  • Unplug and plug in the power plug of the television and the satellite receiver, if any.
  • Check the satellite signal level and quality.
  • Check the cable between the satellite dish and the television. (If there is an attachment, make a connection especially through a single multi-cable.
  • Check the satellite dish. If available, check with a signal meter. Otherwise, make light movements in the bowl. This process is done by two people.
  • Check LBN. (Let the cable entry face the bottom and try moving it depending on the situation)
  • To try it out, find a loaner external satellite receiver and try it.
  • After trying, reset it to factory settings and install again.

Check HDMI Connection

It is important to check the HDMI connections to resolve problems with your television. There are two main points of failure that can cause problems with video and audio transmission: input sockets and cables.

Step 1: Checking HDMI Cables

  1. Disconnect and reconnect the HDMI cable at both ends (the television end and the other connected device end). Repeat this process for each device connected to the TV.
  2. Use a known good HDMI cable and replace it with the cable you think is problematic. Test this change by making this change for each of your resources in turn. If this change solves the problem, consider purchasing and using a new cable.

Step 2: Checking HDMI Input Settings

  1. Check which HDMI source is selected in your TV's settings menu and which HDMI input you are connected to. Although a mismatch between input and settings is unlikely because you're getting sound, check anyway.
  2. If the problem persists, try a different HDMI input. For example, if a device is connected to HDMI1 and it is not working, try connecting it to HDMI2 and try. Your TV can automatically search for the active source.

Step 3: Trying Another Device

  1. If the problematic HDMI port still doesn't work, test if another device is working on that input. If a different device works fine, it indicates that the previous device may be problematic.
  2. If neither device works smoothly, this may mean that the HDMI input is physically damaged or there is a major software problem. In this case, you can consider steps such as Factory Reset.

Note: In some cases, uncertified HDMI cables can cause problems. That's why we recommend using a certified HDMI cable. Additionally, some newer TV models may have an HDMI test mode. Using this mode, you can check possible faults in the cables.

There is Sound on Some Channels on the Satellite but No Image (Satellite Dish Control)

If your satellite dish moves even a millimeter, the image and sound quality will be affected. For this reason, the location of the antenna is very important. It must be installed securely and in a location that will not be affected by winter and windy times. It is important that it does not move.

Software Problems and Factory Settings

You can try the steps below to resolve potential software problems on your television. These steps offer different approaches to get your TV working properly.

Step 1: Checking for Software Updates

  1. If automatic updating is not enabled on your TV or the update is working incorrectly, you may consider performing a manual update.
  2. Wi-Fi-based updates can sometimes be unstable, so you can use a USB port or flash drive as a more reliable update method.

Step 2: Resetting to Factory Settings

  1. If you couldn't fix the update issues or the TV is still not working properly, you may consider factory resetting as a last resort.
  2. However, before taking this step, take note of any special settings and configurations you have made on your TV. Because factory reset will delete all personal settings and data.
  3. Use the instructions on how to reset your TV to factory settings. These instructions can usually be found in the user manual or on the TV manufacturer's official website.
  4. After resetting to factory settings, the TV will have all its settings reset, just like the first installation. If this reset solves your problem, you may need to spend some time reconfiguring your previous settings.

There is Sound on Some Channels on the Satellite but No Image (Hardware Problem)

If you think your TV has hardware problems, you can diagnose these problems through the steps below. Please read the following instructions carefully and remember the safety precautions.

Step 1: Backlight Test

  1. Turn on your TV and make sure you connect it to a working audio and video source. This step will help you verify that the TV is working normally and you can receive images.
  2. Shine a flashlight brightly at the TV screen. Check carefully whether you can see an image on the screen under the light of the flashlight.
  3. If there is an image in the areas where you shine light, this may indicate backlight problems. Considering that other components are working to create the image, it is conceivable that the backlights are damaged. In this case, it may be necessary to replace the backlight.

Step 2: Checking the Power Supply

  1. If you cannot see any image, you should first check the power supply of the TV. Make sure you have connected the power outlet and the TV correctly.
  2. If the power supply is faulty, it may prevent the TV from operating. Check if there is a problem with the outlet or the TV's power input.

Remember that diagnosing hardware problems can sometimes require expertise. If you have difficulty or do not feel confident in following these steps, seeking the help of a professional may be a good option. Also, don't forget to check if your TV is under warranty and if you can get help from the manufacturer's support line.

Cable Controls and Connections

Your television may be experiencing connection problems. You can check the cable connections and try to solve the problem with the following steps:

Step 1: Checking Cable Connections

  1. Make sure the TV's power cord is unplugged.
  2. Disconnect and reconnect each cable one by one.
  3. Pay particular attention to the ribbon cables that run between the small card called the T-Con card and the Main Board.
  4. If there is dirt or dust accumulated on the contacts on the ribbon cables, you may want to gently clean them first.
  5. Be careful when removing and connecting cables. Cable entry directions are generally uniform, but it may be helpful to mark each cable as you disconnect and reconnect it.
  6. Check the LNB. Check cable ends on both sides.

Step 2: Checking the Status of the TV

  1. After checking the connections, plug in the TV's power cord.
  2. Turn on the TV and check if there is an image on the screen.
  3. If the image appears, the problem is solved; but if the problem persists, go to the next step.

If you are unable to resolve connection issues or are having difficulty following these steps, you may consider seeking the help of an expert technician. It is important to be careful when touching hardware components and making connections. If you cannot follow these steps or have reservations, it would be safest to seek professional help.

Defective LCD Panel and Repair Status

If the Bad Backlight test is inconclusive and your TV screen continues to have problems, then your LCD panel may be faulty. Symptoms of a faulty LCD panel can be varied and these are some common signs:

  1. Single horizontal or vertical lines: Horizontal or vertical lines may appear on your screen outside the image.
  2. Broken pixels or areas: Broken images or chromatic aberration may occur in a specific area on the screen.
  3. Defects in a single spot: Defects or color changes that appear only in a specific spot on the screen may also be a sign of panel failure.

In many cases, LCD panel failures can occur as a result of physical damage or abuse. At the same time, due to the structure and design of LCD panels, problems may occur that may be irreparable.

If your LCD panel is defective, the repair cost at this point can often be high. Replacing the LCD panel is a complicated process and also costly. Replacing the panel may not make economic sense. In this case, you can alternatively consider selling the other internal components of the TV.

Please note that replacing the LCD panel should usually be done by professional technicians and may differ depending on your TV model. If your TV is still under warranty or has a technical support line, it may be helpful to get expert advice using these resources.
