I m ready to buy PSP, I don t know what to pay attention to when buying There is also the problem of

The PSP2000 is probably around 1450. 4G stick is about 190.

The residual image problem you mentioned generally exists on LCD screens. But it's not really serious, most games don't have this problem anymore, it's just that playing games or watching movies at night is not good for the eyes. This is a normal problem.

Geographical issues, so you can only refer to the price.

The general position is between 1350-1400, and if it is high, it means that JS makes it black.

Sticks Red Sticks 230-265 Black Sticks I don't know what more than 100 pieces look like.

In fact, the black stick is also good, **cheap, if you can ignore the extra few minutes spent copying the game, you can choose the black stick.

Slowing down? Generally, it is the file format of the memory card, and if you choose fat32 when you want to format it, it may be a problem with CPU speed, but this is generally unlikely.

You can try it in the store before you buy it, and you can find that it is slow and call js to help you solve it.

Finally, go to some video game forums and look at the posts to make up for the lessons, refurbished machines, assembling batteries, and the like.

Group stick 200 or so can be bought, try to try a few more, drag is generally more obvious in winter, because it is an LCD screen, it is more normal, buy PSP2000 when you just see if there are any bad spots.

Normally, the machine is 1450, and the 4G high-speed bar is about 230.

Hello landlord

It depends on what type of PSP you buy!

There are 4 models of PSP, one is called: PSP1000

One is called: PSP2000

One is called: PSP3000

The last one is called: PSPGO

When buying, pay attention to:

1. There are no dead pixels in the PSP screen.

Common to all models).

2. Is there any scratch on the outside of the PSP memory stick card slot?

Common to all models).

3, buy PSP3000 or 2000V3, you have to see if the system version is, if it is lower or equal to, then you can buy it with confidence, because 3000 and 2000V3 current or below the system can be cracked

If it is higher than. Then don't buy it Because you can't play if you buy it, and you can't crack it if it's higher, then wait until the later version is cracked before you buy it At that time, the ** won't be much higher Landlord, please rest assured. Complete.

Pay attention to see if the accessories of the PSP are original, such as headphones.

In-line control. Memory card (group card or original).

See if it's a refurbished machine.

For example, whether the body is scratched.

or whether there is ash in the keys.

Then the most important thing is to see if the screen has a dead pixel bright spot.

Mainly prepare a few primary color maps. Red. Green.

Blue. Black. White. After opening, pay attention to the screen from all angles.

Whether there is a side light leak.

Or there are colored dots (colored dots) on the screen

Particularly bright spots (highlights).

Or you can't display colored dots (bad dots).

Then there is whether it is not disassembled.

Check whether the number on the PSP matches the number on the box.

PSP3000 is generally not much of a problem, first go to the Internet to see what the standard equipment is, whether you need a memory stick, understand your needs and then decide what accessories to buy. Just look at the battery, screen dead pixels, key edges, remote sticks, memory card sockets, and whether there are signs of wear on the edge of the screen, especially the transparent L and R keys, which are to be passive, relatively easy to detect. There is a white sticker on the right side of the bottom of the host with three dashes connecting 4 groups of numbers, and the middle two groups of numbers must be consistent, which is consistent with the numbers in the battery compartment of the machine, if it is not right, or the sticker has signs of damage, such a machine must not want.

Pay attention to whether the printed words on the power supply are blurred, and whether the gloss of the words on the battery is uniform is also a link that cannot be ignored.
