I have a Neotec NT-25E that was working great for years in a Cruis'n Exotica conversion.
Recently, it started "rolling" horizontally, after being powered up for a few minutes. It almost looks like a loss of sync, or a HFREQ problem. If I adjust the H Hold knob on the remote board, I can get the rolling to slow way down, but the picture is still off and unstable.
I pulled the chassis and installed a cap kit, and replaced the flyback with a new one from Arcadecup.
Although the picture now is nice and crisp, the horizontal problem still remains.
Does anyone know what this could be? I read that IC401 on the chassis could be the problem (an LA7851), but wanted to see if anyone had any ideas.
Thanks!
