Just picked up a Turbo for a friend along with several extra boards.Monitor lights up-good raster ect -controls all seem to work. One board just makes noise of engine rumbling - no coin up difference game play nothing .Another board lights up the high scores and seems to play blind - hear engine revs-score works-steering and acc.seem to work by the sounds made when moving them . Third board does same thing but does not display high scores - just current gameplay score . Voltage has been adj to 5.10 and the board connectors cleaned . Have not reseated any game board chips . One led light is always on - one goes on-off with game play third one stays lite all the time. QUESTION is : why no video if all connections are present and correct and the monitor is functioning while swapping out 3 different boards ? Thanks for reading and any input . mike
