hello on the above tv i changed lent normally at the bottom i put the leds look strongly round at the point where they are installed and up to the middle it has very good bright lighting from the middle and up it is a little darker and looks ugly this difference can someone advise me what can be to blame as it was the old ones i placed and the new ones precisely Simply because the plastic through which light is transmitted 7 of the old leds had burned and made a hole in it when I placed the new leds I turned the light transmission plastic and put the top of it at the bottom to be straight with no holes in relation to the new leds
There is a possibility that the above problem is also due to poor quality of the new leds

The dispersing plastic CANNOT BE RETURNED. For correct operation, it must be replaced.

Anytime I switched the edges around it only resulted in the light illuminating the edge where the leds are.

You need to add pictures. Stop asking things without pictures, we can't see what you are asking about

So with Samsung like this, the old LEDs get too hot and they melt the diffuser sheet that spreads the light. Generally a crack or any melting is going to then show up when you reinstall the lights.

It's a combination of the fact that the diffuser sheet wasn't properly put in place or the white bezel wasn't pushed down into place far enough or the bezel was also melted allowing a space between the white bezel and diffuser.

When I fix these Samsungs I have to have a good diffuser off a broken TV and I transplant that over. This is common to occur when repairing Samsung edge lit LEDs and they are junk when needing repair.
