I have a Samsung UN46B6000VFXZA television.
I was watching it when suddenly appeared translucent colored vertical lines.
If the tv is off and I turn it on the picture is perfect for about 5 or 10 seconds, then the translucent verticle colored lined reappear.
They do not stay in one place, they move across the screen, and seem to intensify on a channel logo. For instance, watching the USA channel, they have a USA logo on the bottom right when you watch their channel. These colored lines will deepen in perfect alignment with the USA logo, and for any channel that has some type of logo on it.
Can anyone tell me what this might be? The tv is 18 months old, so out of warranty. I would like to fix it myself. I am pretty tech savy with building computers, so I hope I can fix this tv?
I took some pictures of the built in Samsung test image with the lines over laying that test image.
