I recently picked up a Data East Royal Rumble. The game does have some issues that need to be sorted out. First off, the DMD keeps flashing with the message "Display Version." The game will go into attract mode, and I can start a game and play it. Problem is, the display won't stop flashing this message. Any ideas?

Also, I'm having flipper issues, specifically the bottom and top right flippers. The left flippers work fine. When I push the right flipper button, the bottom right flipper will sometimes go up and down without a problem. Other times, the flipper will get stuck in the up position. Now, the other right flipper on the upper playfield doesn't budge at all. It doesn't move when I push the flipper button, and it takes one heck of a time to move it at all. I've read somewhere about testing to see if the problem is electrical or mechanical. Whenever the bottom flipper is stuck up, it will go back down when I turn the machine off. The right flipper on the upper playfield doesn't go back down when the machine is turned off. Do I have a problem on the flipper boards? If not, what else can you think of?
