Recently got myself a Meteor and had it setup downstairs. Game played great, but the settings and high scores were acting up so I bought a nvram board for u8/u13 on MPU.
I took the head off and took the game upstairs in 2 pieces. Now I am having sound issues. (see video below). The sounds are all muffled and cutting out.
The cables between the sound board and MPU are brand new. I also repinned and replaced the bottom 2 connectors to the sound board as well. I also swapped back in the old ram and that didn't make a difference. I did clip off the remote battery pack when I installed the nvram, but that shouldn't matter. I also triple checked all my connections.
Any thoughts what I should test or check next?
