I recently purchased my first sega pin Frankenstein and am loving it so far. The pin was in rough shape, and must have sat in a bar for some time since every part of it was covered in soot and beer stains. But it is tough and with a lot of cleaning and care it now plays great.

I have upgraded the lighting, and replaced the weak flipper coils with one's from GNR. The game is super fast and hitting the ramp is much easier. I even repainted Frankie since he looked a little too cartoonish. All I have left to do is install mirror blades.

The only issue I am having is when I turn on the machine, the voice gets cut off. It says "Franken...." and not the whole word.

Sorry that no one has responded to your issues. I wish I could help you with your pin but I am not experienced enough to give you advice. So let’s treat this as a bump and hopefully someone with expert knowledge help you get your issues resolved.

Btw- For the display, did you try reseating the display roms on the boards? They are real tough to get off but maybe there is a pin broken or bent somewhere. Also I had a display issue on my Frankenstein and there was a service bulletin with an updated cable from Sega. Good luck.

I have never heard of them corrupt or going bad, and it seems you have a good understanding of basic electronics. The only other suggestion that I have experienced is cold solder joints. I always reflow the solder joints on a circuit board when i cant find any other issues. Sometims its hard to see these and has gotten me out of a jam from time to time. Good luck to you.

I have had to reflow solder joints in the past and sometimes you can’t see cold solder joints by a visual inspection. There are a few posts on here about that but it is pretty simple and a little time consuming. You are correct and not recommended to stick boards in the oven, but a hot iron and a little flux paste will work well. Also reseating all the the ribbon cables and connectors on the boards may help too. Look for discolored or burnt looking connectors and any loose wires in and around them. Lastly, this may be obvious but check the fuses since the slow blow kind are hard to tell visually.

Very underrated pin. Durable and easy to work on. The ramps are unobtanium so be careful with them. The dmd is problematic and needs the updated harness if not installed already. If your display resets or is out, look for the service bulletin replacement harness to fix your problem.

Get the natural white bulk packs from comet. I put them in my Frank and they looked great. Kits are good but you can save some $$ by doing it yourself.
