SOLVED: TMNT will not boot

I picked up this TMNT a while back and I am struggling with it. It has a new Rottendog board. I added new ROMs to the board and a new Rottendog power board. I turn the game on and the machine does the DMD check and then goes through a bunch of the adjustments and then starts again. I noticed that the DMD was from a star trek and that it had the star trek ROM in it. I am assuming these are not the same DMD because I have a display ROM for TMNT and it is not the same size. Is this what is causing my machine to act like this?

It is the same DMD in both machines. Sounds like you need to replace the display ROM on the DMD since you noticed it came up as Star Trek.

See if you have TMNT 1.04 CPU ROM when it powers up. If not, the CPU and display ROMs are sold as a pair here. http://www.thatpinballplace.com/eproms/de.html Though you can email him and see if he will sell just the display ROM.

I missed this part. Can you post a picture of the DMD and the TMNT ROM together?

What is the state of your original power supply and CPU boards?
If there is no board damage, I would have them sent off and repaired so you can have spare boards to get the machine up and running quickly if was to go down again.

Sure no problem.

It came with the rottendog mpu board. I picked up the power board. I believe the high voltage is out but I will probably go through and fix it

The TMNT ROM seems to have less legs than Star Trek. Yes it will work, but I can't recall if it fits toward the top or bottom part of the IC socket.

So you would have some unused pins in the socket when you install the TMNT display ROM.

Yes, it could fry it if installed wrong.

Hmm. Well then. I guess I need to figure out which side to start from then. Thanks for the help so far this game is about to kill me.

How many pins on it?

I think it would be mounted toward the bottom part of the socket so the top pins on each side are not used.

there are 14 pins on each side I got the ROM from John Wart. I have sent him an email to see what he says.

Perfect. I was hoping you got it from him.
I could not find a picture anywhere on the internet of a smaller ROM being installed, including on Pinwiki. I'm sure it would be added soon.

Post a picture of the ROM installed once you see it working. Thank you.

The ROM works in the lowest position

However the game still doesn't work. It shows the DMD rom info and then goes through all the adjustment list making a tone as it automatically moves through the list. Then it starts over.

Try reseating the ribbon cable again on both ends of the cable.

I just tried it with a brand new connector that I had purchased for another project but did not use. It continued to do the same thing

Do you have pin 1 (red wire) of the ribbon cable on both ends facing to the right looking at the CPU and the DMD?

#23 8 years ago

JPM

Pinside member

If I look at the CPU it is on the right. If I look at the backside of the DMD board it is left but if I look at the front of the DMD it is on the right

#24 8 years ago

If they both sides of the ribbon cable are facing to the left, that is ok as it will just match up pin 1 from CPU to pin 1 of the DMD.

Swap the cable around on the DMD to see if it helps.

I swapped the cable and the DMD would not come on.

I installed the game ROMs as well. I sent the MPU back to Jim at Rottendog to check as well.

You do have the 'B' ROM in the top socket and 'C' ROM in the bottom socket on the CPU?

Are you sure your service switch just isnt stuck? Only reason I see that it would kick right into menus and cycle through them all...

I thought that too. There are only two switches on the service switch. It looks like someone had rigged up a credit button as well.

Can you unplug the coin door connector just inside the door to the left and see what happens?

Can you unhook CN10 on the CPU and see what it does?
Then if same, plug CN10 back in and unplug CN8 on the CPU.

CN8 switch column drives
CN10 switch row drives

I just tried it with CN10 and again with CN8 unhooked. Still doing the same thing.

Can you verify the location of the game ROM's are correct?
'B' ROM in the top socket and 'C' ROM in the bottom socket on the CPU?

Also make sure all the pins are in the sockets. Sometimes a pin gets bent back toward the ROM.
May have to remove each ROM to verify this.

I just double checked. They are both fully seated in the correct location. Possible that the ROMs are bad?

I hope not. Did you mention to John what the game was doing?

Do you have an older set of game ROMs? Doesn't matter what game.

I would not think so either. I did mention it in the email what the game was doing.

I have an older set of game ROMs I can try in it. I will try those real fast and see what happens.

Seems if the game ROM was a problem, it would not boot as in no display and the PIA LED on the CPU would be lit up.
