Mr. Pinball Tip:

I've noticed that many early Bally and Williams games have poor solder joints where the connector pins are soldered to the circuit boards. This can result in intermittent problems or an all out failure of the game, depending upon the particular function of the connector. The best strategy on these games is to remove the boards from the machine and desolder and clean the connection. Then apply a very small amount of flux (rosin or electronic ONLY, do not use acid based flux!) to the connection and resolder the joint. Some of the problems I've encountered because of bad solder connections are listed here: intermittent switch registering (Bally games), intermittent or no sound (Gorgar and Firepower machines), playfield lamps out (almost all Williams games with lamps mounted to p.c. boards) and inoperative games.
