hi guys,
I’ve got trouble with a motherboard Zn-2. It’s for sure from the motherboard because I tested with two daughter boards (rival school and sfex2) and the game works on my other motherboard.
With this one, you can see the game with a very dark image and the sync is definitively not good. Without game, I’ve blue screen with the same sync problem.
On the motherboard I can see a repair on one chip : IC603 74LS374.
Do you have an idea where I must focus my attention? Crystal? Sony chips? The 74LS374?
Thanks a lot for your advices .
