ive a small problem with a barcrest 1980's ghostbuster, just put a replacement mpu4 in and got it up and running but the lights for the buttons seam to be all over the place, the cancel and reels dont light up at but all bulbs are fine, when it holds the buttons for take cash, take feature and start flash and if you hold any reels the third reel flashes as if its the cancel buttons light and the light corrisponding to the held reel stays on, rather confusing when your trying to play it, has anyone got a service manual for this machine or any help would be nice
heres a piccy of the machine
