my Outrun game was playing perfectly until yesterday. The only way to get something to appear on the screen is to put it in test mode which appears correctly but once I exit the test mode the screen goes blank and the no game at all (no sound no picture nothing. Any ideas?

Does your board have a suicide CPU on it? Google Hitachi FD1094 for an image on one.

No, I can't see that chip on the board.

Cold solder joint somewhere?

Basically it could be anything on there that's stopping the CPUs from running the game code. Reseating the socketed chips and inspecting for physical damage is about all you can do without a logic probe or an oscilloscope.
