200 points!! Hit the head and have a ghosting 200

Paralysis strabismus has double shadows when looking at things, but common esotropia does not have double shadows.

If both eyes see at the same time, it is a double shadow, and the double shadow disappears when one eye is closed, which is called binocular diplopia, which is more common. Long-term double vision in one eye is hidden strabismus.

If you see something in one eye, it is called monocular diplopia.; Monocular diplopia is more common in lens dislocation, cataracts, etc.

If there is double vision in one eye, the main consideration should be that the refractive error is not corrected; Monocular diplopia can be seen in traumatic iris root disconnection, traumatic lens subluxation, and intravitreal cavity C3F8 inflation after surgery. If there is double vision when seeing things in both eyes, the main reason is the problem of binocular vision, and the double vision of both eyes is caused by paralytic strabismus, among which abducens nerve palsy is more common and should be treated in time!

There are many items of monocular diplopia examination, and to determine that the problem of the eye muscle needs to be done in a qualified specialized hospital.

At the same time, it is necessary to check whether there is abnormal retinal correspondence, fusion force, complex image test, prism test, eye position test...

If paralytic strabismus is confirmed, surgery is considered for congenital disease to eliminate diplopia.

2.Fusion refers to the brain's ability to synthesize two identical objects and combine them into a complete impression in subjective sense.

3.Stereoscopic perception, which can be examined with an isovisual machine, is a more advanced binocular vision function. Hope.

Whether it's the forehead or the back of the head. In the case of the forehead, it may be caused by congestion that compresses the retinal nerves. CT is recommended.

Saw a doctor? Didn't the doctor say anything? **No? Without knowing your test results and not knowing your medical history, it is difficult to diagnose!

It may be optic nerve damage, brain tissue damage.

It is recommended that you go to a major hospital for examination. Maybe it's a vision problem.

Good luck soon**.

It's best to do an MRI to see if there is any damage to the cranial nerves, and it will take some time to recover if it is possible.

This may be oculomotor nerve damage, it is recommended to go to the hospital to see an ophthalmologist.

Had to do a head CT. When it is safe to do so. Go to an eye doctor for an optic nerve examination.

Do a CT scan, preferably an MRI. See if there is an intracranial hemorrhage that compresses the optic nerve.

Let's go to the hospital to see an ophthalmologist.

There are three aspects, one to look at the display, one to the system, and one is the graphics card . See if the display is wet, or the cable is wet, the contact is poor, if there is a spare one, try to change it, if there is still this situation, see if it is a problem with the graphics card Update the graphics card driver, have a spare graphics card or set the display, or change the graphics card to try. If this is still the case, then reinstall the system and see.

The computer is stuck and needs to be optimized and cleaned up It is recommended to use 360 to clean up and close unnecessary plug-ins to reduce the pressure on the CPU and graphics card.

It is recommended to reinstall the graphics card driver.

It's that the computer is too slow to react, and it is suspected that it is poisoned, and it is recommended to reinstall the system to try.

Indeed, as others say, there is a problem with the components of the graphics card and it needs to be repaired.

It must be broken if it goes on like this, and it won't take too long, so send it for repair.

Capacitors, so many you can see that there is a problem, not only those big ones, but also those small chip components on the PCB board of the graphics card, as long as they are all capacitors with the word C, how can we ordinary people know that there are problems. r is all resistive, just as small.

Besides, there are inductors, MOS tubes, they have problems, and it is difficult to see that they are aging, so send them for repair.

This is the problem of the main chip of the graphics card, do the BGA of the main chip of the graphics card, generally have to find a professional computer store to complete! It is possible to solve the above problems by doing BGA, but sometimes it will have no effect and hang up directly. It is recommended to directly change a high-end graphics card, the NV430 graphics card you are talking about is not GT, if it is GT, it is recommended that you change the graphics card!

GT is a shared virtual memory, which belongs to the low-end graphics card!

The graphics card is broken due to the humid environment of the host computer.

Lightning strike nature, the graphics card is broken.

The rat gnawed the cable to get rid of it!

The graphics card chip is not working, the screen is blurred, the graphics card is broken, buy a new one.

It is very likely that there is a problem with the graphics card driver.

There is a smaller possibility of a graphics card quality issue.

See if there are any screen adjustment setting options near the display of this book, such as brightness, contrast and other adjustment buttons, it should be to adjust contrast or degaussing or something like that.

Liquid crystal is basically this problem, otherwise how can there be an optimal resolution.

Here's how to fix it:

1.First of all, you can let the printer self-test to determine whether the printer itself has a hardware failure.

2.After that, do a variety of cleaning work, and if that doesn't solve the problem, print a test page under the window to determine if the printer driver is installed correctly, and check if there is a problem with the application itself.

3.If none of this can be resolved, check the surface of the replacement cartridge for scratches, whether the cartridge is damaged, and replace it with another cartridge that can be used normally for testing.

4.If the printing ghosting still occurs when using high-quality printing paper and original toner, then the cause should be that the surface of the heating element of the laser printer is damaged, and the toner sticks to the heating element, resulting in printing ghosting. When there is a hardware failure, it is time to send the printer in for repair.

Solution and steps:

First, let the printer self-test to determine if there is a hardware failure in the printer itself.

2.Perform a cleaning job, and if that still doesn't solve the problem, print a test page under the window to determine if the printer driver is installed correctly, and check if there is a problem with the application itself.

3.To see if there are scratches on the surface of the replaced cartridge, if the cartridge is damaged, and replace it with another cartridge that can be used normally.

4.In the case of using high-quality printing paper and original toner, the phenomenon of printing ghosting occurs, then the surface of the heating component of the laser printer is damaged, and the toner sticks to the heating element, resulting in printing ghosting, and the printer needs to be repaired.

Data extension: A printer is one of the output devices of a computer, which is used to print the results of computer processing on related media. There are three indicators to measure the quality of a printer: print resolution, print speed, and noise.

There are many types of printers, according to whether the printing element hits the paper, it is divided into impact printers and non-impact printers. According to the structure of printed characters, it is divided into full-character printers and dot matrix character printers. According to the way that a line of words is formed on paper, it is divided into serial printers and line printers.

1. Reasons for ghosting.

The imaging principle of the black and white laser printer is to heat and pressurize the toner attached to the printing paper through the heating component, so that the toner is tightly attached to the printing paper.

If the printed document is ghosted, the problem may lie in three aspects: first, the quality of the paper used; the second is the quality of the toner in the toner cartridge; The third is the failure of the heating component of the laser printer.

Second, the solution.

In view of the above three problems, the first thing should be reprinted with better quality paper to see if there is still ghosting. If ghosting persists, confirm that the toner in the cartridge is original**. In the case of using high-quality printing paper and original toner, the phenomenon of printing ghosting still occurs, then the reason should be that the surface of the heating element of the laser printer is damaged, and the toner sticks to the heating element, resulting in printing ghosting.

When there is a hardware failure, it is time to send the printer in for repair.

3. Cause of failure.

There are three main reasons for this:

1.Fill toner.

Some filling toner has a large gap with the original toner in terms of particle size, hardness, melting point, etc., which is very easy to cause damage to the heating component of the printer.

2.Paper issues.

In order to save paper, many users will use one side of the used printing paper to print again. When you reuse these papers, forgetting to remove the staples from the paper or not separating the paper that has been bound together can easily damage the heating component of the printer. Or some label paper, sulfuric acid paper, etc. are used in printing, and this kind of paper is also easy to damage the surface of the heating element.

3.Paper jam problem.

Paper jam is a common printing failure in laser printers, and the correct operation is to remove the printer's toner cartridge and then remove the jammed paper when clearing jammed paper. Otherwise, the toner cartridge will be easily damaged under the hard pull.

4. Preventive measures.

Since printer paper is often the main culprit of damage to heating components, high-quality printer paper should be used, taking care that the printer paper does not contain hard metal objects. Stuck paper should not be removed violently, and the toner cartridge should be removed before removing the paper.

This is my specialty, if the calibration of the nozzle is not good, then repair it according to my method,,, I really don't want to say, this is also a trade secret, but if you can give a few more points, it will be considered that I will not leak a secret in vain, the method You open the left cover, there are two roses in the back, and then there are two cards under the cover, pry them one by one with a flat-mouthed small compass, after opening the cover, use alcohol cotton, get less alcohol, and clean the transparent; Disc, and then print it and try it, for sure, oh yes, and help me keep it secret, I used to be a manager at the Epson pit, don't tell anyone. Well, don't remember to add some more points.

1.Check the printhead, if it doesn't work, it is estimated that the paper-moving parts are broken.

2.Hardware problems, not enough lubrication, that is, there is resistance! (If it is left and right ghosting, it would be good to calibrate the nozzle, if it is front and rear ghosting, it is a matter of the feeding wheel and the grating disc).

Turn off the software and reopen it to see.

The computer is stuck, send the configuration over to see.

There is a problem with the graphics card or screen, if there is a problem with the screen, most of it is a problem with the screen line.
