When I boot up the machine I'm getting switch failure please check T-Rex switches. I've checked all T-Rex switches and they all work. Left, Center, Right, Up, Down, and T Rex Trough all of them work in the game play and test mode. I removed the diodes on one side from each switch and tested them. They all tested good. Everything works great but still have this switch failure msg. at boot. I'm wanting to sale this machine or I wouldn't even worry about it, but I don't want the buyer to think something is wrong with the machine. Is there Anything I'm missing?
