I recently had both boards for a Color Classic recapped and tested on another system. When I placed them back into my original system, the video showed color bars on the sides plus shadowing object on the display. I ran through the video adjustment instructions in the CC Service Manual with little changes. I used the Display Service Utility app under System 7.1 and the Crosshatch 1 pattern to check the convergence. I get three colored vertical lines instead of single white lines. See pictures attach of a typical screen plus the test pattern.
Does anyone have an idea of what could be wrong and how to correct the problem?
