ROAD KINGS problems [Next step: Drop target]
RayB:
Thanks for the great tips. Here's the thing... The previous owner connected the power connector to the display driver board 1 pin off. This damaged the board and likely sent high voltage back to the motherboard. The display driver currently in there was pulled working from another compatible pin.
I took the plunge and bought a new Pinscore LED set. It displays the exact same garbled characters and locked on segments.
So, I'll follow your #5 and #6 tips above as best I can but I think I should just send the mpu board out for repair. Where should I send it?
StephenH:
I would see if the Pinscore has issues with the same segments being out or on all the time as the original display. Since the Pinscore had similar problems I am convinced that you have a problem somewhere in the data path from the main board to the score display.
See these articles for the segment names:

RayB:
I'll be pulling the mpu this weekend and testing the points you mentioned. Then it's Probably being mailed off for repair. :-)
RayB:
Who was it that suggested a PIA was bad? The board had two bad 6821 chips. The tech also upgraded the ROMs to version 4 (they were version 2)
Any day now I'll be playing this thing like it was meant to be!
RayB:
WOOOOOoooooooOOO!
I now have fully working displays, on bright shiny new PinScores!
The tech was kind enough to upgrade my ROMs to v4. Please tell me if this sounds like a programming bug though, because it never happened before (and I played the game a good 20 to 30 times even without working displays):
The game has 3 ball lock spots, but is a 2-ball game. When playing, I got a situation where one ball was locked (upper left), and the ramp lock (upper right) was flashing (ready to get a ball and lock in other words). The middle outhole was not active for ball lock yet. Got the ball in there and nothing happened. The ball stayed in there and more interesting is that the game didn't go into "Where's the ball?" mode (you know, that's where all the solenoids start kicking to find a stuck ball). So it just sat there. This behaviour never happened before, in the 20 or 30 times I've played. If this were in an arcade situation, the player would have to abandon the game.
RK did have a v5 upgrade but there's no good dump of it anywhere.
