Drop target opto triggered by flipper

[SteveTheGeek]

Hi everyone,

I seem to have a new issue with my Flintstones.

When I use the right flippers (and sometime the left flipper), one of the drop targets opto (3rd for the 4 drop targets bank) triggers as if the target just dropped. This is easily reproducible in test mode.

Have you ever seen such an issue ? Any hint as to what could cause the issue ?

Thanks !

Steve

The first thing I would check for are for any cold solder joints on that opto, and reflow header pins as necessary, as it appears sensitive to vibrations currently...

Bonne chance!

Thanks, I'll take a look at that, appreciate the feedback.

Looking online, I found a post on Caitlyn's blog about the same exact issue with a Flintstones and indeed it was a problem with the flow on the opto pins, I'll test this as soon as I can !

I just wanted to follow up on this, for documentation purposes. The 4 drop target bank opto board was repaired by one of the previous owner and the board work was just terrible. Broken flows, replaced by a wire, etc. Replacing the board fixed the initial issue 100%.
