I just tested IC9 and IC10 which are UDN7180 chips.
First, I put the game in display test mode.
On IC9, pin 2 is input and pin 17 is output pin. I can see the input pin 2 cycling between 0 and 5 volts as expected. However the output pin 17 is stuck at -97 volts.
On IC10, it's the same. Input pin 8 is cycling between 0 and 5 volts. Output pin 11 is stuck at -97 volts.
I tested a few of the other output pins on IC10 (which is easier to get to). Those output pins were cycling between -27 volts and -97 volts.
So it seems like the UDN7180 chips are the cause of the problem?
What about the burning resistor at R11? Is it the same root cause, bad 7180 chips?
I know these 7180 chips are hard to come by now. I have some display boards from my Bugs Bunny which are missing the actual display glasses. In my Bugs Bunny, I replaced the displays with new LED boards. I don't know if those chips are good because the display glasses were removed prior to me acquiring the game. Is it worthwhile trying to harvest these UDN7180 chips? I'd probably have to get help from a friend who has a better desoldering tool to get those chips off the board intact.
