Hello, I’ve been having this issue with my TCL 55” C70 tv for a few days. There are very thin black horizontal lines coming from the top right part of the panel. They are not static, but intermittent. They appear and disappear at regular intervals and follow a regular pattern. While the lines are solid black on the right, they tend to become lighter (greyish) to the center of the display. They are not even visible on the left. Also, sometimes there are only a few lines at the top right, sometimes there are more lines coming down towards the bottom, as you can see in this video: https://www.dropbox.com/s/0bu8alax9nburx… In the video it appears like a darkening (backlight) problem, but it’s actually specific lines of black pixels. You can see this from a close-up photo (zoom at 100%), black lines on an image that should be consistent blue: https://www.dropbox.com/s/we3hwj8q3x68a4… Any advice about what’s causing this problem? Any solutions?Thank you everyone
Hi @noric , Horizontal lines in a TV are a driver problem in the LCD panel assembly and cannot be repaired. The LCD panel will have to be replaced. Sourcing new replacement TV LCD panels is not easy and if you do manage to find one then it is almost half the cost of a new TV. If you decide to get a new TV, an option to consider is to advertise the old TV as faulty screen, good for parts to recoup some of the cost towards a new TV. Working TV boards are always in demand
