Quoted from BrianJ1337:
So far tech support has had me replace the entire main board, power supply and one other board and no luck and worst part is I broke one of the clips on the main board, doesn't effect anything but still sucks.. The last contact I had with them was to go through every single connection and check.
It's tied to my right side flipper as the translite flickers only on a full press of the right flipper. I have tried other outlets etc but is it possible I have dirty electricity or something and it's not related to the actual connections.? It's definitely got me stumped. Game plays fine but watching that translite flicker when playing just gives me a twitch in my eye.
Have you removed the right flipper assy to make sure the metal plate is not touching any of the GI underneath it?
I do not have LZ yet but I have had many Sterns and some of these often have GI stapled under the Pf by the out lanes, these often are exactly underneath the flipper assy.
If you are telling me that it is flickering under a flipper activation it sounds like something it is shorting when this circuit is activated. It could be very well be anywhere on your hose really but I would start by looking underneath the assy to make sure there is fish paper there blocking the GI from the assy or it might be shorting in a weird way.
See if you get continuity in between the flipper assy and the grounding braid (you should not I believe), if you do, then your GI is shorting the flipper assy.
I am thinking out loud really, and what I am saying might be incorrect so feel free to roll your eyes if these recommendations are stupid.
IF everything is good at the assy, then by following the logic of the flickering being caused on flipper activation I would perhaps inspect the wiring from the flipper to the node board and isolating it to see if this solves the issue.
I think that if you isolate the wiring, removing it completely from the hose it will reveal if there is a short somewhere, maybe there is a exposed insulation somewhere and the high voltage of the flipper is leeching into another.
Last I would try to run a new cable isolating the flippers, and see if perhaps this is caused by a lose connection somewhere, creating more resistance/drawing more power? Have you measure power at the flipper when activated and see what voltage you get and compare it to the other side.
If you have replaced the CPU and Power and everything is grounded properly (have you checked grounding?) then the issue is probably wiring, in my opinion, the culprit is usually the most obvious thing.
Keep me updated I love this stuff.
