Quoted from Fordiesel69:Many many years ago I lost count, I purchased nice blue LED score displays from Brett thru an email. Long before the whole marco ordeal. I noticed when I installed them, very rarly the game will crash and reboot itself. The MPU quits, then goes thru a whole 7 flash reboot sequence. I went thru the rectifier board and corrected solder joints and replaced the bridge rectifier that relates. I also pulled out the -22 board and refirbished it with new electrolytics and did all the upgrades like I always do for these.
If I remove all the displays and put the factory orange ones back in this problem goes away completely. It is not able to be reproduced often enough to be able to diagnose.
Would anyone even know where to begin? I really like the blue LED displays.
The displays are pulling the 5V line down and causing a reboot. Trying running just one or two LED displays to see if the problem goes away.
Check the amp rating of the regulator on the power supply board and make sure it is not one of the cheap china low amp replacements.
