Seeing a bright spot on your TV can be super annoying and most of the time impossible to ignore. This issue is more common on the Samsung TV but it can happen to other TVs as well.
Whether you own a Samsung TV or not, if you are seeing a bright spot on your TV there could be a few different reasons that could be causing this issue.
In this guide, I will be going over the different reasons why you are seeing a bright spot on your TV and ways you can troubleshoot the issue yourself.
Why Are There Bright Spots on My TV?
Below I will be going over why you are seeing bright spots on your TV and ways you can solve these issues.
Note, the reasons why you are seeing bright spots on your television screen may be different depending on if you own a LED (Light-emitting diode) or an LCD (Liquid Crystal Display) TV.
If you do not know the difference between a LED or LCD TV; the LED monitors use a light-emitting diode for black lights, while the LCD monitors use fluorescent blacklights. Most people prefer the LED TV because it is more energy efficient and has a better picture quality.
1. Reflectors Are Loose
Seeing bright spots on your TV can be because of a loose reflector, reflectors on your television screen are meant to spread the light in the TV. The reflector inside your television can fall off its designated spot or become loose after some time.
Reflectors can fall off due to being exposed to high heat inside your television or overall poor-quality reflectors. When this happens all the lights will shine at a single point causing a bright spot on your TV.
Fix – Reattach Loose Reflectors
If you are confident in working on your TV yourself there is a way you can reattach the loose reflectors that are causing the bright spot on the screen.
To do this you will have to open up your television, before there are a few things that you will need to fix. Note, you can contact an expert to do the repair for you if you do not feel comfortable doing it yourself.
Tools You Will Need
- Safety Gloves
- Medium Sized Screwdriver
- Small Sized Screwdriver
- Prying tool
How to Reattach Reflectors
- Unplug your TV from the wall socket.
- Wait a few minutes to continue, you want the TV’s capacitors to drain the remaining power, this prevents any electric shock.
- Put your TV screen down on a soft flat surface.
- On the back of the TV remove all the screws. Keep in mind that the screws on your TV will differ in size, keep note of where you removed them from so it is easier to screw them back in.
- After all the screws are removed, remove the back of your TV
- Flip the TV over so the screen is now facing you
- Unscrew the edges of your screen because you are now going to be removing the television screen.
- Use the prying tool to help lift the TV fame.
- Disconnect the cables connected to the screen, after you can now safely remove your television screen. Note, make sure you place the screen on a clean soft flat surface so no damage comes to it.
- The white surface that you see is the diffuser panel, you will need to lift and remove the diffuser panel. Make sure that you mark the sides of the diffuser panel so you can put it back into the right spot. Note, if you replace the diffuser incorrectly your TV will not display correctly.
- Behind the diffuser panel you will now see and have access to the reflectors
- You will want to reglue the reflectors now
- Look for any loose or fallen reflectors, once you found them all you can start gluing them back. Use the Q-tips so you do not apply too much glue, too much glue will cause damage to the reflectors.
- After all the reflectors are glued and secure now you can put everything back together.
- Make sure all the parts are put back correctly, once that is done plug in your TV, turn it on and check to see if the spots are gone.
2. TV Pixels Are Dead
Dead pixels can also be the cause of seeing a bright spot on your TV, this can be annoying. If you tried to fix the reflectors on your TV and you are still seeing bright spots on your screen it could be because of dead pixels.
Having dead pixels may not mean that your TV is permanently damaged, it can however affect your viewing experience. There are a few things you can do to fix your TV if it has dead pixels.
Fix – Let the TV Rest or Use a Computer Software
One of the easiest things you can do to solve the bright spots on your screen if it is due to dead pixels, is to turn your TV screen off. It is best if you wait for 24 hours before turning the TV back on again to see if the spots are still there.
Another thing to do is use a computer software designed to detect dead pixels and help try to repair them. You will need to connect your TV to your computer or notebook via an HDMI cord.
Once connected you can not activate the repair software on your computer/notebook, if the TV’s pixels are still salvageable the repair can turn them back on.
Note, this process may take a few hours to run, be prepared to wait a while. Do not be afraid to look up any YouTube videos for visual aid and more assistance.
3. TV Got Damaged/Hit
Accidents happen all of the time, especially around electronics. This could happen for many reasons, your TV got hit hard by an object, your TV got knocked over, or even bumped into a little too hard.
Whatever the reason is if your TV got damaged this could be why you are seeing bright spots on your screen. This could cause the reflectors of your TV to become loose or even fall off, or it needs to be repaired by an expert.
Fix – Check Reflectors or Call For a Repair
If your TV has been hit and damaged to the point you are seeing bright spots on your television screen it could be because the reflectors became loose due to the hit.
Enough force can cause the reflectors to even fall off from their position. Follow the steps above in the first fix to check the reflectors on your TV.
If you do not notice any loose or fallen reflectors, call an expert to repair the TV for you. If you have a warranty see if you can get your TV replaced altogether.
4. Hot Spot on the Screen
Another cause of seeing bright spots on your screen can be because of hot spots which happen when the screen is overexposed to the blacklight LEDs.
This is due to too much contrast exposed on the television screen, which, in turn, can cause clouding on the screen. There are a few actions that you can take when hot spots accrue.
Fix – Change Backlight Settings
When your screen is exposed to too much of the blacklight LEDs this can cause the bright spots to appear on your screen. Go into your setting and lower the blacklight and turn up the brightness. If this does not work you will need to contact a professional.
5. Faulty TV
When you have checked everything from the pixels, and the blacklight settings, and even opened up your TV to reglue the reflectors, this could be just a faulty TV.
Television screens do deteriorate over time, if you are experiencing this on an older TV then maybe it is time to replace it. If you are experiencing this issue on a new TV then it could be a manufacturer defect due to improper assembly.
Fix – Contact Support/Replace TV
Contacting the support team of your TVs manufacturer may be the best step to go when dealing with a faulty television. The support team will help you troubleshoot the issue and guide you on what to do next.
If you have a warranty this can be a simple replacement especially if the company is at fault for this issue.
However, if your TV is older, consider the cost of a repair and the cost of it getting replaced with a new one. Sometimes it is cheaper overall to get a new TV because there is no guarantee your TV can be fixed.
