Hi,
I have seen some threads that touched this subject, but none of them actually answered the question I have in my mind.
I've bought a 'not working' Samsung UE49NU7100K, which turned out to be working but with no backlights. I did not bother to do any PSU measurings as TV itself is working, was pretty sure a single LED has burned out.
After disassembling I was surprised to see edge-lit backlight and the diffuser which was cracked and melted in many, many places, almost like every single LED has burned it. Most of the LEDs look burned out by the way, which made me sure there is no point in replacing single bulbs, rather the whole strips.
My main question is: is the diffuser one-directional? It looks exactly the same thickness at every side, and I'm wondering if there is any point in replacing the LED strips and just twisting the diffuser upside down so the lights are 'touching' the clear, not melted side. If that's not the case, is there any place I can buy a replacement diffuser, or is it possible to DIY one?
Btw will the LED strip come off the heatsink with some help of a sharp blade and/or hot air? There are no screws on them and they look and feel attached pretty solid.
Many thanks for any advices and honestly sorry if that has been already answered.
