Hello, I am very new to collecting, and just encountered my first DMD issue after having friends over last night. The pin is FS. I have posted a video of the issue here:

Game play is not affected, and I can tell the display is reacting to things happening during gameplay.

If anyone can advise me on what steps to take in order to troubleshoot this, i would greatly appreciate it. For what it is worth, I have other Wiliams games like FT, WCS, TAF, and IJ.

Thank you!!!!

Hi Mike, thanks for the help! Here is the update, and I am using FT as the swap pin for the FS repair.

I reseated the cables, no help. I even took the ribbon cable off of FT, and swapped it into FS, no help. I put all cables back to original machines, FT

I then took the DMD out of FT, put it in FS. When I powered up FS, the DMD worked fine.
I then put the DMD's back to their original machines, FT working fine (as expected), FS still exhibiting the issue.

As best I can tell, the brand is Babcock, it has a date code of "4895", which I assume is April 8, 1995.

The bummer is I have only owned this machine for less than two weeks - ugh!!!

So, is it confirmed I just need to replace the DMD? There isn't any simple thing to try just in case? In my case, it is not missing a row, a column, etc.... A lot of the troubleshooting refers to these situations. It is also not a display that is gassing out or weak. It is just firing odd data to the display, as I captured in my video it seems to be trying to work, so maybe just maybe there is a simple potential fix - hoping and praying, and praying, and hoping!

You guys are all fantastic! Thank you so much. I will try moving the FS DMD to FT, but that is a .01% chance, but why not. I am enjoying getting more comfortable with the pins anyway.

I will then proceed to either upgrade one of my pins to Color, or try and get a used one.

Thank you all again - this hobby is awesome, and I waited ten years too long to get started!

So, as expected, I moved the FS DMD to FT, and saw the same type of behavior...

Well, I had not yet bought a replacement DMD yet, and we had a bunch of people over last night, so I thought "what the heck" and I put the DMD back in Flintstones so people could play it.

Well, when the machine started up, I saw the same behavior, then later in the evening while people were playing the DMD worked FLAWLESSLY. Then after a little while longer, it went back to the problematic behavior...

Does this point anyone to something I can try and repair/troubleshoot?

Thanks!
