My LOTR keeps shooting balls back into the game on the multi-balls even when the shoot again is no longer lit. This is especially happening on the ROTK multi-balls. I have gone into the diag menu into the "In the Trough Clear" and its showing 5 balls! (see attached pic). The small board on the VUK to get the balls back in play appears to function properly as it was swapped out with a CSI one and it worked on that PIN fine.

Any suggestions where to start troubleshooting this issue?

Hey guys thanks for the tips. So in theory, since my soldering skills suck, if I swap out the mini board with CSI, it should work and stop this behavior from happening correct?

Oh yeah, to properly solder reflow, do you need to remove the old solder first then apply the new?

Thanks for your help!

Hey now blizz81, it would be a good problem to have in theory, but I have had the VUK coil connections break down and eventually burn out the transistor on the board and smoke out from being overworked! I have replaced both parts but know it will happen again if I don't fix the root cause of this problem

Hey guys, as suggested I had a buddy reflow the solder on both boards and it worked for about 2 minutes before reverting back to showing 5 balls and even randomly firing balls during games

I am happy to say that replacing both boards with brand new spiffy ones solved the problem once and for all. Thanks for your help fellow pinheads LOTR 100% back in operation!
