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?

try doing a factory reset. sometimes it clears out errors .

Mine does that also. It says my up/down switch is failing, yet my t-rex works just fine. I haven't poked around too much because I'm afraid to mess with something that is working. We've reset it a couple of times and changed the chips from the old/new and back, and nothing changes. Good luck.

Quoted from Phatchit:

Are you talking about a factory reset from the Audits and Adjustments menu? I've done that as well. Is there a hard reset that I can do, or a reset of error msgs?

Check all the ball trough switch diodes and switches for shorts... as I recall one or more
of them are in the same row/column of the matrix as the T-rex switches.
