If you're not familiar with debugging CRT rear projection convergence, the process can be time-consuming and frustrating. Here are some practical tips that can help streamline your workflow and improve efficiency: 1. Before starting, check if the convergence center is off. If it is, make the necessary adjustments first. 2. When doing coarse adjustment, start with the green (G) color for the three primary colors, then move to red (R) and blue (B). It's best to work in monochrome mode initially, and then switch to GRB coincidence mode for final alignment. 3. Avoid clearing the convergence software unless absolutely necessary. This can cause unnecessary reconfiguration. 4. During the process, it's a good idea to save parts of the settings—especially the storage key—to avoid losing progress. 5. There are typically 11 steps in coarse convergence, but not all need to be adjusted every time. For example, items like CORNER and PIN-H are often left untouched. 6. Adjust LINEAR and SIZE-H together to prevent linear distortion. Similarly, KEY and PIN-V should be adjusted in tandem to avoid corner curling or other distortions. One should not be over-adjusted without considering the other. 7. Some fine-tuned EASY items are usually not adjusted. Be careful not to over-adjust any single point or line at once; always consider the overall effect. 8. Don’t adjust the user machine’s coarse settings without proper judgment. First, determine if the adjustment can be done in user mode or bus convergence fine adjustment mode. If so, there’s no need to perform a full coarse convergence. These techniques can significantly reduce the time spent on debugging and lead to better results.
