          I would be pretty certain Skybeaux (pinball repairman in your area) would have some and if not I have dozens of NOS ones that came from the Hankin factory in fact.

          ....or as Wiredoug says, if your board is toast replace it with a redesigned one that won't have the same problems as the originals did/do.

              I've turned down a few Hankins over the years because of non-working boards.
              Now we have boards we can rely on to get us out of a fix, I can't get a bloody machine!

                I'm sure there are plenty of dead Hankin pins stashed in sheds just waiting to be rescued.....

                    Yes.

                    The 7406's are more likely to be suspect however.

                      thanks for all the help guys. I'd prefer to fix it myself to start with as it gets me more experience with fault finding on this machine. I bought the machine about 15yrs ago and have had a few problems. But I like the game and don't think i'll ever part with it. it plays well and I like the that it has a lot of drop targets. Anyway, i'll buy some parts from Skybeaux, if it doesn't fix the problem i'll buy a new board from Homepin. Thanks again.

                      PM sent.

                        OK. Replace IC1 and still no luck. all the lights that don't work come from IC1. How would I go about chasing this issue. I'm assuming it's an input issue from P1.

                          The original red brown ic sockets on the Hankins are another possible cause. Most of my Hankins have had the sockets re done.

                            Thanks. the only red socket is on the MPU board. I took out ic1, put in a socket and new ic and still no good. i'll need to work out how to trace the issue from the P1 plug.

                              The inputs are all paralleled across all the four chip with the chip select line being the only one that differs. If there was an input signal issue it would be occuring on all four chips.

                              I'm thinking it's more a playfield supply to the OTHER side of the lamps issue rather than a board issue???
