White rings on tv screen

Samsung should be liable as it is a manufacturing fault the glue they use to stick on the lenses is sub standard and the TVs should be recalled I have the same problem Samsung don’t want to know never buy any Samsung product again

All answers are correct, but let try to clearify. There are rows of LED (light emitting diode) lights that emit the light for the screen, and on top of those are glued the reflectors, which broadcasts the light created by the LEDs. There is a white defuser panel that covers the reflectors, which evenly defuses, the light created by the LEDs. The LCD (liquid crystal display) sets on top of the white duffuser panel where the light passes through the LCD creating the picture for the screen. When the reflectors fall off the LED lights, the bright light from the LEDs appear as a white rings or spots on the screen. You have two options if the screen is not under warranty, pay to have it repaired, or do it youself. There are videos on the internet that show you how to do the repair, but keep in mind if doing it yourself, it can be a very tedious, and delicate process, especially with larger screens. It is not always as easy as it appears in the videos; one little mistake, and your out of a tv!

I replaced the LED’s in a friends TV and after he got it, it had the white circles. None of the lens had come off, but I did notice there the lens had glue from the tape on them, once I cleaned them all off with IPA the white circles went away.

"Can you post a picture of these ""rings"" please?

As far as I know there are no caps behind the panel. There should be LED strips that provide the back light. These LEDs can fail, but when that happens, usually the entire strip or sometimes the entire back light will fail. Depending on how the strips are powered, the LEDs on the strip are connected in series which means that if one fails, the entire strip will be effected. Some sets power each strip while others have all strips in series. From your description, it sounds like one LED (or 5 if there are 5 ""rings"") is brighter than the rest. This may indicate an LED that is starting to fail.

A picture will help. In any case, either replacing the strip or the individual LED may resolve the problem.

The led light reflector at the back of the led panel has dropped off. Need to call tech to disassemble the panel and to fix it back which normally by using glue
