stern wildfyre 6 digit display issues .....
this one is giving me headaches, the 6 digit display at player 3 location (and only at player 3 ) is "ghosting" the credits / player info of the 5th display
i.e. current 39 credits are appearing on flicking display three at same time as flashing on display 5, i have swapped the displays around and problem is only at location of player three, also ran a jumper from the mpu J1 pin 22 to display three pin 15 bypassing the original wire going with no change, displays are known good, header pins have been reflowed and all work perfectly in every location except position for player three
swapped mpu with a known good Alltek - no change so its not the mpu, ghosting problem still exists at player three
connectors appear good, no visible break in wiring are seen
an additional wrench in this mix is that two controlled playfield lamps also are oddly flickering in sync with display strobing, which is some how making me think there is some very strange wiring issue afoot, and there has been alot of wiring repair work done on this one due to mouse modifications
how to sort this out ?
open to any ideas and all suggestions, hopefully this makes some sense
