Neo Geo MVS MVH SLOT 1F won’t boot

KingJavo · Feb 17, 2025

Hi, I have little to no technical experience with my board. It has the universe bios chip installed and a battery upgrade. I can take more pics but here’s what happens when you boot up. I get power and see stuff on the screen but it just flickers and you hear a repeating blip sound.

Any advice?

Did you make sure the bios was socketed all the way in place?

Yea, I'm pretty sure. I actually replaced the old one just to test it. The board was working fine. I pulled it out and had it in my closet for 6 months or so and now I go to use it and it's doing this?
