Game dead at boot after high score knocker ring.
Thanks to your guys help, I got my High Speed back together after completing a top side teardown, switching over to LEDs, and doing my first playfield touchups (which turned out quite nice).
I fired it up to play a game and everything went perfect! I was doing so good, that I got a free game! When the knocker went off, the siren sound went higher pitched and higher pitched while nothing happened in the playfield. After 20 or seconds I reset the game. Now it doesn't boot. When I say that, I mean the lights come on everywhere but the display, and pushing the start button does nothing.
I had to leave for work, but visually inspected the fuses and they looked good. I have included a few photos in case I am missing something easy.
I have the parts to replace the board in the upper right (power control board I think it's called) and re-pin the molex connector there (was going to get to that), but wanted to verify what was wrong first before possibly creating more problems.
Any and all help would be greatly appreciated.20200211_063344 (resized).jpgqqw (resized).jpg
