Hey Folks!

I’ve recently picked up my first machine (Pinbot of course!) and I’ve been trying to track down a why the top Playfield flashers are not working. Bulbs are good and replaced, sockets are good.
These lights are on the same switch as the ball trough feeder which works fine. However when I looked at the relay at the back right of the playfield that seems to run the feeder the solder job looks a bit brutal (top relay in picture, the one closer to the front of the playfield).

None of the other relay boards have a COIL connection, and it seems surprising to have GND and +28 connected! Perhaps this was a fix to route around a bad relay board? However I do hear the click when running the flasher test.

Might have to replace this. Could someone please snap a pic of what this should actually look like?

Thanks!

Good call, I forgot to mention, all the warming boards look fine, with good connectivity.

They are 13v, #89 flashers. I recently picked up a box from Marco:

Hey Folks, out of curiosity what settings do you play at? Particularly the auto adjustments for things like the drop targets.
Normally I have it at set to the default 20% auto adjust but after a while it has them popping back up waaaay too fast to be any fun.

Thanks for the feedback! I think I will turn off auto adjust as well.

Could also do Cliffy’s fix for the broken top bit on the red ramp. Mine’s broken at the same place, I’m temped to try this:

It replaces U25. You may need to desolder the existing chip and add a socket.

I have the exact same problem, I just need this piece. I’ve found it for sale here:
http://www.pinball.center/en/shop/pinball-parts/playfield-parts/plastics/8963/plastic-9-for-pin-bot

Though it’s a German company and they don’t ship directly to the US. However there are companies that will forward packages so I’ve been considering it. Unfortunately that makes it rather pricey, something like $50USD, so I haven’t pulled the trigger yet.

No, that’s total. The piece plus shipping. Still quite a bit.

I’ll take it! PM sent

Yeah it’s a common switch problem, I had the same issue. Reposing from another thread:

The visor motor by design sometimes goes clockwise, sometimes counterclockwise. If it runs into any resistance it reverses direction. There are two switches on the assembly — one triggered when the targets are fully up, and the other when the targets are fully down. In my case when the motor went one direction it hits the switch on the side without triggering it, but with enough force to make the motor reverse. The fix was to adjust the switch arms so they trigger on both directions the motor turns.

Hope that helps!

Marco’s carries it, they have a diagram showing the external dimensions: https://www.marcospecialties.com/pinball-parts/02-4259

There’s a setting #37 called “Drop Target Auto Adjustment” that over time modifies the drop target timer based on the skill level of the players. It’s set to 20% by default but it can be disabled (I’ve disable it on mine!) Similarly the setting for the Solar Value Auto adjust is #39.

There’s also auto adjustment settings for Energy Value and Planet Reach for special.

My Pinbot has a similar problem, turned out the -12v on the power supply was low, around -10v, which can cause resets on the sound board. It needs to be higher than 10.5.
I was able to fix the problem by replacing the capacitors on the power supply as they were original and dried out.

Same! Got there twice and whiffed it twice. Recently sold my game so likely not going to get another shot.

I reached the sun a few times though I had disabled the auto difficulty setting on the drop targets so I’m sure that helped.

I had this problem with my old Pinbot, likely your visor motor switches need adjustment. The motor runs both directions but if it encounters any resistance it will reverse direction. It will then close again then reopen closing the switch from the other side.
