500 points to send Skyworth 19 inch LCD ghosting, what to do

If you have no problem with VGA, it proves that the TV is good, it may be that there is a problem with the terminal of the TV receiving cable TV signal, it has no problem processing other signal inputs, and there is a ghost in processing the cable TV signal, which means that there is a problem with this interface and the corresponding circuit, only by converting the cable TV signal into a VGA signal can solve the problem. Buying a TV box is the easiest way to do it. The TV box is the cable TV signal input VGA signal output,According to what you saidVGA, it's OK if it's okay。

Cheap and convenient, a lot of computer city.

Since there is something very clear, let me talk about some home remedies.

Have you seen a three-dimensional painting, the eyes need beans, will there be ghosting will it become three-dimensional, try the eye beans, if the ghosting can disappear. It's not good to keep your eyes peeling, right? d

Repair it,Or replace,Skyworth LCD TV is small and really loves to have a problem。

Repair down. I don't want to spend money to find a friend who can fix it.

In the event of ghosting, you must first make sure that there is absolutely no problem with your signal source and that each plug is connected correctly. The input signal through VGA is normal,It can only mean that your TV**input is normal。 Your TV should be in the middle of the circuit data problem,Adjust the data should be normal,You can only find the manufacturer after-sales,They have information,Other maintenance departments don't seem to have too complete information,Manufacturers are technically confidential。

Ghosting is a problem with the signal, not with the TV.

Or is it a problem with the signal or signal line.

You say that there is no problem with the signal connected to the TV, because the old CRT TVs do not have this problem, because they can ignite the pixels in an instant, much faster than the pixels of a flat-screen LCD TV, avoiding the generation of dark moments. As a result, the audience does not perceive the dark moments, but sees an uninterrupted continuous picture.

I've come across whether the setup is the same as yours. There should be no problem with the TV, you unplug the power supply first, gently unplug the wired plug connected to the TV, you see that there is a copper core in the center of the wired plug, you see that it is not right, wipe it with a dry cloth and do not get wet, and then plug it in from the new wired plug must be aligned. See if it works.

Maintenance is generally more expensive,More economical way,No need to repair,Buy a computer with a TV box,The volume is about half a DVD player,Sell computers where you sell about 200 yuan,One end input wired signal,The other end outputs VGA signal,Use a computer VGA cable to connect it,The only drawback is to add a device。

Professional-level solution: If the problem still cannot be solved, it is recommended to flash the program to try to solve the problem. If the problem still cannot be solved, the fault can be narrowed by replacing the existing logic board at hand.

Finally, let me declare that although there are some suggestions on the Internet that you restore the factory settings to solve the sound, this method cannot be said to be a mistake or anything, I said, if strictly speaking, if the fault is a factor on the motherboard, it may generally be caused by the factors of the main control chip, and the integration of the main control chip is now getting higher and higher, not only integrating the function of the ** decoding chip but also beginning to integrate the function of the audio decoding circuit, so in case this is the case, when the factory is restored, when the factory is restored, the success of the clearing, Hello, I'm hello, everyone, but when you fail, you have to think clearly, in case of failure, you have to find a maintenance point to repair it, so you need to weigh the consequences. A factory reset is not the wrong method, but this method also has a certain failure rate and whether you can afford the result of failure. It's up to you to measure it yourself.

The issue is not available.

Confirm that the TV is faulty and contact after-sales service to solve it.

The first step in this fault is to measure whether the power supply voltage of the logic board circuit is positive.

Often. If the above logic board circuit supply voltage is normal, then measure all the logic board, DC-DC voltage conversion circuit chip, whether the voltage to the ground at each output terminal is normal, if it is still normal, then the fault must be properly considered to change the logic board.

Call the 95105555 directly to let the after-sales service come to the door, please report for repair as soon as possible, and you can ask to replace the machine if you have repaired the same problem three times in a row! It's a chip problem in terms of TV reception! After coming to the door, please ask to open an appraisal form, and ask to open it every time you come to the door, so as to better protect your own rights and interests!

Take an old TV to connect the wired signal first,Eliminate the wired problem。 Look for Skyworth's after-sales service again and see what to say. If you shirk your responsibilities, go directly to the mall or 315

1. Poor ED filter, when the pole piece inside the EZM filter is poorly grounded, it will cause a part of the IF signal to enter the image directly through its distributed capacitance ahead of the main signal, so that the image will be ghosted.

3. Poor receiving environment or poor grounding shielding of high-frequency heads, such as tall buildings near the receiving point, the TV receives the reflected signal reflected back from the tall building while receiving the direct signal, resulting in image ghosting; In addition, if the high-frequency head is shielded or poorly grounded, ghosting can also occur.

Among them, LCD TV ghosting is more common:

First, check whether the power supply voltage of the TV is stable, if it is unstable, it will cause the screen to fade back.

3. When none of the above methods can be solved, it may be caused by the hardware failure of the TV, such as the screen or cable failure, internal circuit failure, motherboard and its parts failure, etc., it is recommended to contact the after-sales service of the TV for maintenance. I hope my answer can help you

Here's how to troubleshoot a TV with ghosting:

1. Turn on the color saturation of the TV to the minimum, if the image has ghosting, you should check the antenna input system, high-frequency head, etc

Whether the SAW filters and their shields are well grounded and whether the clarity enhancement circuit is normal. Conversely, if there is no ghosting in the image, check the luminance delay line (including the circuit elements around it) or the ribbonpass filter circuit element.

2. Measure and check whether the final stage of the TV or the accelerating electrode voltage is too low.

3. Use the resistance measurement method to confirm the suspected components, such as whether the picture tube is aging or whether there is leakage, whether the brightness delay line, resistance, etc. are open.

4. Use component substitution methods, such as high-frequency heads, acoustic surface filters, manifolds, chromaticity bandpass filters, and luminance extensions.

If the voltage and resistance measurement method cannot be used to confirm the defective time line and related capacitance, the replacement method can be used to check one by one.

5. For ordinary users, it is generally recommended to contact the after-sales service or professional maintenance personnel of the TV for comprehensive testing and warranty of the TV.

You can call the official customer service consultation,You can also go to the znds smart source hu TV forum to find the administrator for help,May you successfully solve the problem!

You can buy Skyworth 19L12IW model LCD,**1299 yuan,Cost-effective。

The effect is definitely not as good as that of a computer monitor! But it works!

The problem of the imaging tube, just buy it and go directly to change it, and repair it after buying it for a long time, otherwise it will hurt your eyes after looking at it for a long time. It is also possible that it is damp, and if it is damp, it will recover after turning on the machine for a while.
