Hello all,

I have a strange problem on my WPC Dr Who machine, what's happening is when any solenoid or other flasher activates during game play the Second Chance flasher briefly flashes with them, not sure where to start with fault finding this one.

This problem became really obvious after I upgraded to LED's.

Thanks for the help.

Regards.

Thanks for the reply's everyone.

Problem doesn't exist with incandescent lamps fitted but the LED's are so cool lol.

It definitely seems like a ghosting problem as there is ghosting happening on inserts, just need to get around to flashing the LED MOD ROM to fix that and maybe it will fix that also.

All plugs are in the correct spots on the PDB and was the first thing I checked.

Will flash the MOD ROM this weekend and if the problem still exists will lift the tieback diode on the PDB and post back the results.

Cheers.

Problem was solved by removing the tieback diodes as suggested, thanks very much for the help.
