Neo Geo CDZ graphical issues

[Konachu]

Hello. May I ask for some support?

On using my CDZ recently I have an issue with the display output. The image will display vertical bars like part of the image is missing.

This is through composite.


I also get the same issue but clearer with Scart.


Can anyone advise. I do not suspect the Scart cable as the composite output also displays the same issue.

Did you ever resolve those? I suspect the graphics chips so if it were my system I'd try inspecting the solder joints there and reflowing any that look problematic
