I recently picked up this CRT HDTV and I notice what looks two color impurity spots on the left and right side of the screen. These look pretty much the same as geomagnetic related spots you see on the corners of some CRT's but these are not in the corners but about 3 inches from the edges but near the center of the screen. One is a greenish/yellowish spot and the one on the other side is a magenta like spot, they are faint but you can see them with a bright colored (or full white screen). The spots look like they might be something with the yoke or some sort of geomagnetic problem (though again that is usually only effective when the spots are on the corners), my last though was that this might be some sort of shadow mask warpage (that would suck!) ANY help that any of you could provide would be excellent.
