However, before engaging in the repair process, ensure you wear footwear and safety gloves and follow the instructions to rid your Samsung TV bright spot.

If a loose reflector is the cause of your TV’s bright spot, you need to open the TV and glue the reflector back to its normal position.
In addition, get items such as glue, gloves, toothpick, prying tools, screwdrivers, and other tools you need.
#2. Disconnect Your TV From Power
After getting all you need for the repair, disconnect your TV from the power source. It is important to prevent electric shock when working on it.
Wait 15 minutes to ensure there’s no power in the capacitor, and you won’t have a problem with the residual power in the TV.
#3. Place Your TV on a Flat Surface
Ensure you place a soft material like a quilt on a table that’s large enough for your TV and place it on it.
The soft material you place on a table protects your TV screen from damage. So it’s important to place your tv on a soft surface.
You do not necessarily need to place your TV on a table if you don’t have a table big enough for your TV. You can use your mattress instead of that.
#4. Unscrew all the Screws Behind the TV
Check for screws behind your TV, and use a screwdriver to remove all the screws you find. A screwdriver magnetizer and demagnetizer would be useful here if you have them.
While unscrewing the screw behind the TV, it would help to have a screwdriver magnetizer and demagnetizer so you can use the magnetizer part to draw and stick the screws to it.
You need to note where each screw is on the TV so that when it’s time to replace it, you’ll be able to do that without stress.
#5. Remove Your TV Cover
After loosening all the screws behind the TV, remove the back. You can also use a small prying tool alongside your fingers to lift the edges and make it easier to remove the TV cover.
#6. Remove the Screen
After removing the cover, turn over your TV with the screen facing upwards. Take off all the screws that hold your TV together, if present.
Remove the TV frame; you can use a prying tool to help with it. Next, remove the cable holding the screen to get it out.
#7. Remove Your TV Diffuser Panel
The white part you see is your TV’s diffuser panel. It’s the one that spreads out the light coming from your TV reflectors.
Before removing your diffuser panel, detach the bezel connected to it and label the sides of the reflector. It is for you to know the correct position of the reflector.
It would be best if you labeled the sides of the reflector so you can place the diffuser correctly when reassembling it.
#8. Glue Back Your Reflector
Under the diffuser panel is the reflector. The reflector consists of clear lenses spread evenly on your TV. Next, you need to glue back the loose reflectors in the TV.
Apart from gluing back the loose reflectors, ensure you check on all the other reflectors to see if they’re tight to avoid closing the TV and still having the problem of loose reflectors.
Here’s how you can glue back the loose reflectors on your TV;
- There is 3 post-holes guide reflector positioning around each TV LED, and each reflector lens has 3 LED posts. Ensure the lens posts fit LED holes so they won’t fall off.
- Add superglue to a piece of paper. Do not add excess glue.
- Use a toothpick to add superglue to the postholes of the LED light.
- Put your reflector on top of the post-holes you have glued down.
- Use the toothpick to apply super glue to every LED light with a loose reflector.
#9. Replace the Diffuser Panel
You labeled the diffuser earlier, which makes replacing it easier. Next, insert diffuser tabs into TV hooks and press the diffuser’s edges to lock into place.
#10. Replace Your Screen and Cover the TV
Replace the TV screen and the frame of your TV and position them correctly to lock them in place. Screw back all the screws to the back of the TV.
Finally, return your TV to its position and connect it to a power supply. Then, put it on to check if the bright spot isn’t there anymore.
