If you don't have the debugging skills when debugging CRT rear projection convergence, it will take a long time. Let's talk about debugging techniques below, which may help you improve your work efficiency.
1. Check whether the convergence center is offset before commissioning, and if so, adjust it.
2. When performing coarse adjustment, the G color should be adjusted first for the three primary colors, and then the R and B colors should be adjusted. It is recommended to debug in monochrome mode, and finally select debug in GRB coincidence mode.
3. Do not clear the convergence software easily.
4. During the debugging process, it is best to save a part (save the storage key to save).
5, a total of 11 convergent coarse adjustment, for the above steps is only a reference, not every item must be debugged, such as: CORNER and PIN-H items are generally not adjusted.
6. LINEAR and SI ZE-H should be debugged together. You can't adjust one of them too much to avoid linear distortion. KEY and PIN-V should be debugged together. Too big, the distortion of a corner curl will appear on the side. One of these has not been adjusted, and fine tuning is not good.
7, fine-tuned EASY items are generally not debugged. During the debugging process, you cannot adjust a point or line too much at one time, and you should consider debugging.
8. Do not easily adjust the coarse adjustment of the user machine. It should first be judged whether it can be adjusted in the user mode or the bus convergence fine adjustment mode. If it can be adjusted, there is no need to make coarse convergence.
