Did a single lamp test and found I actually have almost a complete row of  lamps 18 28 38 48 58 68 78 non functioning (put new globes in to make sure). The only lamp on that row that works is lamp 88 the start button. Note Red-Grey wire is common to all these lamps. I have checked them all physically, no wires seem to be loose or disconnected, Checked the connector on the board, it to looks fine. I am a novice at all this, and am absolutely stumped by it.
