Escape from the lost world bally opto issue?

[njay]

Hi All,

my bally is starting to act up again.
when starting the game sometimes it complains about 1 ball missing but it is in the correct lanes

when i gently push on the opto board or molex connectors it works again
when looking at the molex connectors it seems fine all the cables are correctly connected. can anyone help?
are the boards broken?

so i need to remove the two board and resolder them?
no problem !

will do so tommorow thanks for answering

well i think i resoldered the molex pins but it crappy work and my solder skills are not that good
what i also see is the molex connectors slide over the pin but are loosly you can easily slide them off
i placed a piece of cardboard between the two molex connecters this will give a little pressure to the connectors stay on so far after 12 games no problems but that did work before
