The TV screen is black, how much does it cost to repair it, thank you

The TV screen is black, and the repair cost is about 300-1000 yuan.

The LCD TV has a black screen, maybe the power drive board is broken, maybe the backlight is broken, and the display screen is broken, only the master checks it**. If the driver board or lamp is broken, it only takes about 400 yuan,It is not recommended to change the display screen,Directly replace the new TV。

There are several cases of a black TV screen, and the situation is different, and ** is not the same:

One may be that the backlight is not bright, the power board or backlight driver failure, the maintenance **100 yuan or so, the second may be the logic board failure, the maintenance **150 yuan or so, the third may be the motherboard failure, the maintenance **200 yuan or so, the fourth may be the COF fault on the screen edge strip, the maintenance ** is about 200 yuan, the fifth may be the screen is broken, there is no maintenance value.

The above situations can be used as a reference.

This depends on what is broken, ** each place is different, one yuan is more than 100 to a little more than 200,

LCD TV display, if the power supply is broken, repair a few hundred yuan, the backlight is also a few hundred yuan, if the LCD screen is broken, don't repair it.

LCD TV black screen,The vast majority of the backlight strip is damaged,The price of the light bar is the size of the TV,And the number of light strips,There is a big difference。 Therefore, it is difficult to answer,

There is more than one reason for the black screen of the TV, and the maintenance ** is also different, so the maintenance ** cannot be accurately judged.

Summary. If our TV has a black screen,Then the repair** is about 50 yuan to 300 yuan,It depends on what the damage is,If it's just that the screen cable is not connected,Then the maintenance price is not very expensive,If a very serious failure occurs,Then the maintenance cost is very expensive,If we think it's not worth changing a screen,It is recommended that you change a TV。 If our TV has a black screen but there is sound,Then the maintenance will be about 200 yuan,Specifically**You can consult the relevant maintenance personnel,It is worth noting that,If our TV is still within the warranty period,Then we can ask the maintenance personnel to repair it for us free of charge,You don't have to worry too much,The general TV failure repair master will deal with it quickly。

When we use the TV,If the TV has a black screen,Then it also needs to be repaired,Generally, the maintenance of the black screen of the TV is about 200 yuan,But the specific** still depends on the reason for the black screen to decide,If you need to replace the accessories in the TV,Then the repair of the black screen of the TV will also be a little more expensive。

If the TV has a black screen,Many friends are very worried,We should all go to repair it often,The TV has a black screen and sound,The maintenance may go to about 200 yuan,You should immediately contact a professional after-sales master to come to the door to test the specific problem。 If the TV is still under warranty,It's free door-to-door repair,So you don't have to worry too much。

In our home,We will definitely watch TV when we are leisure,It is inevitable that the TV will encounter failures in the process of use,For example, the TV has a black screen but there is a sound problem,This is often due to the failure of the display screen of the TV,If you want to repair,It generally takes about 500 yuan。

To this fault, first measure whether the voltage of each group at the output end of the main switching power supply circuit is normal. If the above measurements are normal, this means that the switching power supply circuit is not faulty, otherwise it is a problem with the switching power supply circuit. At this time, in the measurement of the backlight drive control circuit chip, whether the voltage of each pin to the ground is normal, if there is any abnormality, check the components around the abnormal feet of the chip.

[If the above faults are repaired, the price of 300 yuan and 350 yuan will be obtained].

TV black screen maintenance** needs to be checked to determine,LCD TV black screen is divided into no display and no boot,There is no sound and no image, it is not displayed,Not displayed is the LCD screen and backlight problem,Or the motherboard boost circuit is faulty,The sound is not turned on,It is the motherboard or power strip failure,Maintenance**More than 200,The higher the value of the TV, the more expensive the maintenance cost。

In this way, if the display is damaged or the controller is damaged, the control system is cheaper if it is fast, and if the screen is damaged, it is better to buy a new one.

It depends on the situation.

TV black screen repair**need to see what brand your TV is,What model,Different brands and different models correspond**It is also different。

Hello, the repair cost of LCD TV black screen is generally more than 50 yuan, if the chip is damaged, it is generally about 150; If the switch tube, large filter capacitor, or power supply regulator are broken, it is generally around 80. But because of regional differences, ** will also vary. You can also provide your specific city to recommend repair information that is close to you.

Summary. Hello dear, it's a pleasure to serve you. LCD TV black screen repair,**About 200 400 yuan。 It depends on the failure of your TV.

How much does it cost to repair the black screen of an LCD TV?

Hello dear, it's a pleasure to serve you. LCD TV black screen repair,**About 200 400 yuan。 It depends on the failure of your TV.

1.If your LCD TV is damaged by an external impact. Or the cable on the top of the screen is damaged and oxidized. In this case, there is no repair value. Because the repair cost is about the same as buying a TV.

2.If it is only caused by the fault of the energized line. This repair is very cheap. All you need to do is power the circuit.

3.If it's a problem with the motherboard. In this case, it should be divided into logic board and power board, ** generally in 200 400 yuan.

4.It is also possible that there is a problem with the light bar inside the TV. In this case, it is necessary to replace the light bar or repair the light bar voltage. **Generally around 200 yuan.

There are many reasons for the black screen after the TV is turned on, such as the problem of the motherboard, the problem of the backlight bar, and the damage of the screen itself.

Problems with the motherboard:If there is a problem with the motherboard of the TV,Generally, it will be on the switching power supply,The switching power supply of the motherboard is a circuit,Not a separate accessory,If there is a problem with this circuit,It will lead to a black screen after starting,Of course, it may not turn on。 <

If you understand the circuit board, you can directly repair the circuit board, you only need to replace a few electronic components in the circuit board to solve the problem, it doesn't cost much, if it is to replace the motherboard, you need to see how big the TV is, generally 30 50-inch TV motherboard is about 200 yuan, if the TV is bigger, then it's ** will be improved.

Problems with the backlight strip :According to the size of the TV, the number of backlight strips in the TV is also different, some TVs have four backlight strips, some are six, some are eight, or even ten more, the larger the size of the TV, the more the number of backlight strips. <

There is not much money for a backlight strip, probably a few dollars, but when the backlight strip is replaced, a few will be replaced, even if it is not damaged, it must be replaced all, this is because if it is not replaced, the brightness of the screen on the TV must be inconsistent, so if there is a damaged backlight strip, it must be replaced all. <

The screen of the TV is damaged:The screen of the LCD TV is divided into the inner screen and the outer screen, in the past, the screen of a TV will be very high, and even catch up with a TV, but recently, the LCD TV screen has declined, if you don't want to replace the LCD TV, then it is okay to replace a screen, generally about 40 inches of LCD TV, replacing a screen is about a few hundred dollars, but at present, the LCD TV is not high, So it feels like it's more real to replace an LCD TV.

Generally, it is an abnormality in the operating system, but it cannot be ruled out that it may be a hardware problem, such as a malfunction of the monitor and graphics card. If you reinstall the system, it won't be too expensive, and if you buy hardware, it can range from 500 to a few thousand.

It is likely that the motherboard is burned out, or because the backlight is off, it may be because the bolt is loose, or it may be because the hardware is in poor contact, if the problem is more serious, the cost of maintenance is about 200 yuan to 500 yuan.

It could be a problem with the power supply, a problem with the internal chip, a problem with the circuitry, or a faulty TV. The cost of repairs is about 300 yuan to 500 yuan.

Generally, because the display is broken, or the circuit is burned, so the display is black, and if you want to repair it, it may cost 300 to 500 yuan.
