"MVRK RAJU  going by your description alone this sounds like the diffusers are coming of the backlight LED’s. You would have to post some images of what your screen shows with your QUESTION. Adding images to an existing question

If so, you will have to disassemble your panel and either replace the backlight strips or try to glue the diffuser caps back on."
