I was thinking it may the a fuse, the system doesnt power up, the geensis does obviously, but no loading screen or nothing, it stays black when i power on both units. I've disconnected all ribbon cables and cleaned them with rubbing alcohol, and taken off the connector plate and cleaned where the mainboard goes and where rthe genesis plugs into. There are 4 variable resistors under the laser housing, and i was just wondering where those resistors should be (ie: where the square edge must be pointing as they only have a 180 degree turning radius) The fuse, i'll need to know its specs if i am to replace it. I'm also going to check for a bad capacitor, they tend to cause problems if one is bad. I remember there was a page posted which showed what fuse to use and installation instructions, I was wondering if you have that page handy as well. and so far, thanks for the help Arakon.
