Hello Friends - long time! wondered if I might bounce an issue off the group to inspire a new direction of thinking for a flipper issue i've been having.
I hadn't played my DE JP in sometime (never moved, just sat where it's been for the last 2+ years) and when I finally turned it on, the lower right flipper was weak and wouldn't stay engaged -- I thought maybe a flipper rebuild would be in order so I did one this evening and while the flipper itself is definitely more responsive it definitely isn't as strong as it should be (even audibly it doesn't sound as strong as the upper right or the lower left flippers). Worth noting is that the upper right and lower left flippers have always played as they should.
Here's what I've done to trouble shoot:
- I noticed some discolouration on the right side flipper button leafswitch that controls both upper and lower right side flippers, so I cleaned the contacts with isopropyl alcohol (tons of grime came off) but the lower right flipper remained half powered and semi responsive.
- The flipper board registers the button pushes (red lights blink on with the flipper buttons are depressed).
- I've checked the fuses on flipper board (and throughout) and none appear to be blown.
- The backbox cabling as well as all cabling in and around the front end of the game all appear connected and ok.
- Did a rebuild job on the lower right flipper and triple checked the matching of the coil numbering as well as all the soldering/cable placements.
Is it possible my flipper board is pooched somehow? I might have the original one that came with the machine to test (nothing was wrong with it, I just upgraded the board as per the flipper board service bulletin from years ago - the EOS switch one).
If anyone has any suggestions it would be greatly appreciated and I can post pics/videos of everything if that would make anything easier.
Thanks everyone,
Johnny
