I bought LG UHD 49inch 3 years ago and now the screen diplays horizontal /vertical lines .As per LG Technician i need to replace the panel . Kindly advice do i have to replace the panel , if so where i can order the item through online. LG tech team removed the cables after opening the back cover of the TV and reconnect but still the issue remains same. LG49UF671T
@shan321 it is easily possible that this “screen display horizontal /vertical lines” is a bad panel. LCD panels like the one you would possibly need are not easy to come by. You will need to do an online search based on the label on the back of the panel not your TV model number. The panels may have had revisions etc. which can cause issue for the replacement, thuis make sure you look for the same panel number as you currently have. You can also try and see if you can find used ones on places like ebay, craigslist, pawn shops etc. Post some pictures of what your TV displays so that we can see what you see. Adding images to an existing question There is always a possibility that it may only require a new main board or t-con board
