ROAD KINGS problems [Next step: Drop target]

RayB:
It's not the cables.
I am close to just buying a new PinScore LED display set... But this will bring my total investment right up to the market price of this under-rated, low demand machine (maybe even over it).
 :-\

RayB:
Tested all the resistors and they check out. Must be bad chips.

Pinball Wizard:
I have a complete set of displays and driver board from my High Speed. I'm out of town this weekend but I can plug it in, test it and if it works good I'll sell it to you. I know for a fact that player 3 and player 4 displays are completly dead but other than that the rest looked good when pulled. I do also know that the player 3 and player 4 displays are the problem not the actual driver board. I'l see what is what and get you a price (assuming you even want to buy it).

RayB:
Thank you for the offer! I'll research whether they are compatible or not. Just be warned, I am cheap. Otherwise I would have sprung for the new LED replacement already.

RayB:
Pinball Wizard came to my rescue and sold me a display driver board with displays for a very fair price and it has got me one step closer, but alas, not all the way there.  :cry:

While previously the displays for player 1 and 2 only showed some pattern that didn't change, now I get actual "information" on the Match display, player 1, 2 and 4, however plenty of segments are not showing and some are permanently on.

What's confusing us (PW and I discussed this already) is that this board was tested and working in a High Speed.

So that leaves us with potentially the cables or the main CPU board. At least I didn't splurge on the LED replacements, because if its the CPU board, then the LED displays would show junk just the same.

*(The photos below are with my original displays, but the High Speed driver board. When I had PW's displays hooked up for P1 & 2, all segments showed except for the right side and one of the middle parts was always on)
