"It’s a blown fuse, blown transistor and a bad chip. We have all the parts and will have it up and running this weekend.
Here are details on the issue/fix. https://pinside.com/pinball/forum/topic/simpsons-pinball-party-left-flip-blows-fuse-and-transistor-on-flip#post-8423153" The Simpsons Pinball Party (Stern, 2003)
"We’ve replaced and fixed the guitar lock mechanism at least 5 times. The most recent attempt lasted for about a month before issues started occurring again.
This is the mechanism that keeps failing:

We’ve now welded the bracket at the bottom to stop the bracket from bending and eventually breaking off. We also modified the springs to be larger springs so they don’t immediately get out of wack on the ball lock posts. We will make some adjustments tomorrow as most likely the springs just need to be adjusted slightly. We’ve also ordered an entire new mechanism from pinball life but will only take parts from it and not use the bracket since the bracket is just not strong enough without the added welding."

"Worth noting, this copy adjusts the Walker rule so that a majority of shots will always be lit for them instead of just two or three at a time. Other copies’ default settings don’t play like this so expect scores to be higher on this copy thanks to the reduced difficulty of lighting & increasing “X”." The Walking Dead (Pro) (Stern, 2014)
"Desperately needs love. Flippers desperately need a rebuild, leading to the left ramp and center ramp being impossible, RPG motor works, but the coil to kick the ball does not, so… yayyyyy time to stand around for a minute :(. Kickback is very weak and sometimes binds, making it so that it does its one job (saving balls) poorly. Game has next to no pitch, and leans to the right. $1.00" Terminator 3: Rise of the Machines (Stern, 2003)
