Do you have a flatscreen TV at home? You’ve probably encountered vexing issues and wish to discover a long-term solution. In case this matches your scenario, below are 6 of the most typical difficulties detected by a tv repair shop with flatscreen televisions.

The LED TV screen goes black.

There may be times when you switch on the television, and nothing happens. If there are no signal difficulties with the devices connected to your TV, you are most likely dealing with a power supply outage inside the TV.


  • Power surges that affect your TV and destroy components such as capacitors are the most common source of power supply issues.
  • This damage is seen when a capacitor bulges or leaks.
  • Only the broken components must be replaced for this solution to be simple. For a technician, this is an easy task. 


If you lack the essential skills, you should leave electrical equipment repairs to a professional tv repair shop.

LED TV only shows a blue, green, or black screen

The screen on your television may periodically flicker blue, green, or black. This problem is typically attributed to the TV’s inability to display a signal.

  • Check that the right input source is chosen on your television.
  • If you’re on the right track, check for any loose links. 
  • A faulty cable is most likely to blame for the problem.
  • If you are watching live TV, the issue is with your cable or satellite subscription. 

Troubleshooting may benefit from collaboration with your provider. Because the free broadcast TV signal is poor, you must modify your antenna.


The image is pixelating or breaking up.

Pixelation may occur on occasion when watching video on your television. A bad signal causes this issue. This difficulty happens when you use a satellite or cable to watch TV because of issues between the broadcast location and the television station. 

Unfortunately, you have no control over the circumstance. Despite your best attempts to minimize sharpness, transmission remains a problem. If this issue occurs when utilizing video streaming services such as Netflix or YouTube, it is most likely due to your TV needing to obtain the optimal Internet speed.

This issue is common when several devices are linked to a single local network and Internet source. Removing these devices from the Internet can reduce congestion and enhance streaming quality. Connectivity issues with your cable or internet provider might cause poor video quality.

TV does not properly display high-resolution content.

If your TV isn’t displaying high-resolution information, look for two items. If the television is spanking new, chances are it is in vivid mode, and the image seems bright and colorful but with indistinct details. Retailers use the bright setting to persuade shoppers to look at their items from a distance. The TV was designed to catch the attention of pedestrians, which is why certain aspects are pixelated or unclear.

It is a simple problem to tackle. If you wish to use the TV for gaming, go to the visual settings and pick Movie/Cinema or Game. The second issue is related to the video source.

If you wish to see something in 4k resolution, your video source must be capable of supporting it. HDMI 2.0 is the bare minimum.

The TV image is out of proportion.

The video may become distorted when you connect to a gadget or watch a movie from an external source on your TV. The resolution settings are the source of this issue. You should adjust the aspect ratio or other necessary settings to make the image perfect.

For old devices, such as DVD players or classic video game consoles, you must convert the movie to 4:3 resolution. If you do not adjust the aspect ratio, the screen will be expanded to the current 16:9 balance. When utilizing the TV as a computer monitor, you must disable overscan to avoid unusual resolutions on the net.

The TV has no sound output.

You switched on the television, but there is no sound? 

Here are some troubleshooting recommendations.

  • After turning off your TV, hold the power button for 10 seconds.
  • After a brief delay, reconnect the TV and turn it on by pushing the power button once.
  • Check for any issues with other sound outputs.
  • Try connecting the TV to various speakers to pinpoint the source of the problem. If there is any sound, the TV’s speakers are broken.
  • If no sound emerges from the external speakers, the fault is likely with the TV’s audio IC chip. A professional LCD tv repairs must change this component.
