LED Tv screen turned grey

We need a bit more info to answer this. How many devices are plugged into this TV? If what you are talking about is going through the same wire, then I would suggest replacing the wire ( I presume HDMI).

Only thing pluged in is a sound bar and I've removed it to see if it was the problem but it still does it. I’ve disconnected my ipad and iphone to make sure there is not interference.

I can access youtube menu and select tiles but when i go to play a video my screen turns grey\white kind of like the old tv’s when u didn’t good reception from satelite or cable.

@lgtv65 have you tried all the other inputs? HDMI Component Coax etc. This is very important to test since your error maybe isolated to one input. Disconnect absolutely everything and only select one input. Usually when your on board menu works but not your image it is a main board issu. So you do want to check by removing the back of your TV and check for obviously damaged components. Leave this until you check the inputs first. Post some pictures of all of your boards with your question. That way we can see what you see. Use this guide Ajout d'images à une question existante for that.

So i called costco and after being transfered a bunch of times they finaly decided to send someone next week. Thank for the help but now i will just wait for them to deal with it.
