I have a 15" Megatouch Evo Ion running 2014 software that has been working fine, and one night all of a sudden, it goes to the setup screen after finishing a game of RUN21. I reboot and it goes through all the checks and boots right to the setup screen. I try to quit or go back from the setup screen and it goes to the gaming screen for 1 second and goes right back to the setup screen. I have replaced the I/O board and it still does the same thing. Does anybody have any ideas or suggestions? I would REALLY appreciate it.

sound most like a software issue.... boot the machine with dipswitch 4 and 7 turned on to do a complete memory clear and reset and see if it smartens up
(depending on which machine configuration you have) check and make sure your button for the system setup isn't being pressed down by wires or the door or getting mashed down by something in the cabinet. see if disconnecting the cables and exiting setup makes it stay off or continue to go to setup.

Sounds like the setup button is being shorted.
As mentioned, I would check the OSD board or wire going from the OSD board to the IOboard. Best way to test for a short would be to remove the OSD wiring cable from the IOboard , and if they security key is in the OSD board (usually is) put it directly in the IOboard.

OK LILSHAWN, I booted with DIP 1 to access the 4 & 7 through the screen. When I ran it, it failed (see attachment). Not Sure what is going on?
mahkeymike, I inspected the wiring from OSD to IO board but I'm going to need further explanation of putting the security key directly into IO board.
I appreciate the help!

I never seen those errors. It looks like your hard drive is hosed. You got two options, try a reinstall, or buy a new hard drive. I have 2014 pre installed if you want to go that route. PM if interested.

I ran the 4 & 7 DP switch again today and everything checked out normal. Setup menu when I run hard drive check it says passed. The I/O check only makes it as far as the setup button which has a green light. Calibration or channel checks do not happen. Tried 3 I/O boards and all go directly to setup menu so I know it's not that. Could it possibly be the hard drive?

Could it possibly be the hard drive?
yes. if it's still an original drive, just replace it. it's probably got 40,000 hours on it.

He sent me pics. Its an old ide drive. Looks like it originally had 2008 on it, so yeah it probably have a lot of hours on it.

Tried new hard drive and still doing the same thing! Stuck on this screen.

Setup button has to be stuck closed. Since you replaced the IOboard, it has to be the OSD board. Call me and i will help you find the culprit.

If you have a multimeter test these two pins in RED
If you get continuity, then there is a short in either the wire cable, or the OSD board itself.

OP called me. We sorted everything out. It was indeed his OSD board, or his OSD cable. We relocated his Security Key and pulled the cable and its working as it should. There really is no need to use the OSD for setup or calibration since the evo has easy access to setup and calibration on the IOboard. At least the OSD still works for Auto adjustment of the Monitor.
Anyway, just wanted to give everyone a heads up incase OP never responds.
BTW, OP is a really nice guy. Great to work with.

right on, the wiring in these machines is such a cluster, wires get pinched, folded, mashed all the time\
