Vertical lines on Samsung LED TV (UN55SD8000)
I have a Samsung UN55SD8000 TV. It is over 2 years old. I have lot of vertical thin blue lines on my screen. Lot of them on the left edge and some on the right and many across the middle of the TV. I have attached two picture showing the problem. I called Samsung and they did the remote display diagnostic test. He just gave me number of repair guy. Did not really tell me what is wrong. I would think they could tell if screen is bad or some xyz part may not be replaced.
Any ideas on the problem? Will this require replacing my screen or just cleaning the connector to the screen? Trying to see if worth calling TV repair guy or not.
