Secondly, the point when the colors were separated, this is a convergence problem. This is a CRT (picture tube, cathode ray tube) rear projection TV that utilizes a red, green and blue CRT to produce the picture. The fact that each tube cannot be in the exact same place physically, when each tube projects it's version of the picture off the mirror to the screen, the red and blue cannot match that of the centered green tube. So The red and blue picture geometry must be modified by the convergence circuit to make the picture watchable. The output circuit has failures after many years due to the heat given off during operation. The technician will likely charge you around $400 to repair.
