So here's what my MSX is doing https://youtu.be/cKYXDu1Yew4
I haven't used it much in a while, but when I had been testing various systems with the OSSC I noticed the MSX was acting up some where colors were heavily bleeding to the right and wiggling the cable (maybe by coincidence) seemed to help. I thought maybe my RGB cable was flaky and I'd take a look at it when I had time. I turned it on a few weeks later and after a few minutes of a stable picture it got stuck doing similar to what you see in the youtube video.
Tonight I took out my RGB cable (actually a RGB RCA breakout box) to verify all my connections and soldering and everything looked fine. I hooked everything back up and it worked great for maybe a whole minute or two, then started acting the same as if there was no sync. Even If I just use composite video output from the RCA jack built into the MSX it's the same result except black and white.
It appears to have a Sony CXA1145 video encoder and I verified it's getting 5v. I also tapped composite video straight off the encoder and ran through a 220uF cap for testing but it didn't help. I'm pretty confused since it's barely been used in the past 2 or 3 years and has been sitting in the same spot undisturbed. Got any good troubleshooting ideas?
