I’m baaaack!
Picked up a “rolling chassis” stern lightning for 1100. It looks ok. There’s some issues with the playfield inserts and what I assume is the Mylar lifting, and structural issues-pics attached.
It turns on and does stuff, but that’s about it. I can visually see a bunch of issues, but I’m thinking the main board may need replacing. I’m going to attempt to attach a video of what it does when I attempt to “play” it.

Also, the playfield is probably the dirtiest I’ve ever seen, and I’ve seen 2 playfields-including this one

Maybe I ought to bring ‘er by when it’s done

I’m assuming I should reseat them. I’m going to need a x-acto knife to cut around the Mylar?

I’m headed to Chicago for 2 weeks on business, so I won’t be able to do anything until I get back.
I’m planning on pulling the PF out for a disassembly and cleaning as well as fix the inserts and the cabinet stability issue.

I guess the last thing on the list will be those gas discharge displays. They look like they could possibly be functioning, but whatever’s driving them could be the culprit.
One foot in front of the other...

I was curious about those. On my Williams, there were little holes to get the flippers set up properly, never seen permanent nail installations under the flippers before. I thought it was a lazy operator, lol

I’ll load it with new balls and give it a shot before I take off. When I tested it at the guys house, it kicked out a ball.
I pulled out the balls that came with it, they were completely thrashed. one was even rusty lol. Glad the machine didn’t work, the playfield would have taken a serious beating with a rusty ball flying around

The Mylar is covering all the inserts that are curling up. Are you saying I should be able to heat them and apply glue from underneath? I’m willing to do whatever is needed to keep it from being damaged further.

On my Williams machine, I was able to use a heat gun to pull inserts that were loose and glue em back in with pretty good results.
Am I correct to assume that these “cupping” arrow inserts can’t be repaired the same way? I was thinking I could somehow trim the Mylar around the insert and attempt the same repair... or is this a bad idea?

Business trip got cancelled right in the middle of a class. Wasn’t even out of town for an entire week due to this corona virus thing.
Gonna go out and hopefully pull the playfield today after testing some voltages

Anybody near me that has a Bally/stern display tester? If I have to, I’ll order one.
Power supply seems to be giving the right amount of juice to drive ‘em, just weird pulsating and such. I don’t expect these to work 100%, but I don’t think ALL of these are toast, but I wouldn’t be surprised.
The display on the playfield for the bonus/timer is fully lit, but it’s doing weird stuff in test mode. 3 zeroes are on the rightmost 3 digits and do not follow the test commands (8 from l to r, 1111111 222222 333333 444444 etc).

Display test results

Saw this in another thread and played around with it. seems like at least 2 displays are working properly (p1 and 2 of course) when separated, but since the machine was disassembled when I bought it I don’t know which display cable goes to which display.
I decided to switch gears and start with the basics.... clean the machine and PF out.
PF is out of the machine to rebuild flippers and work my way backwards. The left flippers are not working and I have a hunch it could be dirty contactors on the enable relay.
It seems to “play” properly other than the left side flippers. Somebody earlier mentioned to get the machine working and then focus on the scoring stuff.
it needs to all be done anyway, I suppose

Found my left side flipper problem- pulled the SDU board with the intention of checking the K1 relay contacts but found this burnt trace instead. Love it when the problems are obvious.
Is it acceptable to just jumper it over the damaged area with wire? I know why it cooked, there were bare wires/fried solenoid on the bottom of the PF.
Not tryna make the worst hack/repair thread

Also, I noticed the bottom (Main) set of flippers have a double contact EOS with the second set to activate the top flippers.
All of the rebuild kits I found have only a single contact EOS.
Anybody got a line on a complete rebuild kit?

Stoked. Pulled the displays and reflowed all the joints from connector to display, solid.
Found a ton of bad joints on the power supply and handled those as well.
Thanks you guys!
The old girl is coming back to life. Rebuild kit on the way. I’m thinking it’ll be playable by next week.

She’s cleanin’ up right nice

It’s running, but I’m having an issue with the flippers “double tapping”.
I have a feeling I have a combination of EOS switches being out of whack along with weak coils.
When I get back today, I’m going to see if I can piece together a better set of switches.
The ones that came with the kit were junk
