Hello to all the arcade PCB enthusiasts out there.

I spent yesterday trying to fix this issue but had no luck, so I’m posting here in hopes of resolving it with your help.

I’m having trouble with the graphics on my Taito F3 system.

Unnatural red ghosting appears on the demo screen, and areas that should be blue show up as red on the instruction screen.

Once the game starts, the cursor frame changes color, and the frame on the course selection screen displays an unnatural purple hue.

Additionally, "garbage" graphics appear over the character icons on the ranking screen.

I’ve tried resoldering the connectors and other suspicious areas, checking for continuity with a multimeter, and disconnecting the fan, but nothing has improved the situation.

Is there anyone else experiencing this problem, or does anyone know the cause or a potential fix?
