COMMON LCD TV MALFUNCTIONS AND FAULTS:

The latest Televisions and LCD TV are adding more features than ever before - these new features complicate both electronics and software to help your television run smoothly.

There are many types of LCD TV faults, some of the software and some of them hardware faults.

In the following, we will know the complete details about all kinds of LED and LCD TV faults and problems and provide complete guidance on how to fix them.

TV'S ACCIDENTAL DISCONNECTION:

This could be due to poor power supply or incomplete software or firmware update.

To fix this problem it is recommended that you reset the television to factory defaults and then update or reset the installed firmware/software by visiting the manufacturer's website or updating the OTA on your device.

If you try, you will be able to fix this problem.

TV AUDIO, BUT NOT VIDEO:

This could be due to poor lighting or a faulty board. In the case of faulty LED taillights, you can buy a relatively inexpensive LED controller, although usually if all the taillights are off, this indicates a different problem. If this is a problem with the T-Con board, keep reading below.

T-Con board malfunction: The failure of the T-Con board is indicated by the following symptoms.

1. Lines on the screen.
2. It looks like the TV is on.
3. The sound on the TV is still working.
4. The image is inverted or the colors are shown inverted.
5. TV functions work in addition to screen, sound, channel change, etc.

LCD TV POWER ISSUES:

Badly leaking capacitor, There are many problems with televisions, one of which is that turning the television on and off for a few seconds is usually related to the problem of capacitors on the power board.

If you're having trouble accidentally turning off your TV, or not turning it on at all, the best place to fix it is the power board.

First, take off the back of the TV, and look for the power board. This will be the board where the power cable coming from outside will be connected.

Be very careful when touching them, as current may still be present in the capacitors onboard.

Check all the capacitors carefully, they must be perfectly flat on top and no liquid should come out of them. If any of these are leaking or leaking, they will need to be replaced immediately.

To find fault in capacitors you will need a meter to check which capacitors have higher resistance. This is also important because some capacitors can malfunction without leaking or leaking.

If you know about capacitors you can change capacitors - keeping in mind that the scope for change must be the same.

LCD TV BACKLIGHT PROBLEMS:

Lots of people watch television with backlight problems. One of the reasons is that people and manufacturers like to run the television with 100% backlight.

This is why it often causes LEDs to fail with LED Backlight TVs before the warranty period.

BLACK SPOTS ON THE LCD TV SCREEN:

If there are any dark or black spots on the LCD screen, it is a sign that one or more of the LEDs on the backlight strips have gone bad, causing these spots to appear.

Or if you see a whole line on your screen looking darker than the rest, to repair it, you will first need to buy new strips. When you buy the strips, you have to open the TV back cover and carefully remove the LCD screen from the television set.

f you specialize in decoupling and re-soldering electronic components and necessary equipment, you can do this easily. The best advice is to get it fixed by a TV mechanic.

WHITE SPOTS ON THE LCD TV SCREEN:

If there are white or very bright spots on the LCD screen.

This indicates that one or more of the lenses attached to the LEDs in your TV set have either fallen out or they have moved out of place.

To fix this problem, you can open the TV set and re-stick the lens with the LED. Keeping in mind that this is a very delicate process of queuing the lens, I would suggest that you buy replacement strips and replace the full strips as the new strips come with the pre-attached lenses.

NO LIGHT ON THE LCD TV SCREEN:

There is no light on the screen. This problem depends on the type of television set. This can be the result of any hardship or difficulty.

In general, the following reasons can be the cause. The capacitors on the television power board can sometimes fail and there are no visual signs.

After verifying that the power board is working properly, the next thought will be to the LED strips, visual inspection to see the damaged LEDs may indicate where the problem is available at.

Use of faulty LEDs on backlight strips
Bad power supply board
No power supply is being sent to the LCD TV backlights
Defective LED driver board

BROKEN SCREEN ON TV:

This is one of the most common problems we face and unfortunately, the cost of changing the screen is very high, in almost all cases it is cheaper to buy a new kit which usually has all the latest features and software.

Broken screens are the most common problem and the most common cause is the device's power supply or board. If you manage to unlock the back of your device, take a look at the Power Issues page.

This can often be the result of faulty capacitors on the power supply board.

TV VIDEO DOES NOT MATCH AUDIO:

It is very disturbing when we see someone's face moving but what you are hearing and seeing is inconsistent.

It's like watching a movie or drama with a voiceover. We can solve this problem very easily, for that go to the audio settings of the TV and then adjust the audio delay or setting it to zero. This process will help you to get back in sync.

THE IMAGE IS PIXELATING OR BREAKING:

Weak signals may be one of the main reasons why a television picture is breaking or tearing in and out.

To identify this, check all connections to the cable box or antenna to make sure no connection is broken. If all connections are OK and the TV image is still missing, you will need to contact the cable provider. And let him know your problem so he can help you fix it.

DISTORTED IMAGES:

There can be many reasons for distorted images but the most notable reason may be poor cable quality or TV circuit.

Also, changing the brightness and contrast of the image can give better results.

NOT CONNECTED TO THE INTERNET/WIFI:

You have smart features on TV to connect to the Internet through WiFi or an internet Line. Through this, we can streamline favorite movies, dramas, and programs directly on television.

If the Internet connection is changed, this feature does not work often, check the router or data cable that is set up with the TV.

If an app is not working properly, uninstall this application and re-install it to solve this problem. If there is no work, try TV setting restore your problem will be fixed.

LED TV BLUE/GREEN SCREEN:

When TV shows blue, green, or black screens, it shows that our TV signal is failing to get.

These reasons include input source and cable so make sure the TV is located on the correct input source.

If there is already the correct input source, the connection must be checked. An incredible cable or satellite misleading can be caused by it. The blue screen on the TV only looks when the signal is feeble or the signal does not match with the input source.

TV SETTINGS ARE IMPERFECT OR FAULTY:

Oftentimes small children accidentally remote fall or the buttons are broken but the cause of TV settings is eliminated.

But you do not know about it completely. To fix this problem, the fastest way can be to re-setting/reset factory settings. It can be different from all TV models and companies. On our website, you will easily find ways to settle all TV factory reset methods or you will have to see the manufacturer's website.

But generally, pressure from a special set of specific buttons and codes on the remote control.

FREEZE SATELLITE RECEIVER OR CABLE:

Whether it's a satellite receiver or a cable, it works like a simple computer, and like a computer, it crashes.

To fix it, first, try to turn it off immediately and unplug it with electricity. Wait at least 30 to 40 seconds then turn it on again. This process will reboot the device. To avoid crashes, be sure to not cover the receiver's heat vent, as this is often due to overheating in the receiver.

So if you want to avoid this problem, cool the receiver with a fan and heat shrink used in a hot place for cooling.

TV SCREEN GRANULAR:

This is more common on newer TVs than on older TVs. This means that the TV resolution setting is too high for the content we are receiving.

Some experts even recommend focusing on sharpness, as it can exacerbate any issues with the image source.

TV DOES NOT DISPLAY 4K AND 8K RESOLUTIONS:

Let me tell you - there are two issues here. First, if your new 4K or 8k TV looks too bright, and colorful and the details look blurry, the store uses it in vivid mode.

You will need to switch it to normal, cinema, or movie mode. The second problem is that there must be HDMI 2.0 between the receiver and the television.

Due to these problems, the TV is unable to display high resolutions.

TV IMAGE IS STRETCHED/SQUASHED:

This problem may be caused by an error in the television image format or size.

This includes image zoom, image size, and image aspect ratio. The best size is to keep it on-screen fit, the TV always shows only the video it receives from the receiver. When it comes to older models, you might want to set the video to a 4:3aspect ratio.

Otherwise, if you have a new model TV then it will be kept in a modern 16: 9 ratio. Newer televisions also have this feature and can be easily adjusted with the TV's remote control. We recommend that you keep the screen size to fit.

The remote control has a button called Display or Picture, which lets you easily adjust the TV to the setting of your choice.

HOW TO RESET THE V-CHIP ON TV:

TV turned on, press the (VOLUME-) key on the TV keys panel. Press the 7 number key on the TV remote control to reset the customer ID or PIN code.

To eliminate this problem, press the Home button on the remote and the TV menu screen appears. Adjust color, brightness, and contrast to this menu, or fix it in automatic mode. If you are unaware of this process then resetting/restoring the LCD TV can also fix this problem.

TV screens often become dim or blurred, which can be due to the remote control pushing the buttons in a certain order. Turn on the TV again to see if the issue is resolved. If the problem persists, turn off the TV and unplug the power cord for five minutes, and do not turn it on.

Reinstall the power cord after five to ten minutes and now turn on the TV to check the status of the TV.

If the screen gives a better display then your problem is solved. If the problem persists, please check that the television is connected to an internet connection, so that the software can be updated if it needs to be updated.

If the image on the screen is still blurred, you will need to take it to a TV repair specialist.

TV UNUSUAL DISPLAY:

A very dark scene about a hero in a drama or movie will look like an extraordinary display on the screen in a white shadow form. Reducing the level of backlight will be able to fix this problem.

Go to settings and adjust the image settings using the menu. Adjust light sensor settings in your television setup menu according to your requirement.

In this problem, when the television display is seen, a low light scene is seen, due to the brightness of the lightweight, the scene does not show properly, due to which this problem is called an unusual display.

The powered switch does not exist in some TV models, but you can estimate the loss of extraordinary sound.

This model is necessary to repair TV from television experienced person.

THE TV SCREEN IS EMPTY/BLANK:

In the case of this case, the power supply unit within the TV does not work properly. The unit of power supply is responsible for sending power to all the components of LCD TV, it is generated in the recovery and ahead of electricity.

If the power supply unit is suddenly increased or reduced in the quantity of the power supply, this problem will be displayed. Being this, the capacitor on the board fails to power off.

This set will be opened if the TV is set to open this edge and the leak or billing capacitor is changed.

These problems are more preferred in modern television and this repair work is very easy. Any TV specialist can be served that will change the bad capacitors.

To fix this, turn off the TV and disconnect the power plug. Hold down the power button on the TV for 20 seconds to complete the power cycle. Be sure to wait, ten to fifteen minutes before turning on the LCD TV.

If there is a temporary interruption in the TV, doing so will fix it. Even if these measures do not solve the problem, the bulbs and backlights inside the TV have gone bad.

Because the TV light is about to go out, the first sign is that the light starts to flicker.

The solution would be to have the television checked by a professional.

HALF OF THE TV SCREEN TURNS BROWN:

If half the screen of the television changes color, turn off the TV first and check all input devices. Connect the TV to any media device i.e. DVD etc. If there is a temporary interruption, it will be fine to do so.
