Troubleshooting for your Samsung LED TV Series 45: let’s get started

Steps To Fix The Lines, Spots, And Dots On Screen

Consider doing a picture test when lines, dots, or spots appear on the TV screen. To do a picture test:

  1. Go to Settings.

  4. Choose Start Picture Test. 

You’ll see a series of pictures during the test. Select Yes or No to answer the on-screen questions and follow the instructions to finish the test. If lines or dots appear during the picture test, it can be because of a cracked screen. You’ll have to replace or repair your screen in that case. However, if you don’t see any lines or spots on the screen during the test, there may be issues with the external device’s connection or signal strength. 

Test The HDMI Cable To Fix the Black Screen 

A black screen on your TV happens when you have a damaged or defective HDMI cable. To check if the HDMI cable is broken, you can run an HDMI Cable Test. First, ensure the TV source is set on the HDMI setting for the cable you’ll be testing. 

To do an HDMI Cable Test:

  1. Go to Settings.
  2. Select Support> Self Diagnosis> Signal Information.
  3. Choose HDMI Cable Test.
  4. Click on Start Test. 

Replace the cable if the test shows it to be defective.

Update The Firmware To Fix Blurry Images

  1. Press the Home button.
  2. Go to Settings.

  2. Go to Picture.
  3. Choose Picture Mode.
  4. Click on Natural. 

Reset The Cable/ Set Top Box If Picture Is Freezing

Sometimes, service providers push a software update in the modem or the cable box, which causes reception issues. A soft reset on the cable box or the set-top box will resolve the freezing picture issue by resetting the hardware. 

First, unplug the modem or the cable box from the power outlet. Then wait for about 10 to 15 seconds. Next, plug it back into the outlet. Finally, turn on the TV and check if the picture is restored. 

Troubleshoot The Samsung TV Series 45 That Is Not Turning On

You can try several fixes when your Samsung TV doesn’t turn on.

Samsung LED TV Series 45 Troubleshooting – A Complete Guide

Replace the TV remote batteries

The dead remote batteries are the most straightforward reason for the TV not turning on. So first, check if you got weak or dead batteries on your remote. If you can’t turn it on with a remote but can turn on the TV manually without the remote, then you need to replace the batteries. 

Power Recycling Of Samsung TV

Power recycling your TV is similar to doing a soft reset. To do it, keep your TV unplugged for about 30 seconds. After, plug the TV directly into the power outlet. Finally, turn the TV on and see if it works now. 

Fix The Original Outlet Problem

A faulty or damaged power outlet won’t provide sufficient power to the TV, and thus it won’t turn on. To check if your power outlet is damaged, plug your TV into another power outlet. If the new one works, the original power outlet was at fault. Also, make sure all the cables are plugged in firmly. 

Check The Surge Protectors

Check the surge protectors for damage or defect when using them with your TV. Surge protectors wear out with time and use and can’t provide enough voltage for the TV. So, if you have worn-out surge protectors, replace them immediately.

Samsung TV Series 45 Apps Not Working

You can try some quick and easy solutions if the apps are not working on your Smart TV. 

Cold Reboot Of Samsung TV

You can try cold boot your TV in two different ways: 

  • With a remote: Press and hold down the Power button on the remote control until the TV turns off and power it on again. 
  • Without a remote: Unplug the TV from the power outlet. Wait for about 30 seconds, and then plug the TV back on. 

Once your TV completes restarting, try opening the app again to see if it’s working. 

Update The Firmware And App

Usually, there will be a pop-up on the screen to notify you about updates. However, if the apps freeze before updating, you won’t be able to see anything. Therefore, you need to go to the Samsung App Store and update the app from there. 

Also, apps can only work if you have updated firmware. You must update your TV firmware; if you still need to, you should update it manually. 

  1. Go to Settings. 
  2. Select Support> Software Update> Update Now.
  3. After checking for updates, your TV will download the latest one.
  4. Once the update installation is done, the TV will restart.

Check the Internet Connection

For streaming apps like Netflix, YouTube, Hulu, etc., a Bad LAN connection or poor wireless connection will hinder the streaming. In that case, you should troubleshoot the router or install an expansion router to get a stronger connection.

Samsung TV Is Not Connected To Bluetooth/ Speakers

Check if you’re using any Bluetooth-connected device with your TV. Because when your TV is paired with a Bluetooth headset or speaker, the sound will come out of the Bluetooth device instead of your TV. So if your TV is paired up, make sure to unpair it through the Audio settings or turn off the Bluetooth-compatible device completely. 

Samsung TV Is Not Muted

Sometimes, accidentally, we end up muting the TV; thus, no sound comes out. So check and make sure you haven’t unknowingly put your TV on mute mode. Even if you do, just unmute it, and the sound will be fine. 

Cold Rebooting Of Samsung TV

A cold reboot is similar to a soft reset on your TV. There are two ways you can do it:

  • With a remote: Press and hold down the Power button on the remote control until the TV turns off and power it on again. 
  • Without a remote: Unplug the TV from the power outlet. Wait for about 30 seconds, and then plug the TV back on. 

Samsung TV Series 45 Not Connected To the Internet

If your TV is having trouble trying to connect to the internet, here are a couple of steps you can try to fix the wireless connection. 

Steps To Fix The Connection With Wi-Fi

  • Check external devices: If too many devices are connected to the network, try disconnecting one. Then, when the network isn’t crowded anymore, the TV will connect automatically. 
  • Reboot the Wi-Fi router and the TV: Rebooting them will remove any bugs or glitches causing the connection issue. 
  • Call Samsung customer service: If the network issue persists, you should contact Samsung customer support and ask for guidance. 

Samsung Smart Hub Does Not Display Any Apps

If your Samsung Smart Hub doesn’t display any apps, doing a hard reset can help fix it. 

Restore Factory Settings

To restore the TV settings to the factory defaults:

  1. Press the Menu button.
  2. Go to Settings. 
  3. Select Support> Self Diagnosis>Reset.
  4. Enter default PIN 0000.
  5. Select OK and follow the on-screen instructions to finish the reset. 

Switching TV Back To the Original Settings

To switch your Samsung TV back to its original settings:

  1. Press the Smart Hub or Home button on the remote.
  2. Next, press the following buttons: fast forward, 2, 8, 9, and rewind.
  3. Select another location in Setup.
  4. Accept the Terms and Conditions.
  5. The Smart Hub will be updated and reset. 
  6. Repeat the steps and switch back to your original location. 

Samsung TV Series 45 Sound Quality Problem

If you experience distorted sound coming from the TV, you should perform a sound test first. 

Perform The Sound Test 

You can run a sound test to check the sound quality of your TV. 

  1. Press the Home button on the remote.
  2. Go to Settings> Support. 
  3. Select Device Care> Self Diagnosis.
  4. Select Start Sound Test.

During the sound test, a melody will be played to determine if there’s any problem with the TV speaker. If you can hear the sound normally, the problem lies with the connected external device, not the TV itself.

Check The Signal Strength And Cable Connection To Fix Noise From  Speakers

Due to bad weather, you’ll get weak signal strength, resulting in poor sound quality. Broken or faulty cables are also responsible for distorted sound from your TV. You can check your TV’s signal strength by following these steps:

  1. First, press the Menu button on the remote. 
  2. Go to Settings.
  3. Select Support> Self Diagnosis.
  4. Select Signal Information. 

The Signal Noise Ratio (SNR) has to be greater than 20db for it to be the optimum signal. So for clear audio, you must ensure greater signal strength for your TV.  

Troubleshoot Half Screen Display On Samsung TV

When half of your Samsung TV shows a black screen, either from the right and left or from the top and bottom, you should go for TV servicing. 

Go to the Menu section to find out whether servicing is needed. If you can see the section on the TV screen perfectly, the issue is caused by cables and external devices. And your TV won’t require servicing. 

Fix The Panel Or Main Board

Usually, a half-screen display on TV occurs due to poor broadcasting signals or issues with the main board or panel. Doing a repair or replacement will fix the half-screen problem in no time. And however, you should seek professional help or contact Samsung customer service for guidance. 

Check The External Device Connection

To ensure the external device connection is working, check the cables first. See if they’re compatible, firmly connected, and in pristine working condition. If you have damaged or defective cables, replace them immediately. 

Turn Off The External Devices And Back On

You can power cycle the external devices and check if the black half-screen goes away. To do a power cycle, press and hold down the Power button on the device until it turns off and then turns on again.  

Whether you’re experiencing issues with your TV’s picture or sound quality, knowing how to troubleshoot the problem always helps. Sometimes, you may find your Samsung TV turns off randomly or the apps stop working. You can fix any of these problems with our Samsung LED TV Series 45 troubleshooting guide.


Why Does My TV Shut Off After A Few Seconds?

A loose connection is the most probable cause for your TV to shut off unexpectedly. So first, check the external devices connected to the TV, like a set-top box, game console, PC, etc., and see if the connection is working. Also, you should check for damaged or frayed cables and replace them if there are any. Besides, a faulty remote can trigger the TV to turn off, so take out the remote batteries to replace them. 

How Do I Repair My TV Screen?

All Samsung TVs have a warranty, so contact Samsung Support Center to repair your cracked screen. You can send it through the mail or set up an appointment for the authorized Samsung technician to visit and repair it directly at your location. However, your TV has to be 32 inches or smaller to qualify for the mail-in repair service. 

How Much Does It Cost To Repair An LED TV Screen?

The screen is the most expensive component of the TV and the most susceptible to damage. As a result, repairing a screen sometimes gets more expensive than buying a brand-new TV. Usually, a TV screen repair costs around $200-$400, but the cost can go up to $1000.

Is It Possible To Operate A TV Without Using The Remote Control?

Yes, it’s possible to operate the TV without the remote control. All Samsung TVs have a control button that lets you turn the TV on and off and change the source input and the volume. You can also access the Menu, Settings, and Smart Hub. However, without a remote, your TV will have limited functionalities.

How Do I Get A Universal Remote To Work On My TV?

Universal remotes are like normal remote controls but can be paired up with multiple devices, even from different manufacturers. With one universal remote, you can operate multiple other devices. For the universal remote to work on your Samsung TV, you’ll have to pair them using a code. 

First, turn on your TV and hold the universal remote in the TV’s direction. Next, press the PROG button and keep holding it until the LED light on the remote shows up. Next, press the INFO button. Next, press the button and enter the code from the user’s manual. If the code is correct, you’ll see Success on the screen, and if it isn’t. Repeat the process with another code if the first attempt is unsuccessful. The power button will light up when your Samsung TV is connected to the universal remote. 

Why Does My TV Shut Off After A Few Seconds?

Your TV can shut down unexpectedly due to a loose connection or an aged power supply cord. To avoid further issues and potential electrical hazards, it’s time to shop for a new TV if your power cord has frayed or damaged.
