@hadirawal no image attached to your question. Use this guide Ajout d'images à une question existante to add pictures to your QUESTION.

From what you are describing it does sound like some of the diffuser caps have come off the LED’s. A lot of times you can glue them back on. Of course we will have to see what it looks like to verify this.

2nd picture is hard to identify with my old eyes. Is that a shadow or is it dented? If it is dented you will have to replace it.

@hadirawal you will have to replace that. The crease will always show up and change the distant and reflection of the backlight LED's

Please see the attached photos

Leds are making circles around, is this wrong?

@hadirawal that is correct. I am a bit confused by what you are asking. The crease in the paper changes the distance from the LED's to the diffuser sheets. The diffuser sheets are what makes the light uniform and even, instead of showing the circles.
