Great repair! Very curious the positions of the failures there! I saw your comment about manufacturer and batch - very interesting! Thanks for the PDF links, very useful!
I love doing repairs like this, as tedious as they can get. I don't have a Fluke, so my logic probe gets a ton of use LOL. I just fixed a Lethal Enforcers and a Simpsons last week, and they had very similar construction to this. Konami must have stuck with that style for some time. The boards that I really would like more tech info on are Sega's Daytona USA and Cool Riders boards. They are almost impossible to work on with the crazy amount of custom chips, and the stacked construction. Not to mention the corrosion damage from being mounted under the floor boards in the sit down cabinets.
Very awesome! I'm going to have to take a look at that book you have on your website and get 1 of those probes you have. Do you have a tutorial on your youtube on how to use it correctly? Thanks
I have this same board. You wouldn't happen to know what would be causing a coin mech input for Colossus to be stuck "on", would you? It shows this even when no micro-switch is connected.
These PCB repair videos are incredibly helpful, as well as entertaining. Thanks for posting, and please keep them coming!

Excellent video that makes me kinda WANT to repair PCBs as an extension to my vintage computing hobby XD... there's something wrong with that lol.
I just subscribed in hopes for more arcade troubleshooting videos.
Most likely it was that one batch of components. All the failing TTL was of the same type and by the same manufacturer if I recall.
By the way I can't find the online version of your TTL data book on your website anywhere. Can you please point me in the right direction? Thanks
What do you call the vice that you use to hold the pcb sideways? I need to get one of those :)

Hi! How do you ON the second monitor on this board? Is that pins close the joystick pins? Thanks!
@arcadeuk Google "panavise". Although I'm sure other companies make them too. Just do a search on Ebay for "pcb vise"
is this the board from Fall River?
Tnx for this nice Tutorial, i will try to repair Silkworm :)
it has some HSYNC problems
Thanks. I learned alot from you.
@freethinkerpro If a particular game works fine in one 'mode' but not in another, it's typically a program ROM issue.
Sure I'll add it to the video notes
Nah this is the one that came with it.
i got a pcb with 13b error
Yep... that's the one.
Do you think you could fix a graphics issue on my xmen board? I'd send it to you and pay handsomly!!! =)
Thanks a lot man. I got it. =)
