Hi guys. Got my new machines in, two crazy chairs.. But I have a little problem with one of them.
The 7 seg display on four numbers are not displaying. I've tried changing the wiring over, so basically displaying the 0 where the 7 should be on the £70 area and that works fine.. So the 7 seg is working. I have also tried a different mux board (one i know is 100% working) and same problem, which makes me believe it is either a data wire issue or a power wire issue.
I have tried wiggling the connections, tracing the wires and moving all parts of the wiring connecting from the scorp board to the 7 segs and never seen a flicker from any of the numbers. I've also tried a second light/button board.. And still no joy.. These 7 segs just don't want to light.. Do you guys think it is a wiring fault or a CPU fault.. Spose I could swap the boards over. :S
Do you guys know how the wiring works in this kind of 7 seg?? Eg whether its a chain of wires or 24 different wiring circuits.

From the look of that picture it's probably a hacked ROM, a.k.a. DOND Crazy Chair - One Box Game

 

... as for technical help, I haven't got a clue on this one. Let us know when you work it out though

Yeh it was the board.. You could actually see that some of the chips leading directly to the led output were bent and about 3 or 4 were badly bend and you could see the leg wasn't connecting. Now after changing the board and the mux board I now have a scrambled set of box's with 66. And all sorts of other weird shapes where the numbers should be. I know I need a new board but I know the mux is at fault here as when I put this mux in my other crazy chair, the character were the same eg 66. And other crazy symbols lol.
So I need a new board and a new mux.. Damn,
Lol.. Might make one of these out of this machine lol.

If you need a Scorpion 5 mainboard I have one you could have for £25 inc postage, fitted a new battery a couple of months back but not used since. No leakage or anything. Should be working fine (was in a video cabinet machine), but if you did have any probs I'd refund you. I've got no use for it, all my machines are Scorpion 4 now!

Hi Ben. Unfortunately I need a scorp 4 board. The board I can get hold off no problem, just a waiting game, it's the led output board I'm worried about getting hold of.
