Check voltages - a low or ripply 5V supply will cause most games to fail to boot.
Another very common problem among games is faulty memory chips. Without knowing what game this is, or anything about it, I can't give you any specifics, but, check to see what kind of memory it uses. Most games, with a bad memory chip, will crash and fail to boot with similar symptoms that you describe. If it uses 4116's, then carefully check the other two DC voltages - missing or incorrect +12 and -5 will cause those not to operate.
EPROM chips are probably fine - those are very stable. I'd focus your attention on the power supply and the memory.
