The MPU is resetting or locking up in play. When this happens, the flippers quit working and the game start up in to attract mode, with the sound (heart beat) playing in the background. There is nothing that points to the flippers or any solenoids that may be causing this issue.
The board did have battery damage in a very small section of the board. The chips, IC5 and IC19 was removed and the board sanded down to shiny copper traces with a vinegar wash afterwards. I repined all the connectors that I found that had green goo in the connectors.
The male and female interconnect has been replaced along with all the headers.
I also recapped the power supply high voltage and 5 volt section.
I don't have much system 6 board work experience, but I'm thinking that the reset section of the board is acting up. This is just a guess.
Where do I go from here?
