Ultimately I believe that I am most likely the problem, but I would like some help.

Playing and noticed lights flickering when i hit the flippers. Lifted the playfield to have a look below with no obvious problem. Set the playfield back in place and tried to start a game.

Now neither of the bottom flippers or the upper right lower play field flipper work. Tree pops, trough VUK, state fair also not working.

Seems all coils on the J6 J7 plug are not working (pretty much first half of coils on the coil test). I have checked all the fuses and they seem to be ok.

Thoughts?

K. It seems 70V coils 1-32 are not working. J104, J105, J106 and probably J107. Where is the point of failure here? I'm not a schematic wizard, but it seems that all these things could be traced to a most likely source? Again fuses are good and all connections from play field into the box are good

Read a post where a guy had a similar problem and it turned out to be a dislodged connector pin. Is this a possibility? If so where would that pin be? I'll check all of them but was curious if someone could give me most likely starting point.

Tested the fuses with a continuity tester. I now know this is not the best method. Will retest and get back to you.

Quoted from KingPinGames:

i would suggest calling Frank at JJP

Thanks Chris. My initials still on hobbit from TPF?

Quoted from KingPinGames:

Probably not. I set my machines to reset the high scores as often as possible (I think it is 200 plays on jjp) that way other people get the excitement of entering their name.

Gotcha

Issue resolved. Connector on box must not have been seated well. D701 LED was not lit on board. Reseated the blue/bottom connector outside the box and it works. Lifted the playfield again and it did the same thing. Reseated it again and it works.
Thanks for your time.
