I've got an incredible hulk with a strange issue.
The main board is cleaned and all solder work is redone , lines are checked and battery replaced .
The game turns on , plays music , shoots ball and all displays are on.
But start button does not engage the game, bumpers and flippers are not working
Also swapped the board on the right and all voltages are spot on from the power supply .
Anyone got a start for me to look at ?
