My problem with time machine game continues. When turning on play field illumination lights go on but game doesn't boot up. Thought it was a problem with the l/r relay k1. Replaced the ppb board and it worked for 24 hours and now back to the same problem. Checked the relay with multimeter using the CPU board and it clicks. Must be something before the ppb board. Checked connectors and found the j 5 connector had some burn on outside prong but I thought this was a power out connector post k1. Any advice would be appreciated
