Hello, we've had our TV since 2018 and it started doing this a week ago. We tried doing the screen diagnostics picture test, turning it on and off, unplugging it, and nothing helps. It comes and goes but it's been staying on the screen longer than the first few days. Please help :(
This is going to require service since it appears on the picture test. You can use the following link to locate a service center near you: https://www.samsung.com/us/support/service/locations/
