Horizontal lines on certain colors on TV
I have a Toshiba 50UL2063DG Android TV, and it was working fine until lines started appearing on the TV, these were basically unnoticeable at first, but a while later, they started getting worse to the point where the lines would start flashing. This covers a large part of the display. Right after turning on, the TV is fine with just a few lines, but after just a few minutes, the lines cover most of the screen and flash. I have done some research and suspect a T-Con board problem, but I'm not sure.

Electric Shock, it won‘t be the T-con board. Horizontal lines are never caused by the t-con board. They are usually caused by a bad panel LCD driver board and sometimes by a bad main board ( not thin lines like on yours). Let‘s see if we can find out more about your specific TV. Start by checking the ribbon cables for tears and corrosion.

@oldturkey03 Thanks for the quick reply. I have actually been struggling to find much about this specific TV, but anyways I have checked every ribbon cable, between the main board and the T-Con, between the T-Con and the LCD drivers, and between the drivers and the LCD. There are no tears, no corrosion and no damage at all.

@ElectricShock can you post some good pictures of your boards and the interconnect cables, with your QUESTION?

@oldturkey03 I have added some pictures of the boards and cables, if they aren't high enough quality, I can use a better camera.

My Toshiba tv model 50UL2063DB has the same flashing horizontal lines issues after less than two years’ usage. Before then it was working perfectly fine.
