Hi all,
I've got a Neo Geo MVH 1 slot when powering up shows just a screen of garbage. There's no battery damage and i cant see any damaged traces. Using a logic probe i noticed the CE is low and the OE & WE are high on all work/backup rams, which according to the truth table for the CXK58257AM rams means the outputs are disabled. Would this be causing the board not to boot? If so where else should i be looking to see whats causing this issue.
