I have a hollywood heat machine. Voltage and cpu checks ok voltage at displays check ok too. With displays unplugged everything seems to be ok sound board and cpu. With the display board plugged in cpu and sound board lock up. Could this be a problem with the U1-U3 chips. Any help would be appreciated. I want to get playing again. Thanks
After 3 months of tracing, chip swapping, prom burning, diode testing, and a ton of solider.... its alive!!!!

check out "pinbxxxx" they have almost all gottlieb manuals and wiring diagrams. Also try "gottlieb pinball system 80 repair" It tells you what the line voltages should be plus diagrams and pics. Good luck.
