I just picked up a Road Kings and it has a display issue. None of the 5 displays (2 alpha, 2 numeric, 1 credit/match) work. I swapped the power supply from my Pharaoh and three displays now work. I then swapped the non-working displays to the working positions and that proved they were in fact dead. Checked the high voltage section of the original power supply and it is missing the -100v.

I was originally gonna just buy two glasses and then rebuild the power supply but started thinking I might be better off just buying a PinScore LED set or xPin LED set.

My question is do I need to still rebuild the 100v section of the power supply? I know these LED displays only need 5v and I have tested that (it has 5.01v) so it’s good! Just don’t know if the LED displays still need the 100v for some other use.

Thanks guys!
