I just fixed the speech in my flight 2000. The speech went out. Next I noticed 1/2 of the gi bulbs in the back box were out. 3 days later all gi bulbs in the backbox were out. Then I read speech and gi volts are linked. gi bulbs on playfield and all fuses are good. I looked at the wire that supply gi volts in the backbox. red and orange. i looked at the connector in the backbox. I looked under the playfield to the rectifier board which supplies gi volts to the backbox at the red and orange wires. the connector was burned on those 2 pins. I replaced just those 2 molex pins. Now my machine plays better than new.
