Hi Guys,

Experienced an issue with my Demo Man today that I am hoping to get some assistance with.

When the ball is directed to the elevator for the claw to pick up, the routine where the ball raises and the claw move to grab it never happens. I have gone into the test mode and the elevator will go up and down when depressing the test buttons and the claw will move left and right again while depressing the test buttons.

So when this situation occurs, the machine after a few moments will discover that a ball is missing and try to locate it but it never does. It is sitting on the elevator. Sometimes, after doing a power cycle it will find it and then release to the playfield but the whole scenario repeats when the ball is again shot so that the elevator can raise it.

Any help/direction is greatly appreciated.

Thanks Lloyd. And my luck it is in the far back of the game. Oh well. Will look and report back

Hey Buffaloatx

MANY THANKS Very helpful. The ole opto issue, hmmm. The game had been working just dfine since I picked it up 6 months ago. ALl good, not a hiccup. The balance of the game seems to work just fine Buffaloatx. Not sure I have a manual with that game but I think I am going to find one/get one. Thanks very much!!

i'll plan to use my iphone camera to see if the opto is good back in that area. Thanks again Great assistance.

I can see the ball sitting in the elevator and there appears to be an opto where the ball sits. Maybe this is the root of the problem as if the machine does not see that the ball is there, the routine where the ball raises and the claw grabs it will not start?

Hi Fellas,

Quick question. Thought that if I use my iphone camera, or any electronics camera for that matter, that if I point it towards an IR source that I should see the led glowing??? I have tried this on some misc a/v remotes that I have that are using IR and I cannot see any indication of the emitter glowing. What am I doing wrong?

Thank you

George...

Thank you sounder. Yeppir. Just found it on the net. Should have looked before I posted a question. Thank you and sorry

Ok. Did the switch edge test on the opto in the back which identifies if there is a ball on the elevator and it registers in the test. Must be ok. Looking at the small PCB that is at the bottom of the elevator mechanism. Wiggled the connector and turned the game on and put the ball in the area for the elevator to work and it did. Then it went back to not working but may be onto something. Attaching a picture of the boatd

Believe this is the elevator opto PCB Anyone ever remove one of these? If I just takeout the four screws affixing the board will it slide out? Think this may be where my issue resides. Poor connector or dirty/defective opto. Would like to just slide the board out to do some testing.

Looks like I should just be able to slide that out.

Boatd is out. Little in the scuzzy side.

Ok. Cleaned the board and plugged it back in and did the switch edge test and the opto is working there. Could have been just dirty as board was a bit dingy. Will reassemble and see what happens

Nice clean version.

Got it guys. Those Sabine dirty optos. Thought that board would be a whole lot more difficult to get to than it was. Not so bad. Nothing a nice bath of 92% alcohol and compressed air can't handle.

THANK YOU guys

George

Hey spyder

Thank you, me too. Just hate like hell when stuff is broken. One thing becomes ten things and I just don't want that in my collection.

Your contribution was helpful. Thanks again

Hi Guys

Seems like I still have an intermittent issue with he elevator rising when the ball lands in the appropriate spot. Cleaning the opto appeared to help but I am wondering if anyone out there understands the technical flow of the game to maybe assist? The ball needs to land where the elevator can lift it. That opto that senses the ball is working. Then the elevator needs to lift the ball to the crane. Here's the question. If the connections to the opto elevator board are not 100% snug, could that cause the elevator not to rise? Seems like after the machine went into ball find mode when the elevator did not raise the ball, the vibration from the solenoids triggering was enough to send the elevator up and the sequence worked

Would appreciate your thoughts

Thank you

Mitch,

Have you experienced what I am describing with your game?

G

trying to determine if the elevator opto board is most likely the culprit here. I can certainly take it back out and re-heat the connections and replace the opto assembly but just want to have a reasonable expectation that I am not chasing down the wrong trail??

Good point Mitch. Thank you
