New thread kinda the same as the wpc driver board I repaired for a fishtales a couple of weeks back.

Generic WPC Driver board repair thread

Connectors will all be inspected and if needed repaired.

Major connectors are the J115 J120 J121 that usually have the most damage.

The J121 J120 headers and connectors will need to be replaced.

J118 header looks fine, but connector is burnt. Will replace header as well, as it has been stated the headers oxidize and create more resistance.

J118 is also the 12v feed for the mini playfield driver board and motor... Such as in indiana jones.

Here are the pics I have so far of the damage.

This is repairable, j121 pin 1 has me worried as it is loose... That means the pad underneath is most likely... Fucked... So I may have to wrap wire around the pin, solder it to the pin, and make a wire jumper from j120 to j121 bypassing the trace... No biggie and it will likely not be seen

There is a through hole trace on j115 that has to be checked also, as the top of the trace supplied a triac with voltage, it is easily overlooked, but checking for continuity on that top pin to the transistor will show if the mod is needed or not. Been there done that.

Once I repair this board, another member has another driverboard from his wpc getaway that has gi lights out, and I believe is the same issues. That would be my third wpc driver board repair.

It must be stated, the pads fucking suck on these boards. I am not looking forward to doing a cap kit when the time comes on one of these.

Through hole trace repair

Pad repair, coiled bare copper coldered to the pin, and a leg to the trace, reinforced with more solder to form a solid connection.

According to eldorado games this was a $110usd repair +shipping each way.



I hope this helps someone, pm if someone needs this type of repair

Very nice. I don't think I've ever seen or had a Williams system 11 or WPC pin that didn't need at least one of the headers and connectors replaced. Toasty GI. :)

Very common, this type of repair is tricky with the through hole bit, but it is possible to make the repairs look good.

There is no fixing chared pcb tho. The discoloration persists.
 
Eyelets? Didn't know they made something like that.

yea... what?

link plz.


also this is what I love about klov. I am doing repairs the way I was taught in college. much less advanced equipment... but still
 
...tedious AF. But i can see the appeal...

I still say with wire you run less of a chance of it burning given the increase of currant it can pass
 
Before I set the eyelet I clean the pad it's going through, set the eyelet and then solder the eyelet to the pad.
 
I do not argue it is more cosmetically appealing, but both are modification upgrades/repairs.

I do not have that kind of cash for those super specific tools.

Its almost like when I did grommets on banners at the sign company I worked at in high school for 3 years.

Ugh 6 color screen printing... Making screens, emulsifier going bad... Washing screens, repairing screens, screen printing....
 
This is great stuff, no matter which method you choose. Thanks for posting!

Tucking it away for future repairs. I've had to re-pin a bunch of those connectors but haven't run into burn like that yet.....yet ;-)
 
Did you replace the IDC with molex and trifurcon? Damn those IDC to hell for burning and providing bad connections.

Connectors were labled as molex square pin. Pins were trifurcon. With the 3 side connector.

Glad this helped someone else.

It's a commn repair... But not well documented

If you enjoy repairing pins, good video series is Clay Harrell's "This Old Pinball". That's where I learned the "stitch" method you used as well as some other stuff. His pinballninja.com site is also a great resource, though unfortunately he hasn't updated it since May and it requires a small one-time fee to join. Still a ton of good info though.

Rob Craig's "Life After Death" series is also good. Popbumper.com.

Just figured I'd throw out some unsolicited recommendations..... [emoji6]

And no, I don't get any kind of kickback from those guys.

I think I spent around $20 on the tool. It's literally a die in a stand and a punch. I'll take a pic of it later.

I'll check it out. Perhaps they have a better method, i'm always willing to learn new repair tips and tricks.

I just really like electronics repair... Almost more than the games themselves.

I've been saying that for years. I think I like fixing these guys up more than playing them sometimes.
