My south park switch for cartman hole is not working. I have changed the switched and traced all the wires. Everything is good on playfield side of the game.

I used a jumper wire to narrow down that problem is on the board.

I changed the 8 transistors, the lm339n chips, 74HCT273 at u203, 74HCT275, And 68B09E's. None of these changed anything. Occasionally the switch does work with jumper but often take 10-20 trys before registering.

The guy that helps me fix them finally said he may have changed that switch (soldered with game on)

That has happened to me in the past but usually the lm339 fixes it.

Can anybody help????

Sent the board off for repair and it still didn't fix the issue. Please watch video and see if anyone can help me!

Thanks!

Switch 45 and 46 both have the same weird issue. I'm bypassing the entire playfield so it mlhas to be a board problem.

I talked to my repair guy Chris hibler and he reassured me it had to be on the game. The switches are meant to test like that.

I replaced the switch for a third time and the game works as it should. I just had two bad switches in a row some how!?

Lucky me thanks Chris!!
