don’t junk it just yet. It is entirely possible that this is a power board issue. Remove the back of your Tv and take a look at all the boards. check for obviously damaged components like leaking or domed looking capacitors etc. Post some images of your boards etc. with your question so that we can see what you see. Use this guide [guide|21499] for that. You can of course also check the power board output to the LED’ backlight with a multimeter.
