Pixels on tv screen?

rokkee4 since this TV is only six months old, this should still be covered under warranty. Just for academics you do want to try all inputs to see if those lines are appearing with all inputs. Going by your description I would check the T-con board or the panel. It will depend on what your screen displays. Also check to see if the menu displays properly or if that is full of lines as well. Post some images of what your TV shows with your question so we can see what you see. Use this guide Adding images to an existing question for that. Here is how to replace teh t-con board if that is the issue.
