Thank you brother Oloo, for the branded television(Sony, Samsung, LG, Toshiba etc they start failing from around 5years from experience, But for Cheap China made like, Vitron, Hisense, mooka, skyview etc begin failing in less than two years, that is why in Kenya if you don't know how to replace backlight you are missing a lot. harvest is plenty and laborer(techs) are few, you can take that to the back.

Good question Yogesh, not really because I usually replace back the reflectors back after replacing the bead.

Good Repair!
In last photograph white bright patches are seen on the screen display.
is that because of Missing LED Reflectors ??
