Williams Pinbot Restoration

[Strangeways]

possible fault with the ribbon cable between cpu board and master display, or the headers for the ribon cable need cleaning,or cracked/dry solder joints on ribon cable headers if you have another ribbon cable try swaping it or try moving the plugs on the ribbon cable up and down while it is on and see if it runs properly,
My bk 2000 has the same problem, when i move the plug on the ribbon cable (cpu side) it works properley, try both ends


on another subject i noticed the top of the vortex is broken, if you want to fix the top of the votex here is a link to show you how http://www.stevechannel.com/pinbot.htm
just thought i would share it with you

Cheers Beaky !

I'll give it a go tonight - and thanks for the link - interesting repair.

Thanks to a process of elimination, the display problem is due to what appear to be an internal short on one of the 7 digit alphanumeric displays. One display works perfectly until I plug the faulty one in, and the when the bottom RHS segment on the far left and centre digit switches on - it also switches on the lower horizontal segment. This also happens one the "good" display.

Bloody williams displays !!

So I will need a replacement display - Part number 5769-10874-00 (7 Digit Alpha display). I will post a request for one on the "parts wanted" section.

Thanks a bunch for the detailed thread Nino - it really helps to see some of the steps involved. Have often heard of the term 'tumbling' in regards to cleaning playfield parts but have never really seen it done.

Great thread for us 'noobs' to follow.

OK - Been busy on other things and the Kohout Alphanumeric display arrived. I installed the plastic protector and tested it in the machine. Obviously it worked very well and it did not "stand out" from the old display (Right hand side). So the problem was the old display (replaced) had a short that affected the other alphanumeric display. So the game is working well at the moment ;







I also repaired the light blue plastic and made my own custom protector. The break was right in front of the ramp flap armature. I also like this photo without the flash and with the glass on !





I will take some final shots of the completed machine, and then it will be up for sale

The machine is completely finished and has been play tested thoroughly by my nieces and nephews ! The only thing I didn't do is replace the spiral ramp, it is chipped at the very top and it does not affect the gameplay. Everything else is working 100%. The modified flippers (serial coils removed and newer parallel installed), are powerful and the rampshots etc are easily made.

The treasurecove kit makes a HUGE difference and I would recommend using it on mylared playfields.

Here are some final pictures ;










I will be selling this machine to make some room !

That is one game that is on my wish list!

Great to see such a high quality example.
