I bought LG 43UF6430 4K UHD Smart LED TV 2-3 years back. Due to unexpected situation at home, we never open the TV box till today. Today my husband removed the TV from box. After installing the legs and putting it on TV stand, he plugged the power cable in socket. He used remote control which came with box to switched on the TV. TV started and he gone through initial set up. We don't have cable. so he connected TV to wifi. He clicked on YouTube app where TV prompted him to update the app. He did that. Then he tried to play kids video (Peppa Pig) on YouTube, screen went dark. Nothing is coming up on screen. Whenever I turn on TV, blue color is showing on screen. Does any one experience this kind of issue? If yes, what did you do fix it?
I am feeling really bad that we didn't open this TV when we bought it. We could have noticed this issue right away and could have returned it to retailer. Appreciate any help you can provide. Thanks in advance.
