Both flash lamps that aren’t working are socketed, not on boards. Both have continuity to the sockets from the driver board.

Do they light up when you shirt the transistor?

If yes, likely transistor (or predriver transistor) is bad.
If no, then they're not connected to the 20v feed.

#3603 4 years ago

How would I go about shorting the transistor to test? Do you do this with the machine powered on and everything plugged in?

Is the predriver transistor 2N5401?

#3604 4 years ago

Hi Guys,

Anyone have a full list of screws / bolts / nuts if I want to replace everything on my playfield ?

If it is in the manual can some one provide a reference?

Cheers

its there. I used it extensively during my restoration.
Get to know the manual page by page. Its VERY informative.

Print out a copy and spiral bind it with plastic covers.

another source for part numbers is marcos website.
they break down the sub-assemblies by their part numbers. Its amazing!

I think the ipdb.org has a parts list in text format

Still need someone to.confirm my wiring colors on the opto carrier? Please and thank you

Did you look at the picture I posted when I did mine? Post #3415
I dont want to pull mine apart again....yet...

I dont know If I have a picture of the connector side.
I think its in faz's guide.

I did look at yours, kinda unclear of certain colors. Do not pull yours apart, it is working. I am going off of Faz's guide, so I just wanted to be sure.

Anyone have insight on this? I have a new TIP102 transistor coming this weekend and if the predriver transistor is a 2N5401, then I already have a couple of those from a previous display repair.

Shorting is not the most accurate way to prove a bad transistor. Beat way is to test it with the meter

Mine is currently disassembled. I will get down to the workshop tonight and get what you need.

I am so happy and so mad at you for having a working game lmao. Looks awesome. Did you motorize that topper? I did mine, was easy and does add a nice element.

looks great, have fun

Dont be mad...lol.

Ive been exactly where you are.

Months of tedious testing and trouble shooting. Hours of testing and research and schematic reads.

Many Days of internet searching and parts accrual.

Every single mech had to be compared to the manual and correct parts acquired.

I think ive almost memorized the manual at this point.

The hundreds of hacks and operator nonsense caused me to go full bore and rip everything apart.

By far the most frustrating and rewarding restoration i have done.

If i was to do a motorized topper, i would do the earlier build using the motor that marco still has.

And the original type construction of the first 100 games.

I would fabricate the bracket and order some pc board blanks made up ftom the way earlier build.

The servo build isnt as robust and doesnt interact as well as the original design.

It costs $500 or so but, it would be a fun project.

I wanted to do the original, and have seen the complete kit on ebay. I wanted to re fabricate the kit as well, in a small batch run.

I am not giving up, I am gonna move on to my Terminator project and finish it. Then.....get back to the Doctor. Just bizarre how when I plug the connector from 5-target opto carrier, to opto interface board, it scrambles the input signals. When I unplug it, the inputs are normal. Never have I ever seen this with a game. I will also be pulling the playfield to check all the wires for breaks and such.

I'm in for the small batch production run.
Lets do this!

No hurry, but that is the type of motorized topper I want.

Ill start putting together some odds and ends, who knows? I might have something for the summer!

Anyone else want to investigate this?

Check back in your mind what was going on when it was working.
Review all of the prior repairs.

Sounds like a bad connector/short/mis-wire on one end or the other.
Or a mis-wired repair from the past (I found a few of those).

Here's a thought:

Pull the the wires from the connector.

Attach via micro jumper each wire, one by one.
Examine the results wire by wire. check the paths.

I imagine the results would be enlightening.

This could give some insight as to what is mis-wired or shorted or at least point to a specific circuit...

I also agree this would be way easier with the playfield on the rotisserie.

I guess I was lucky snagging one of the reproduction kits of the original style motor. That was the only way I was going to add it as well. It’s overkill in the design but shouldn’t ever fail. I doubt the servo version would hold up.

I pulled the playfield out and all wires. When I was putting back the pindora boards and raised the playfield, I had switche 75 register in switch mode, so I am sure I have broken wires.

Its late in the game but, This is the only mod I would actually want to do.

Have you collected any info on the original kit?

I know marco still has some motors with gearbox.
Im going to snag one of those.

I want to replicate the original kit pc board.

There is a ton of pictures on the basement arcade site. They made the reproduction kit of the proto topper. Maybe he has left over parts.

Making a reproduction of the PCB portion would be easy.

Do you have a "quick cad", for this board?
I can have some populated boards made if I have the cad drawing with parts list..

these guys are fast and inexpensive:

https://www.pcbway.com/

I have had them reproduce boards in the past.
They also can work off a photo if you have the measurements and mounting hole locations.

Ooh! I checked my mail today, and not only did my swinks opto carrier arrive, so did the pindora opto boards! Looks like I will be playing soon!

Nice. I recommend buying fish paper and making a shim for to raise the blue board off the carrier so no e-clips ruin the IR LED's.

I am trying to restore a Dr who which is not in a very good shape.
I found these 2 wires under the upper flipper going nowhere...I am not sure if it's normal or not, can someone confirm it? Thanks.

Those are your EOS wires, all the flippers should be tied together and go back to a .100 connector.

#3645 4 years ago

Update: found a few wires with exposed wiring, but no breaks. Still on the hunt for damaged wires, what a tedious process, one wire at a time.

I had some intermittant contacts.

I found a lot of loose wires on the IDC connectors.

I replaced some connectors, others i cut back the wire and reinserted it with a tool.

A couple others i installed trifurcon in tbe GI.

There are no loose wires in the game.

They all are supposed to be attached somewhere.

Remember, I spent 4 days sorting out the topper light lol.

Finally went to the schematic and checked wire by wire.

What a PITA!

Fish paper or gasket material is the best as a spacer.

If you don't have any,

I used 3 layers of black electrical tape, it was the proper thickness.

Thanks for posting a pic!

It verifies that they went to clear opto transistors, instead of the red.

Please post more pics if your progress.
