more than 5 months of maintenance and replacement, and until the end of the last meter rice official still did not solve the final problem, so I think it's time to give it to the nearest The friend who bought the Projection Project had a little advice.
The earliest understanding of polar meters was a buddy's home two or three years ago. At that time he participated in the crowdfunding Z3 crowdfunding to get the first generation of Z3 products, the first contact with such an exquisite and compact micro-investment feeling is still quite amazing, the function and color is not bad. But because the family already has an ordinary projection, it does not consider buying it. During the same period, several colleagues and friends were also recommended to purchase the Z3's several generations of products.
Later, the projection of the home was aging, so we started with a Z4Air. The biggest problem in the first half of the year was on the remote control. Sudden failure resulted in the replacement of four remote controls. Finally, the meters themselves will use the button battery remote control. It was finally solved with the No. 7 battery, but the real nightmare only started after six months.
After six months of use, suddenly the projector failed to boot, so he sent back the poles for repairs. After half a month of tossing, he finally repaired and sent them back. However, the unlucky change process began. After the sale of the meter, after repairing the machine, the Z4Air lens cover is not returned, resulting in a large number of lenses into the ash. The socket and the fuselage are not individually packaged. When the mail is sent in the box, the friction between the boxes causes the aluminum shell body to wear multiple times. Extreme customer service argued after the fight and agreed to change.
Originally thought that the problem was finally resolved, but after the replacement, a series of problems followed. The first is that there is an issue of automatic flashback in the playback video. This flashback is random, and it does not determine what format source and time. There may be no problem playing a few movies, and there may be flashbacks in several consecutive movies, and there may even be a few flashbacks in one movie. Feedback customer service feedback after strong brush about the latest firmware will be able to solve, but according to the customer service provided by the brush pack after flashing brush still exists. In the end, it was impossible to solve the problem. It was suspected that it might be an individual hardware problem. Extremely agreed to change the machine again.
It was mailing back and forth for two weeks. Once again, I got the machine boot test and flashback still existed. This time, Mami pointed me at the problem and doubted the hard drive I was using. At first, I thought it was reasonable, but after I test the Z4Air with 5 or 6 different brands of mobile hard disks, each hard disk has a problem of flashback, which should be basically determined. This is not a hard disk problem. Once again contact the customer service, get the feedback is likely to be the source of the film, I suggest that the source will be turned into MP4. This time I am more puzzled, the machine is not annotated to decode N multi-format it, how to turn the film source into MP4, do I buy a Taiwan MP4? And some of these sources are seen in the first half of the year I used the first bad machine, and half a year's time did not appear to have flashback problems. From this I began to suspect that this batch of machines from Kamitsu was purely hardware-influenced, and then replaced again after many consultations.
After two replacements, the pole meter started a delaying strategy. After I mailed back to the problem machine, I was delayed to say that Z4Air was out of stock and could not be replaced. We had to wait for the goods to change. One week is another week, asking again, still said out of stock. This time I was wise to drop out of school. I immediately went back to the Tmall shop of the Mimi and asked if there was any goods in the Z4Air. I got a reply and I can ship it that day. After I sent the screenshots with Tmall to the post-sale customer service, Mami talked for a long time to show that they were separated from the Tmall after the sale, so I didn't know their interpretation of the goods. This time I would like to ask what medicine is sold in the polar rice gourd? Hey! This year's shortcomings will be played by people. After playing a spy game with the customer service team, they received a new machine the next day.
After getting the machine, he will start to work as a tester. How much I hope that the two machines are cases! However, this third aircraft still did not escape the fate of flashback. How endless it is, I have begun to suspect that I do not have a bunch of hard drives on the Z4Air this tall micro-investment? At this time I suddenly thought of my friend Z3, so I took the machine and the hard drive to my friend. I used the Z3 to test my hard drives and those flashbacks. Ha ha, that Taiwan used a two-year flashback Z3 ​​did not return, then use Z4Air measured flashback. This time it was a drop-off, hard disk and film source are no problem, the problem is on that damn Z4Air.
Simply combing the logic, the problem is obvious. 1, this machine I was used for six months broke, before the bad flashback has not been a problem, this issue is a new machine. 2, I used more than one mobile hard disk test has this problem. It must not be a hard drive problem. 3. Assuming that my hard drive has problems, but I used the same meter Z3 to test the same hard drive did not appear such a problem. It can basically be concluded that either hardware or system problems.
When the problem is clear, the pole rice still says that their product has no problem. Then another round of chat with the customer service. I will say that I used the same Z3 test as Z4Air. But should the new machine not be better than the old one? After a while, I said that there are still problems with my film source. Let me put them on the two test strips of MM dancing. But I bought a projector to see the test film? One will say that it is still a problem with the hard disk, or you will insert a USB flash drive later. But I really didn't have much money to buy a 1T U disk for the movie. In any case, I don't want to solve this problem again. In the end, I will ignore me directly.
Of course, the rights and interests need to be argued energetically. A few days later I contacted Mami customer service again and asked if I suspect that there is a problem with my hard drive, I am willing to purchase a brand new hard drive for testing according to the requirements put up by Mimi. This time, Mami is guilty. In any case, I do not accept my request. Finally, I was forced to try to brush the system firmware to the earliest version, and the turn of the matter came. This attempt was just a real flashback problem on the Z4Air system. When the firmware brush to V1.5.4 version, flashback problem disappeared, but the BUG of the old version of thermal shutdown also appeared, and then upgrade to V1.7.5, flashback and overheating problems are resolved, at the moment the real tears Yeah, finally watching movies in peace! Since then I have repeatedly tested the V1.12.9-V1.14.9 firmware released from my first machine after it was broken.
The problem that has bothered me for more than 5 months has finally been found, but it cannot be said that the problem has been solved, because now it only solves the flashback problem, but since the VIP will be upgraded to firmware seven times after V1.7.5 There must be some problems that need to be resolved in these upgrades, but it may not be so obvious than such intuitive issues as overheating and flashback. What I found most puzzling in these five months was that where did the confidence of the dinosaurs push the question to the consumers and they never thought about the problems of their own products? I have heard that there are hammers and quails in the office of the Grand Michao, and it seems that there is no matter what kind of hammer is a marshmallow.
Prepared to start the dual-11 micro-cast friends, watching my Z4Air maintenance Zimi 5 months hard, and until I send a draft so far still did not solve the new firmware flashback problem. Then consider what kind of product you choose, or what kind of brand, after all, you do not want to buy a projection to see the half-year repair it.
