I haven t watched the TV for half a year, and today I plugged in the inner screen, what happened?

After the LCD screen is collided by an external force, it is not energized and there is no obvious damage, unless the force is too great.

If the inner screen shows obvious traces of external force, it is a collision break. No, it's the quality of the screen.

Can you fix the LCD TV display screen if it is broken?

Hello! If you are sure that the LCD screen is broken, yes.

There is no way to repair it, it can only be replaced, and the replacement of the LCD screen is generally 50% of the whole TV**-about 60% of the capacity, therefore, many people have given up repairing because of ** factors and replaced with a new machine. In addition, if the LCD screen is not hard damaged, but the black screen does not necessarily mean that the LCD screen is broken, so it is best to contact the after-sales or maintenance personnel to help you check it before making a conclusion.

Answer: The damage to the inner screen of the LCD screen is purely physical damage, and the manufacturer has no way to repair such damage, so it can only be solved by changing the screen.

It's not cost-effective, a TV of 1,000 yuan, and the screen is worth 800

If the LCD TV display is broken, it generally cannot be repaired or repaired. There are two kinds of LCD TV displays on the market, one is LED and the other is LCD, these two products can be said to be the core components of the TV, accounting for 50% to 70% of the cost of the TV, and it cannot be repaired when the TV has these faults, and it must be repaired at a special maintenance office.

LCD TV display features

LCD TVs also have soft screens and large screens,This is also selected according to the customer's own preferences,Soft screen or hard screen is just a different process,Each has its own characteristics,There is no fundamental advantage or disadvantage。

But the quality of the LCD TV screen is very important, because this is related to the feelings of our **, as I just said, there are two main types of displays on the market, LED and LCD.

They have their own advantages and disadvantages,Everyone is mainly based on their own preferences when buying,If the screen is to be replaced,Everyone should be psychologically prepared,LCD TV screen replacement accounts for half of the TV**。

The possible reasons for this situation are: the TV is caused by moisture and other reasons, the screen is broken, there is no human impact, and there is a crack in the inner screen, then open the inside of the TV to see if the internal circuit capacitor is burst and the display screen is damaged.

Solution to damage the inner screen of the LCD TV:

1、There is a situation where the TV has not been turned on for a long time,It may be considered that the display content of the display screen is abnormal due to moisture,The inner screen seems to be broken to the naked eye。

2. The screen has obvious traces of breakage but the crack is not serious, and the screen can still operate normally, since the TV can be used normally without being affected, it is not recommended to repair it.

2. The screen has obvious traces of breakage and serious cracking, serious breakage will be conducted to the homogenizing plate behind the LCD screen, so that the light guide sheet is broken at the same time, then the screen can not be displayed, at this time it is recommended to seek professional after-sales service personnel to repair the screen.

Note: According to the relevant regulations of the state, if it is an LCD TV.

The whole machine has a one-year warranty and screensaver.

There is a three-year warranty. Generally speaking, the repair work of the TV is limited to the motherboard on the back of the screen and the fault repair caused by the wiring. Because the body of the TV screen is getting thinner and thinner, the screen panel that fits the design cannot be repaired, and can only be replaced as a whole, so if the inner screen is damaged, it is generally not possible to replace only the inner screen, but the display screen needs to be replaced as a whole.

1. If the display screen of the LCD TV is broken, it generally cannot be repaired or repaired, because the difficulty of repairing the display screen is high, and the value of repair is not high.

2. The display screen of the LCD TV is the main component of the LCD TV, which usually accounts for six or seven percent of the whole machine, so the cost of changing the screen will be relatively high. If the TV has been used for a long time,The cost performance of changing the screen will be relatively low,In this case, it is better to buy a new machine directly。

If the inner screen of the TV is broken, it is usually necessary to replace the entire screen to repair, and the cost of this repair will be high, which may be close to the purchase of a new TV**. Therefore, if there is a problem with the inner screen of the TV, it is generally recommended to buy a new TV to replace it. Of course, before determining that there is a problem with the inner screen of the TV, you can first try to do some basic troubleshooting, such as checking whether the power and signal cables of the TV are well connected, trying to restore the TV to factory settings, etc., to confirm the root of the problem.

If none of the above solves the problem, then you may need to consider replacing the entire screen or buying a new TV.

The reason may be that water has ingress inside the screen, and you can use a clean soft cloth to dry the moisture inside to solve the problem; The reason may be that the screen is subject to external vibration and shaking, and some protective measures can be set around the screen to guess or solve the problem; The reason may be that the screen has been used for a long time and there is an aging situation, and the screen can be replaced to solve the problem; The reason may be that the current of the picture tube bundle is too large and the protection circuit is caused by it, you can turn on the power switch of the TV, and listen carefully to whether the back cover of the TV has a high-voltage sound of turning on. If there is an indication that the circuit is normal, if not, it means that the circuit is not started, you can seek the help of professional maintenance personnel to solve the problem.

Common faults of TVs:

1. There is only sound and no image when the TV is turned on: the reason may be the fault of the high-frequency head, and you can check whether the relevant parameters of the high-frequency head are normal. If it is not normal, the image will not appear on the screen, and replacing the high-frequency head will solve the problem.

2. The TV is not energized: the reason may be the power failure outside or in the machine, which can be solved by replacing the broken parts. But if the driver board is damaged, you need to use a universal meter to check whether the power supply related to the power supply is normal, once the driver board is damaged, it will cause the two groups of power supplies to have no voltage output, if the voltage is faulty, you can judge that there is a problem with the driver board, contact professional maintenance personnel to repair it can be solved.
