Question
Grish
Hi All,
Red on my WBML board seems to have died, I have no idea even where to begin with this, I can rule out the cab/monitor being an issue as other boards work fine.
I traced continuity about as far as I could from the red pin on the Sega System 8 connector to a resistor, then other side of resistor it runs all the way over to the other side of the board and finally hits up a chip: GD74LS174 which is apparently a "flip flop" - This is as far as I've gotten.
Before I guess to much, I was hoping loss of an RGB colour would be something fairly common in the arcade pcb world and someone might have a cheat sheet or idea of where to look?
A few pics of the issue and the board over on this board: https://forum.arcadeotaku.com/viewtopic.php?f=2&t=27247&start=100
Any leads would be so appreciated!
Cheers,
Grish
