Reels spinning backwards

[brianfink]

Ok so yesterday when I turned on my triple red white and blue a funny thing happened. The reels spun backwards and I came up with coin in jam error. So I tried reseating the board, I/O cards, removing hopper/BV, still same problem, then I reseated the SB,GME booted up and reels spun backwards again but this time after I closed the door 2 times the coin in error went away and the reels spun in the right direction and everything seems fine. I was thinking it was a connection problem between the board and backplane but I don't understand why the reel spun backward at boot up and then forward after the error cleared.

Reels spinning in a unusual way so security and other casino employees have a visual cue that something is wrong.

Today I turned the machine on again and this time the reels spun in the right direction but the coin in error came up again I closed the door a couple of times and the error would not clear this time I decided to just walk away and leave the machine running. So about 15 minutes later I want back and shut the door again and the coin in error went away but I got a machine type mismatch error I checked key chip config and machine type was already set to upright. I closed the door a couple of times and the error would not clear I turned the machine off and back on and it booted up and worked fine without any problems. When I first got the machine I did 3or 4 ram clears like I do with all machines and It is a 504 board with sg 363 and the proper sb for triple RWB 3cn it does have a weird version NX5 but I have another machine with that version chip that seems fine. I guess my next step is going to be to try different game chips unless some one has any ideas.
