Split screen with a double image.
I have a 55” Roku 4K TCL TV. The internal boards were changed by a qualified tech to repair a problem. Unfortunately, after the repair the TV is now stuck with a double image on the screen. It’s like the screen has been split down the middle and the images are identical on the left and right sides of the screen. This tv had all the internal boards changed by a qualified service tech to repair a problem, but he left me with this worst problem. He tried many times on the repair visit to use the remote to correct the issue with no success, and the tv has be reset to factory mode many times. Nothing has worked to help this issue.
