This is a 55" LG Edge-lit led Television model 55uf6450-ua which powers on but the screen flickers on and off constantly. We definitely have an Led light or Back light problem. In this video I'm going to show you how to take this TV apart and Change the led strips, thus repairing the flashing screen on this television.

I don't know what is up with my LG. It blinks off and on but not always. I won't call it flickering. So I turn it off, only to find out it doesn't turn off. I hear audio but not video. So I turn it back on, only to see it blinking. I use it as monitor to my desktop computer. This has been happening for the last couple of months. It did it while I was watching your video and didn't let go of the attitude. Right now it is working fine. It works good for days and then from nowhere comes the attitude. 🙂

He's good but needs rubber gloves as the oils from your hands leaves so many marks when the TV is on they illuminate as it's in the textured matt layer and let's the light straight through and had to clean off with glass wipes as anything that leaves streaks or marks can show giving a cloudy affect noticeable when looking at anything other than a still image

Luck what I discovered: My fire stick 4k (3 year old) was the item that was causing the screen problem. I noticed that after I connected my brand new fire stick 4K Max, after a minute the screen get very bad with different pixel lines..... I was using Netflix.... then I opened Netflix on the tv app and it was working all normal. also I used the cable box and all was running good. Also I plug this fire stick to a older SONY tv and the device working all normal. I speak with LG about this problem... and then could't help me. No even to give a discount to buy a new tv. Now I have to throw away my tv and buy a new one. SO I end with LG. NO MORE LG BRAND FOR ME.
