I was doing some research but did not find an answer. I was wondering if someone could shed some light on this. This is a NEO AES, USA model with serial 015686. It is a NEO AES serial board with the daughtercard on the right front side. Not by me, but UNIBIOS 3.0 was installed.

Here is the issue: On every cartridge played, it will display random vertical lines through the sprites and/or background. Some parts of the image are clean at the same time. As the sprites scroll across the screen sometimes they become fixed and then go back to being "lined". Other than that, All audio and color is accurate, no random restarts, and no other problems. Game plays fine otherwise. It looks almost like a dirty NES cart when it is running.

What I have done so far: Cleaned system pins and game carts (no change), for the heck of it I also replaced the capacitors. Neither action fixed the problem. When booting up it displays a white screen due to UNIBIOS 3. Not sure what to do next. Any thoughts? Thanks in advance!

First pic to show sometimes it looks ok, but majority of the time something is distorted(pics 2 and 3). This happens with ALL games, not just this cart.
