Hello, simpsons was playing fine then suddenly stopped mid game and " display version 5.0 "came on the DMD. I tried entering the menus but nothing happens. Stuck there. Any thoughts?

Thanks for the reply. No, it won't play. Playfield is lit, not attract mode, but lit. Can't start a game and can't run diagnostics through the menus. Just gives same message on the DMD. So you think I need to replace CPU board?

might want to send it to someone for testing, and repair.
Also verify that all your fuses are good and you don't have any burnt connectors
reseat ribbon cables and connectors from the CPU to the driver board. sounds like a signal is just not getting through. Could be a corrupted rom as well, try pulling and reseating it.

So after working for a day or two, the problem returned. I decided to remove all cables to the boards and clean all the connections with deoxit and reseat. Did not solve the problem. Was talking to someone who suggested the batteries could be dead and that would cause it not to boot up. I always thought the batteries were just to maintain high scores. I was really hopeful that was it but after changing batteries, same deal. I then removed all fuses and tested with a Muti meter. They are all good. Now it seems to be getting worse. The display will now only flash the display version every 20 seconds or so. If I leave the machine powered up, eventually I was getting a message that said "open the door". Tonight I left it running for about ten minutes, heard a ding, then all the play field lights went out. Only the back glass is lit now. Any ideas where I should go from here?

Send it out for repair, the open door message is due to you changing battery's.
Same problem I had.

I took the suggestion that the ROM itself could be corrupted and bought a new one. Sure enough , that was it! Weird thing is, with the new ROM it takes a good 2 minutes to boot up. It has been playing fine the past week or so except for the switch under the TV is now only working about half the time. Never had an issue before putting in the new ROM. Today I played a game and switch was 100 percent not working. Seems odd that the switch was fine before but now has a problem. I pulled the upper play field out just enough to look at the solder joint and it's looks ok. Sprayed a little deoxit in it and reseated everything but same problem. Any chance the ROM has an issue or just coincidence the switch went bad at the same time?
Will I don't think mine takes more than 10 seconds to boot, strange
and it's possible game rom could cause switch problems.
Where did you get the game rom from?
What version #, And did you change all of them with the same version?
I had the latest version to begin with, 5.0, and replaced with the same. Bought it off a guy on eBay who sells the game and display roms as a set. Didn't do anything with the sound roms. I emailed the seller. Pretty sure he has a burner and just downloads the game code from the stern website. Is there a source that would be better? A stern issued rom?
