Hi everyone, I'm working on a RIC monitor Model # X-970 that has a severe horizontal jitter when displaying in DOS mode. When in Windows, it looks OK, but the center part of the screen is a bit darker than the rest. Not much, but noticable. I'm betting that I have a bad filter in the power supply, but so far haven't found it. Thanks in advance.
