hi!
I started repairing with a pitfall pcb. one day everything worked fine. I encountered this error another day. I started watching the sync. I saw that no signal is coming to the sync pin.
the sync output goes into a 74ls68 for pin 11. pin 12 goes to an unknown component (PIC)


Unfortunately the PIC? IC no inscription. Does anyone have an idea what I can do now?
thanks
