Hello everyone,
I have a Mata Hari here that normally works pretty great, but sometimes the flipper just stop working and then a few seconds later they work again before stopping again. Usally just restarting the machine fixes the problem and I can keep playing for a few hours without a problem.
I also noticed when this problem occurs I can hear a clicking sound probably coming from the backbox(?), but I'm not sure if that's related.

Lastly I have to say I'm a complete newbie to pinball repairs and don't even know where to start looking, as this issue doesn't occur every time.
Maybe some of you have an idea what this could be and where I should look to fix it.

Yeah, one time it also reseted itself, but normaly it does not. Will that make any difference?
Alright thank you, I will check the connectors and if the issue persists, I will report back.

Thank you as well! This definitely helps me and gets me an idea what I should do next. I will check all that on the connector.

Redoing the connectors seemed to have solved the problem for now. But I guess reflowing all the solder joints would make sense and I plan on doing that some time in the future.
Thanks to everyone for their help!!
