Model AD 5000 English Mark Darts

[Papaed57]

Hi everyone, very nice forum!

Get right to it...  Just attained the English Mark Darts mentioned in the subject line.  Everything is functional, circuitry is great, all surfaces are great.  I am having a problem with no darts registering on contact, except for on the 17 and 1, and when it does register there it is scoring 4 every time.  I have a suspicion the scoring membrane is not staying in place and wondered if any of you have a cure, or another possible explanation for the darts not registering.  I watched the guy I got it from check the circuitry, and the built in self check does fine.

Any help is appreciated.

That one is older than mine, right?

I am not sure about that model but I'll tell you how I fixed darts not registering on mine when I got it.

#1 -- The dartboard head plugs into the PCB with a ribbon cable. Check that. Make sure you have a good connection
#2 -- Remove the head from the game and take the entire thing apart. Clean it. Remove stuck dart tip pieces. Make it like new.

Hi John, I'm not sure which model you have, but this is one of the early ones from what I've been told.  The Owner's Manual has a stamp from Arachnid dated 1982.  It doesn't even have cricket on it, which is kind of a bummer, but it's fun just the same.

We've tried both of your ideas, to no avail.  We've had the membranes off several times and even managed to get it to work for about 5 or six darts, registering properly, and then - bang, it stopped scoring again.  I repeated the same method two more times to no avail.  I'm thinking this is probably the reason the guy I got it from got it so cheap.  He was told it was a basket case and bought it for spare parts, got it home fiddled with it, and it worked fine, so he offered it to me at a very decent price.

I'm trying to avoid buying a new scoring matrix if I can, but it's looking like I may have to.  I have all the documentation for this board if anyone is looking, by the way.  I know the Owner's Manual is available on line, but I also have all the schematics.
