Forceflow, I would recommend you take the whole thing off the game. Meaning, the POA and the motor all at once. Just unscrew the motor assembly and bracket from the rear panel and remove the mini playfield with the motor all at once. This way you can set it on your workbench and have more control and more space to work with. Then you can try the methods mentioned above to try and get the screw out. I'm restoring my IJ at the moment and it can be done. I recommend you carefully drill it out so you won't damage the shaft.
