Hi Decided to try my luck and see what might be wrong with it myself. So took the back cover off and one of the cables was loose so i pushed it back and guess what… it’s working fine. Very good news for me. if anyone is reading this, don’t give up on your tv take the cover off and look for loose cables 🙂 Luckily for me it worked in my case Good luck
