Samsung TV Displaying Dual Images. It appears as 2 of the same images offset from each other. There are also some lines in the images. Talked to samsung and they wanted to send a tech but I simply can't...


Overlapping video signals are generally adjustments made when turning various pots on the rear circuit board. You may need the service manual to follow the directions on how to reset and stabilize the picture. If you cannot be your own technician; you have no choice or other options.
