I bought a Mitsubishi 65869 last september, about week or two later I noticed that at startup the tv would show a blackish green screen with green lines bowed up for about a second and then go away. I went to the store were I purchased it and they sent out a tech. He said it wasn't anything serious and would be in contact with mistubishi to see what the problem might be, he thought it was the green gun turning on before the other two. I finally heard from him last week, he said it was nothing to worry about. Has anyone experienced this? What should I do. I'm worried it will eventually turn into a bigger problem.
