In regards to Dragons Lair LED score disply:
The below was an online article:
Symptom: Score board displays dim F's when not displaying anything:
Fix: The cause is from pin 9 (mode input) of the ICM7218 display driver ICs being unloaded. Connect pin 9 of both display drivers together then connect one end of two 1k resistors to pin 9. Connect the other end of one resistor to +5V and then the remaining one to GND.
Is this on the main board???
What exactly is the display driver???
thanks
