I picked up an I500 and all 3 of the flippers are working, but very weak (can't make it up the ramp). The fliptronics boards and coils had already been swapped. Measured TP6 and got 75.4 VDC. As I understand it, game was working fine and then one day all three went weak. I haven't rebuilt the flippers yet, but it would seem weird for all 3 to go bad at once. Thinking it's got to be a power issue.

Thoughts?

Thanks,

Jeff

Thanks LTG. I'm thinking what I'm calling the fliptronics boards are the same as what you're saying to clean - correct. Old boards removed with problem and new ones installed and the problem still exists. I'm sure that there are wear and tear parts that need to be replaced but I thought it would be weird that all three would become problematic at the same time, making me think it was a power issue.

Thanks for the feedback. So far, I'm thinking the next thing to try is to swap out the driver board unless someone else comes along with another recommendation.

Already try that with no gain, but thanks for the post.

Swapped the driver board and problem stayed with the machine, so I'm guessing it's not there. Pulled apart coil mech and all looks good there.

Anyone got any other thoughts?

Quick update. I was calling the "Flipper Opto PCB Ass" the Fliptronics Boards. Swapped out the "Fliptronic II Board Ass" and the problem went away. In the process, I some how lost the launch button. Didn't work with the new board, even though the flippers were fine. Swapped in the old board and flippers are weak & launch isn't working.

Problem is on the Fliptronic II Board Ass.

Pinball's are such fun.

For the launch button - switch is working in switch edge & coil is working for auto plunger on coil test.

Shooter lane switch also works.

Launch update - reset ribbon cable and now it works.

Now, how do I figure out what's wrong on the Fliptronic II board that's not giving me full strength on the flippers?

Thanks for the help.

Status Update - Thanks all for the guidance. BR on Fliptronics II Board has been replaced and the game is acting fine. Thanks again and big shout out to Mike Schudel.
