Title: F-14 Tomcat Lower display not working
Post by: havarob on May 19, 2016, 10:18:10 AM

I have an F-14 Tomcat pinball machine and got everything working except the lower two displays, they are blank. The voltages on 3J2 Pin#1 -102 volts  Pin#3 +96 volts and Pin#6 is 4.9 volts. Looks like the voltage going into the display board is good. The upper two displays are working perfect. What should I check next?

Thanks

Replacements are pretty cheap. You can get them in colors too, like red for F-14.

What would be the super and lower? Do you mean desolder the upper display and put it on the bottom?

Thanks for your help

Auto correct error - oh right because it's 4 displays on one thing - wasn't thinking clearly. Yea that's a major pain and they are likely out gassed.

Have you reflowed the headers on both ends
