Can anyone let me know where I could go to find out what the leg lights mean that are on the game board? I have a twin model and on one of the screens I am not getting any of the background screens. During game play all I see is the speed, time left to play. I don't see the car or the track. I switch the top board with the ram and Roms and I get the same result. The main bottom board has four rows of two leds. They are marked led 1, led, 2 led, 3, and 4. On the working car I have two green lights. On the bad game i have one green and one blinking red. If anyone could let me know where I could go to find out what that means that would be great. I have the Manuel and nothing is notted about the led lights.
