Hello, I have an older Trinitron computer monitor which has recently started displaying one-pixel wide slanted pairs of blue and red lines. The paired lines slant up, left to right, with the left end of one set level with the right end of the next lower pair. The pairs are spaced about 17mm apart. These lines are only visible on a dark (black) screen, not on a white screen. The image on the screen is not distorted.
Can anyone suggest an explaination for this? Is it repairable? Will it get worse if not repaired?
Thanks, Epi
