My RCT was just sitting in attract mode and I could hear a repeated power up sound. I went to examine it and the DMD was resetting, the usual boot up messages showing.

I played a game, and during the game the game rebooted again. I powered it down and on and let it sit in attract and 10 minutes later it started to do the reboot cycle again.

I changed my batteries just to be sure, but that had no effect.

The game has been fine until now, just started out of the blue. Any help with what to check next would be appreciated. thanks.

thanks for the replies. I will start with the easiest and keep going from there. I will update on what comes of it. Thank you.

It must be a loose connection, because just removing the backglass and lifting the dmd panel out to take a look around, and putting it back, the problem has gone away. It was resetting repeatedly before, now I've had the machine on for an hour or so, and it hasn't done it again.

Ok, here is the latest development. The machine isn't rebooting repeatedly, but when power is off and turned back on again, the machine does not retain any memory. Free Play, etc... is all set back to factory.
