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.
