I have colored horizontal lines on my Roku 50” 4K Smart TV (onn. [wasn’t a device option] Some lines are stationary, while other flicker between vibrant and faint They show up better on certain (usually brighter) colors And are faint and barely visible on other, (usually darker) colors As for solid colors… On Red, the lines are blue and yellow. On Pink the lines are blue yellow and a bit of white On orange the lines are blue and yellow On green the lines are blue and red with a bit of fainter grey On blue the lines are dark red (almost black) and yellow on yellow the lines are red green and blue On purple the lines are cyan and dark red When watching tv or playing games, they are usaully not that noticeable but when you notice it, it becomes very annoying. What causes this? And most importantly how do I fix this? (Or can I?)
@spencerc22 that looks like a driver board issue. Either a bad gate driver or a bad board. The driver boards are the boards that are connected to the panel via small ribbon cables. They are non-rrplaceable. Of course check for a burned or otherwise damaged component on those boards as well as loose connections etc. Ultimately looks like a bad panel
