i just got an ice cold beer, and it will not play . -
when you turn it on, it makes the turn on glug glug glug noise, then the left motor keeps trying to pull the bar down, and will not stop.
if you try to coin it up, here's what it will do - it will not make any other noise, however it will show 0 points, the 100 point counter, and however many credits are left. it will also light up the #1 hole, but the right side bar will not move.
the motor on the left bar keeps running and will not stop till the machine is unplugged, whether it is coined up or not.
i checked the cherry switches for the limit switches and tried swapping them out with a known working one, no luck. the board had a tag on it saying there was a bad q09, q16, and q17. i replaced q16 and q17, (couldn't find a tip125 at rat shack), and when i turned it on, the limit switch did slow the right bar down when pushed on, but then it smoked q17, and now it's back to doing the same thing.
what should i be looking at as far as fixing this? i know i need to replace q9 and rereplace q17, but what else should i be doing? already checked all socketed chips and cleaned the edge connector. i checked the test point voltages and tp1-3 and 3-4 were correct. tp 5-6 showed 10.5v or so instead of 6v, and tp7-8 showed 39v instead of 32v.
also, there are three or four connectors in the bottom of the cabinet (molex connectors) that are plugged. they are labeled g, l, m, and n. i can't find any places for these to go so i'm assuming they are for an optional ticket dispenser, is that right?
i am not good at testing transistors, so if anyone could in layman's terms tell me how to test those tip120-tip125 style connectors i would appreciate it.
also, the traces for these are somewhat destroyed and missing by whoever did previous work, as it was horribly soldered, but i cleaned up what i could and ran a couple of jumper wires and everything has continuity now.
can someone point me in the next direction, please? i'd much rather fix this than have to find another board...
