Hi all,
Need a bit of help with a Sega Saturn I am trying to revive. I got it with VDP1 fault. Removed VDP1 and after trace inspection swapped with my only donor. Worked great so proceeded to mod it and when I tested it again it was back to how it was before. Went down the rabbit hole of changing decoupling caps, all VDP1 ram and still the same. It plays games, but won't show 3d objects, but background and some menus are fine. It also won't show boot animation, but does play the sound, won't show the menu at all, and won't show the confirm highlight when setting the time.
I assume whatever killed the first VDP1 has taken out my replacement, but I have no idea what it could be that is doing it. Any ideas of where to look next? It's a VA7 board.
Oh and if anyone has any donor boards in the UK that might also be really helpful.
Link to photos of it playing a game below.
