Quoted from Blitzburgh99:

Finally got my EBD up and runnng, playable and into the game room after sitting in the garage for almost a year!
Anyone with good suggestions on adding LEDs? Brand, colors, etc

Quoted from Blitzburgh99:

Update: reseated all connectors and all the little gremlins seem to have disappeared...but new problem. None of the displays are working. Which connector is responsible? Has to be a connector??

Quoted from HPR:

All transparent plastics are home made with polycarbonate, they won't brake anymore.

Quoted from BJM-Maxx:

Embryon has metal guides.

Quoted from Gatecrasher:

I wouldn't say one color was an absolute for 1984-85 but a lot of them had yellow flipper rubbers but I've seen some with the red ones too. It's hard to recall plus most have been replaced several times over the years.

Quoted from Gatecrasher:

Yeah but then it doesn't look they way it is supposed to. For those of us purists who played these machines when they were new, LEDs look wrong. Younger pinball fans who weren't around back then are usually more open to mods like this.

Quoted from Humph:

Thx -- will do, that's my next step.

Quoted from shutyertrap:

Okay, need some help. Replaced very cooked knocker coil with new one, but it still doesn't trigger. What should I look at as the culprit?

The more detailed the troubleshooting advice, the better! I'm new to all this.

Quoted from manples:

Ok this is either a newbie question or a weird thing that you will debate about soon
I was checking the pin headers and noticed they all have what I thought was a burnt pin:

In fact these dark pins are full of a greenish grease... What is that ? Some "contact" grease maybe ? why ?
And it seems to have a pattern, like pin #9 from the right. Please tell me it's ok and I don't have to replace them all I've tried to clean one with alcohol and an air gun but it's always there...

Nasty stuff indeed. Repin both sides as soon as you can. The slime will effect the connection which makes it run hotter and builds carbon quicker, etc, etc...

Quoted from PinballTilt:

Thanks guys, I'll check these protectors out.

Quoted from Humph:

That looks interesting.
Does it blend well with the outlanes & can you post pics after installation ?
I may want to do something similar during my EBD resto.

Quoted from Lovef2k:

There's no need to remove the entire bank from the pf. Just unplug the 9 pin connector, remove 2 screws from each side that holds the memory coil bracket in place. The coils look correct, drops for ball 1-9 and 2-10 are controlled by the SEB, that's why they have the extra lug. Make sure the plungers for the other 6 memory coils move freely. I don't think the SEB would cause a coil to fry, only fail to switch from one coil to the other if it did fail. I would suspect the driver transistor.
With the memory coils unplugged, do the other coils fire during self test?

Quoted from Troyster42:

Hi Guys,
Hoping for some help. I picked up a EBD LTD for a friend last week. It will be his first pin and I wanted to look over it a little. Everything works and plays fine. The MPU goes through the 7 flashes and the sound 5. This still has a rechargeable battery on the board, I’m pretty sure its not original. When I first looked at it the sound was set to the default chimes I think it wasn’t played enough and the battery drained. I went into the self test and set it to 03 so it sounds normal again. Now I can’t get back into the book keeping or adjustments. I can do the self tests and when I push the button again there is nothing. Even trying to push it 23+ times there is still nothing just the GI and the only way to get out of it is to turn it off and back on. Its still retaining the sound setting and high score. Could it be the ram chip is going bad? I was going to suggest to him putting a 3 aa battery pack off board but if it could be the chip maybe go with a nvram from Pintech, simple swap of the chip.

Quoted from Tember:

Great thread...
I am restoring a very tired EBD, all harnesses etc, I am thinking I want to replace the #555's with bayonet holders.
Is that generally the most reliable solution?
Ted

Quoted from jj44114:

His stencils are garbage.

Quoted from Gatecrasher:

Me too.
I leave my coin mechs fully operational and do not have free play on any of my pins. Free play ruins the game for me.

Quoted from Mathazar:

First impression to me is a lamp matrix addressing issue. I'm assuming it's never worked for you since you just bought it....do you know the repair/upkeep history of the machine from the previous owner? First thing I'd do is re-pin the J4 connector on the Lamp driver board (which contains the four lamp matrix addressing wires). Prior to that, you could try pulling off the connector and re-seating it, and/or while the game is running try wiggling that connector and see if the behavior changes. If it does, that's your culprit. If it doesn't, I'd still repin that (and pretty much all) connectors on the nearly 40 year old machine. Re-pinned connectors often fix many squirrely issues.

Quoted from phillyfan64:

What do people use to replace the peeling off foam strips on the ends of the original displays? There has to be something better.[quoted image][quoted image]

Quoted from slicknick13:

So I grabbed this freebie the other day. It's missing a lot and has a cut harness, but the only spare parts I'm missing are a slingshot and the 7 bank drop target. I have enough bally scrap wire around to make the rest of the harness and I'll just make a molex splice.
I think I can make a game out of it on the cheap. One of those no-rush, grab the parts when I can deals. I'll make a thread when I get more stuff.
At the very least, I can drop it into my Kings of Steel cab until I can get the transformer and cabinet squared away.

Quoted from pacman11:

Yes, installed correctly doesn’t work for orginal board or alltek. Thanks! Probably a connector issue but I am trying to figure out which connector is the problem.

Quoted from Boltronix:

That pf is looks pretty nice. How much you want ? I would get her up n running than fine tune it all. this game is awesome.
