Teach you some common sense of purchasing machines:
At present, in general, we should pay attention to the following points:
1, UMD warehouse seal; Check the screen for bad spots and dust; Whether the fittings are converted to assembly; The key problem (this is the problem of early futures, and there is almost no key problem in PSP now), the sealing of UMD warehouse cover is only an aesthetic problem, because the switch bayonet is on the right, so the left side is more or less loose, so it is not too harsh.
2. Next, check the bad points of PSP LCD. PSP adopts Sharp high quality16 million color AVS LCD screen. There was a time when it was said on the Internet that the PSP would enable the Samsung screen. However, I can tell you responsibly that PSP still uses Sharp's screen.
3. Speaking of bad spots, let's first understand the definition of bad spots: pure black spots in the case of white screen or pure white spots in the case of black screen. When switching to the red, green and blue display mode, this point is always in the same position and always a pure black or pure white point. This situation shows that the three sub-pixel points of the pixel, R, G and B, are all damaged, and such points are called bad points. Generally, the small bright spots on PSP are mostly pure white under the black screen. This point is hard to find, but it does not affect the normal use. It is acceptable if there are only three or so small bright spots on the PSP. Of course, we have the right to pursue perfection.
Buy a memory stick when you buy a machine. I recommend the Sony stick with high cost performance to everyone. Many people are worried about the quality of these sticks. In fact, the quality of the stick is good except that the shell material and printing are a little worse than the original one. Moreover, now all the rods are provided with 1 year warranty.
4. Experience in purchasing films. PSP film must be posted, and everyone doesn't want their love machine to become a flower face. At present, there are many models of various films on the market, including imported original films and domestic films. The representative one is Japanese HORI film, but now the original film of HORI is hard to buy, and most of the films on the market are assembled. If you can't buy the original HORI membrane, the quality of domestic high-end membrane is good, and the price is not cheaper than that of 40 yuan.
