My mistake, the model number is TV37C40, not 37C40. From a distance of a few feet the raster looks brighter and greenish. Close up is when I can see the lines and there are thousands of them (very thin), unlike retrace lines which are very thick and easy to see from a distance. Thanks.

Those green thin lines throughout the picture is usually vertical retrace lines, usually blanked out in a healthy TV. Retrace can be seen if a certain CRT gun is set too high, or if there is a CRT internal short. Phil Philip Bader Jan Phyl TV Inc. (estab. 1976) 3420 Recker Hwy.
