Hi, got my first pinball machine about 7 months ago. WWF Royal Rumble. Its batteries had leaked all over the main board. I sent the board to AVP Pinball Division in Baltimore about 6 months ago and just got it back. They reinstalled a new battery holder and a few other ics on the board. The board tested well according to the two lights. I did notice that the 3rd from the left 7408 ic was loose from the socket they installed.

Once I reinstalled the board and plugged it in the left backboard lights were out and none of the coils working. The flippers were working. Then it would instantly blow the F6 Fuse.

The balls never came out and the coils not working. Im new to this and need a place to start. I probably should have just bought a replacement board. But Im wondering if its even the main board or if it could be anything else. Checked all fuses, solder joints on the ppb board.

Help?! Where do I start! Should I take the board back to the repair shop. I can solder and work on boards but am not that familiar with pinball machines, but would like to be!

Here is a video of what its doing.

Check to make sure all of your wires are connected properly to the board. You might have one connector plugged in wrong and it needs to be moved over by one pin.

Have you triple checked that you put all the connectors into the right spots ?

I see F6 is the solenoid fuse.
Replace it with the correct rated fuse.
Then turn the machine on and it willl be very quick, look and listen for if only one certain coil is locking on before the fuse blows.

So Im probably gonna have to wait till tommorrow for fuses. I uploaded 2 more videos of my boards.


I do realize there are 2 fuses missing as I was ran out of fuses.

In doing so I saw that the connector at J5 was severely burnt. Could this be the culprit?
Also is it normal for C18 to not have a connection at all?

Alright first C18 shouldn't have a connector so that's normal

Your burnt J5 is probably the reason why you don't have all your lights. That connector is what powers all the lights that are out in your game. When you get new fuses or a circuit breaker (more on that later) keep J5 unplugged and start up your game if the flippers work and nothing blows then it's definitely that connector. With J5 unplugged you should lose the GI lights but the game should work like normal.

Unrelated to the connector but sometimes the coin door switches need to be pushed in or pulled out for the flippers ball eject and the rest of the coils to work. It's a safety put into the games so when you have the coin door open you don't shock yourself by accident. Theres been times I was fixing my game and I forgot to push or pull out the switch and the game will start but no flippers or ball eject.

Your videos were pretty good but I personally wouldn't be able to tell if all your connections on the top row are on the right spots especially the ribbon cables. Though they are facing the right way cause the red line faces the right side of the game when looking at it.

Here's a few things you might want to invest in

First is a NVRAM extremely easy to install on Royal Rumble just unplug one chip and put in this one. This will eliminate the need for the 3 double A batteries. It'll save your scores and settings. And won't leak battery acid on your board. There are cheaper places to get them but pintech will make sure you get the correct and best one for your game.

Also if you plan on getting more pins (or even if you don't) look at getting a few different rated ones of these circuit breakers. Great for chasing shorts you won't need to keep wasting fuses. Just push (or twist) and they reset.

They are just for testing though. Once you fix the Short you can go back to a regular fuse.

Also greatplainselectronics.com is a great web site for buying a new J5 connector, pins and fuses.

Lastly this one isn't a necessity like the other 2 but more of a shameless plug. A color screen DMD looks really nice. Heard the guy that colored it is awesome as well

Hope this helps.

I actually bought the vram but the tech that worked on my board said it didnt work with it. Which i thought was odd. That color display is cool, but i gotta get up and running first. Another thing I saw was some smoke coming from one of the coils. Does that mean it needs to be replaced? It did this when i didnt have everything connected to the main cpu.

Another thing I have found is that when I insert the test ic, the flippers and coils seem to work.

I wonder if you got the wrong NVRAM. Some are modded for different brand games. Take a pic of yours when you get a chance but it's not a priority right now.

The smoke coming from one of the coils means there's a short somewhere to that coil. It could be wires are crossed somewhere or the driving transistor is bad and will need to be replaced. What coil was smoking? Try to follow the wires from it and see if something doesn't look right. Also inspect the coil. If the inside is melted or the wire on the coil is broke now it will need to be replaced. If you turned the power off quick enough you might have saved the coil.

I'm not following what you mean about your test IC chip? I am no means a professional pinball repairman so it could just be my lack of knowledge but I never heard of someone needing a test IC chip. Unless you have a second IC chip from another game that you know works.
