Test The HDMI Cable

To test the HDMI cable:

  1. Press the Home button on your remote.
  2. Go to Settings> Support> Self Diagnosis.
  3. Select Signal Information. 
  4. Choose HDMI Cable Test and start it. 

Test Different External Devices

You should test other external sources to determine whether they cause the black screen issue. First, check if another external device works with your TV. For instance, using a Roku player instead of your cable box may solve the black screen issue. 

If your TV screen starts working fine after connecting to another external device, then your TV wasn’t the reason. If that’s the case, you must replace or repair the external device. 

Check The Antenna Of the TV

A black screen can happen when your TV isn’t receiving strong enough signals. That’s why you must ensure the antenna or the satellite dish is correctly installed and pointed in the right direction towards the sky. Otherwise, the connection may get disrupted, resulting in weak signals. 

Reset The TV

After trying all the methods, if your Samsung TV screen remains black, you should perform a factory reset on your TV. This will restore all your TV settings to the factory defaults. To reset your Samsung Series 5 TV, follow these steps:

  1. Press the Menu button on your TV remote control.
  2. Go to Settings.
  3. Select Support> Self Diagnosis> Reset.
  4. Enter the PIN (default PIN is 0000) when prompted. 
  5. Click on OK to continue and follow the instructions to finish the reset.

Samsung 46 LED TV Not Turning On

If your Samsung 46-inch LED TV is not turning on, there can be several reasons behind it. First, you should determine whether the issue is with the remote batteries, the cable, the power outlet, or the TV itself. 

Replace The Remote Batteries

Sometimes your TV won’t turn on because the remote batteries are dead. First, try turning on the TV with your remote to check if you have dead or weak batteries. If the TV turns on fine without the remote control, you need to replace the batteries with new ones. 

Power Recycling on Samsung TV

Doing power cycling on your TV is similar to doing a soft reset. To do this, keep your TV unplugged for about 30 seconds. After that, plug the TV directly into the power outlet. Turn it on to see if it’s working now. Also, make sure the cables and cords are tightly and correctly inserted. And plug the TV into another power outlet if the former one doesn’t work.

Check The Surge Protector

When using surge protectors with your TV, you need to check them for damage or defect. With time and use, surge protectors wear out and can’t provide enough voltage for your TV. If you have worn-out surge protectors, you need to replace them immediately. 

Samsung 46-Inch TV Keeps Restarting

Usually, this issue is caused by a faulty main board. You should contact Samsung customer service or your local electrician to fix this. 

Fix The Damaged Main Board

It’s better to replace a damaged main board than try to fix it yourself, especially if you’re not skilled enough. Instead, you should get it checked by a professional or take it to a service center. 

Fix A Faulty Sensor

If your TV has a faulty sensor, it may cause the TV to keep restarting. To check that, place a small piece of electrical tape over the sensor and see if it stops the TV from constantly restarting. 

Fix Overheating Samsung Chip

At the back of the Samsung TV, there’s a chip attached to it that prevents overheating the TV. Overheating can lead to the TV randomly restarting. To know whether the TV is overheated, you can touch the area close to the HDMI ports. To fix the overheating problem, open the back panel near the ports to check if the heating chip is displaced. Put the chip back in its place if needed. 

Disconnect the Cable Box of the Samsung TV

If your cable box is causing the restarting issue, you better disconnect and reset it. To do this:

  1. Disconnect your cable box from your TV.
  2. Turn on the TV.
  3. Do a factory reset.
  4. Reconnect the cable box to the TV.

Check Any Damaged or Loose Cables

Also, check all the power and external cables to see whether they fit correctly and snuggly. If you have frayed or damaged cables, replace them with new ones. 

Update The Firmware on Samsung TV

Updating the firmware will eliminate most bugs or glitches in your TV. To do that: 

  1. Press the Home button on your remote control.
  2. Open Settings.
  3. Select Support> Software Update> Update Now.
  4. The TV will check for updates and download the latest one. 
  5. The TV will restart after installing the update. 

Samsung 46 Inch LED With No Sound

If you can’t hear any sound from your Samsung LED TV, check your volume settings first. See if you accidentally put it on mute mode or if the volume is set to zero. If there’s no problem with the TV volume, check the external sources next. 

Check The External Sources

Faulty or defective cables cause audio failure, so check the cable connections for any damage. Also, check the connections for external devices like gaming consoles or PCs. 

You can use a speaker or a soundbar to avoid the sound issue with your TV. You’ll get a significantly better and louder sound quality. Plus, ensure the HDMI ports and settings have the correct audio output. And keep them clean and clear of dirt and debris.  

Run A Sound Test

Running a sound test will help you determine the cause of your TV sound issue. To do that:

  1. Press the Menu or Home button on the remote.
  2. Next, select Device Care> Self Diagnosis.
  3. Select Start Sound Test.
  4. If you hear any problem, select Yes; otherwise, select No.

In the sound test, a melody will be played to determine if there’s an issue with the TV speaker. If you can hear it fine, the problem lies with the connected external device, not the TV itself.

No Bluetooth/ Speakers Connected

If you use a Bluetooth-connected device with your TV, you should also consider that. But first, check if your TV is paired with a Bluetooth headset or speaker. If it is, go to the Audio settings to unpair it or turn the device off completely. 

Samsung 46 LED TV Screen with Dots and Lines

Sometimes, white spots or colored lines appear on the screen, which makes it difficult to watch TV. When this happens, you should consider running a picture test first to determine the issue.

  2. Select Support.
  3. Select Device Care> Self Diagnosis.
  4. Select Start Picture Test. 
  5. Select OK to advance. 
  6. Test pictures will appear.
  7. Follow the on-screen instructions to complete the test. 

If you see lines and dots on the screen during the picture test, it can be because of a cracked screen. You have to replace or repair the screen in that case. However, if you don’t see any lines or dots appearing during the test, in that case, the issue may be with the external device connections. 

Check Connection with External Device

Bad HDMI connections can mean faulty HDMI ports and cables or loose HDMI connections. To ensure the connection with the external device is working, check if the cables are correctly plugged in. Also, disconnect all external connections from the TV and reconnect them. You can also try using a different HDMI port and/or cable when disconnecting and reconnecting don’t work. 

Replace Fallen Reflector Inside the Panel

Another reason for lines or spots appearing on Samsung TVs is caused by fallen reflectors inside the panel. Typically, reflectors are situated in front of the LED backlight for spreading light on the screen. However, the plastic reflectors tend to fall off if the TV gets overheated.

To replace the fallen reflector, you’ll have to open the back panel of the TV first. Then, find the fallen reflector and glue it back to its place. If there’s too much damage to the reflector, you must replace it.
