I bought the Deadworld mod. game worked 100% before. Put DW in and the lower right flipper just quit. Put old ROM back in lower right flipper still doesn't work. Checked all fuses connections etc. Ideas?? Thanks in advance.

the flipper still didn't work after I put the old rom back in. Could I have knocked something loose or blown something?

I got t working with the old ROM in. Put deadworld ROM in and it quit again. Flipper fires fine on coil test. As far as switch test the upper flipper works so I assume the button is working fine. All fuses checked with a multimeter.

What now?

Solenoid test works-flipper fires. switch test flipper does not register. The other 3 register when button is pushed...

Lower right isn't working. Upper right is fine.

Nothing?

So s it prob the opto board or the connections to it?

I id the switch test. Upper right and both left flippers register fine. lower right doesn't register at all.

Im gonna switch the entire board with another one that I know works.

Working now. Was connector for switch 1 on the opto board. Jammed the wire in the connector and its working now. I need to buy the t-tool Thanks for the help!!
