Combatribes Arcade PCB repair
This time we are trying to fix a Combatribes PCB - a beat em up arcade game by Technos Japan made in 1990. There is a graphical issue with the board - there are white horizontal lines all over the screen. This time even without the help of circuit schematics we manage to track down the problem mainly using the continuity tester, oscilloscope and logic analyzer. Enjoy!
